before starting, carefully study sort str(), stsrt(), s gets(), mod str(), and format(). you will use the code from all of these functions! the sort str() function will call the other functions, although you could call mod str() from s gets(). your end goal is to create a program that prints a class roll sheet in alphabetical order. the program prints out the roster like this... hatfield, heidi kaiser, russell lipshutz, howard penkert, dawn wright, elizabeth the user inputs the students' first name and last names separately but within one loop. the loop should end when the user presses enter on the first name without entering any text. upon completing entry of data, the output pictured above should display on stdout. first step: get all the files working from your sort str.c file with the following changes: you should be able to enter up to 10 student first names. also, change the input array to an appropriate size of 15 for the length of the first name. use a meaningful name for the storage of first names array. change prompts as needed. the loop should exit when the user presses enter when inputing the first name without adding any text. compile and make sure it works from main(). at this point, you should be able to enter and alphabetize a list of up to 10 first names! alphabetizing the first name is just a test!!! in the end, you will alphabetize the whole name