Write a C program to input basic salary of an employee and calculate gross salary according to given conditions.
Basic Salary <= 10000 : HRA = 20%, DA = 80%
Basic Salary is between 10001 to 20000 : HRA = 25%, DA = 90%
Basic Salary >= 20001 : HRA = 30%, DA = 95%
Your program must calculate each employee's gross pay amount.
Answer:
Written in C
#include <stdio.h>
int main() {
float salary;
printf("Salary: ");
scanf("%f", &salary);
float HRA, DA;
if(salary <= 10000){
HRA = 0.20; DA = 0.80;
}
else if(salary >= 10000 && salary <= 20000){
HRA = 0.25; DA = 0.90;
}
else{
HRA = 0.30; DA = 0.95;
}
salary = salary + salary * HRA + salary * DA;

Convert the following C program to C++.
More instructions follow the code.
#include
#include
#define SIZE 5
int main(int argc, char *argv[]) {
int numerator = 25;
int denominator = 10;
int i = 0;
/*
You can assume the files opened correctly and the
correct number of of command-line arguments were
entered.
*/
FILE * inPut = fopen(argv[1], "r");
FILE * outPut = fopen(argv[2], "w");
float result = (float)numerator/denominator;
fprintf(outPut,"Result is %.2f\n", result);
float arr[SIZE];
for( ; i < SIZE; i++) {
fscanf(inPut, "%f", &arr[i]);
fprintf(outPut, "%7.4f\n", arr[i]);
}
return 0;
}
Notice this is uses command-line arguments. I have provided an input file called num.txt that will be used when running the program. The output file is called out.txt.
Make sure you are using C++ style file I/O (FILE pointers/fopen) as well as regular I/O including the C++ style output formatting (fscanf, fprintf, formatting). Also use the C++ method of casting. The lines above that are bold are the lines that you need to convert to C++. Don't forget to add the necessary C++ statements that precede the main() function.
Answer:
The program equivalent in C++ is:
#include <cstdio>
#include <cstdlib>
#define SIZE 5
using namespace std;
int main(int argc, char *argv[]) {
int numerator = 25;
int denominator = 10;
FILE * inPut = fopen(argv[1], "r");
FILE * outPut = fopen(argv[2], "w");
float result = (float)numerator/denominator;
fprintf(outPut,"Result is %.2f\n", result);
float arr[SIZE];

In a system where Round Robin is used for CPU scheduling, the following is TRUE when a process cannot finish its computation during its current time quantum? The process will terminate itself. The process will be terminated by the operating system. The process's state will be changed from running to blocked. None of the mentioned.
Answer:
B. The process will be terminated by the operating system.
Explanation:
When Round Robin is used for CPU scheduling, a time scheduler which is a component of the operating system is used in regulating the operation. A time limit is set for each of the processes to be run.
So, when a process fails to complete running before its time elapses, the time scheduler would log it off and return it to the queue. This queue is in a circular form and gives each of the processes a chance to run its course.
Based on the information given regarding CPU scheduling, the correct option is C. The process's state will be changed from running to blocked.
It should be noted that in a system where Round Robin is used for CPU scheduling, when a process cannot finish its computation during its current time quantum, the process's state will be changed from running to blocked.
It should be noted that a prices transition to a blocked state occurs when it's waiting for some events like a particular resource becoming available.

Create a TeeShirt class for Toby’s Tee Shirt Company. Fields include:
orderNumber - of type int size - of type String color - of type String price - of type double Create set methods for the order number, size, and color and get methods for all four fields. The price is determined by the size: $22.99 for XXL or XXXL, and $19.99 for all other sizes. Create a subclass named CustomTee that descends from TeeShirt and includes a field named slogan (of type String) to hold the slogan requested for the shirt, and include get and set methods for this field.
Answer:
Here is the TeeShirt class:
public class TeeShirt{ //class name
private int orderNumber; // private member variable of type int of class TeeShirt to store the order number
private String size; // to store the size of tshirt

A country, called Simpleland, has a language with a small vocabulary of just “the”, “on”, “and”, “go”, “round”, “bus”, and “wheels”. As per the given scenario, the vector of counts will be 2111211. The correct option is C.
What are the ways to count items in a vector?C++ has a built-in function that counts the length of the vector. Size is the function's name ().
It returns the size or total number of elements of the vector that was utilized to create it. There is no need for debate.
The number of observations (rows) includes deleted observations as well. In an SAS data collection, there can be a maximum of 2 63-1 observations, or roughly 9.2 quintillion observations. For the majority of users, going above that limit is quite rare.
The vector of counts in the above scenario will be 2111211.
Thus, the correct option is C.

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation
Answer:
speed and storage
Explanation:
The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.
Array Implementation:
Pros: Much Faster and Easier to target a specific elementCons: Much More Space neededLinked Implementation
Pros: Less overall space neededCons: Much slower speed.A bank has three types of accounts: checking, savings, and loan. Following are the attributes for each type of account:
CHECKING: Acct No, Date Opened, Balance, Service Charge
SAVINGS: Acct No, Date Opened, Balance, Interest Rate
LOAN: Acct No, Date Opened, Balance, Interest Rate, Payment
Assume that each bank account must be a member of exactly one of these subtypes. Using generalization, develop an EER model segment to represent this situation using the traditional EER notation, the Visio notation, or other tools like Lucidchart / Draw.io. Remember to include a subtype discriminator.
Answer:
please find the attachment of a graph:
Explanation:
Description of the model:
Generalization is the method used here just for the EER model, which sweeping generalization is a way to identify the common characteristics of a sequence to create a common entity. This is an approach from the bottom up. Its verification, savings, and credit firms are extended to a higher-level object's account. So, the entity entities (Account) are the common traits of these bodies. As well as the specific qualities are the part of specialized entities (checks, savings, and loans). This EER model is shown via the subgroup and supertype notes. The Balance has calculated the distance, throughout the entity type entity are key patterns of the subgroup entities. The wood beaded includes Acct No, Balanced and Open Date. The key was its underliner Acct No. the very first key. CHECKING, SAVINGS, and LOAN are the subsection organizations of the Supertype Account.Its subtypes get the traits that are not normal. It Testing feature is the uncommon extra fee feature. Its SAVINGS post-type feature has the peculiar exchange rate feature. Its LOAN subgroup feature produces unusual interest in fixed payment characteristics.Enhanced Entity relationships[EER] represent the requirements and complexities of a complex database.
What is Enhanced Entity-relationship?Here, the account entity generalized into three entities and these are checking, savings, and loan.
Also, the common attribute the three of them have can be considered in the account entity which is common in them while the individual attributes must be specified under its own entity.

If the propagation delay through a full-adder (FA) is 150 nsec, what is the total propagation delay in nsec of an 8-bit ripple-carry adder
Answer:
270 nsec
Explanation:
Ripple-carry adder is a combination of multiple full-adders. It is relatively slow as each full-adder waits for the output of a previous full-adder for its input.
Formula to calculate the delay of a ripple-carry adder is;
= 2( n + 1 ) x D
delay in a full-adder = 150 nsec.
number of full-adders = number of ripple-carry bits = 8
= 2 ( 8 + 1 ) x 150
= 18 x 150
= 270 nsec

Technician A says that the last step in the diagnostic process is to verify the problem. Technician B says that the second step is to perform a thorough visual inspection. Who is correct
Answer:
The answer to this question is given below in the explanation section. However, the correct option is Technician B.
Explanation:
There are eight steps procedures to diagnose the engine.
Step 1 Verify the Problem
Step 2 Perform a Thorough Visual Inspection and Basic Tests
Step 3 Retrieve the Diagnostic Trouble Codes (DTCs)
Step 4 Check for Technical Service Bulletins (TSBs)
Step 5 Look Carefully at Scan Tool Data
Step 6 Narrow the Problem to a System or Cylinder
Step 7 Repair the Problem and Determine the Root Cause
Step 8 Verify the Repair and Clear Any Stored DTCs
So the correct technician is Technician B that says that the second step is to perform a thorough visual inspection.
Suppose one machine, A, executes a program with an average CPI of 1.9. Suppose another machine, B (with the same instruction set and an enhanced compiler), executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz. In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Answer:
the clock rate of the first machine need to be 1.7 GHz
Explanation:
Given:
CPI of A = 1.9
CPI of B = 1.1
machine, B executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz
To find:
In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Solution:
CPU execution time = Instruction Count * Cycles per Instruction/ clock rate
CPU execution time = (IC * CPI) / clock rate
(IC * CPI) (A) / clock rate(A) = (IC * CPI)B / clock rate(B)
(IC * 1.9) (A) / clock rate(A) = (IC * (1.1 * (1.0 - 0.20)))(B) / 800 * 10⁶ (B)
Notice that 0.20 is basically from 20% less instructions
(IC * 1.9) / clock rate = (IC * (1.1 * (1.0 - 0.20))) / 800 * 10⁶
(IC * 1.9) / clock rate = (IC*(1.1 * ( 0.8))/800 * 10⁶
(IC * 1.9) / clock rate = (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) / (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) (800 * 10⁶) / (IC * 0.88)
clock rate (A) = 1.9(800)(1000000) / 0.88
clock rate (A) = (1.9)(800000000) / 0.88
clock rate (A) = 1520000000 / 0.88
clock rate (A) = 1727272727.272727
clock rate (A) = 1.7 GHz
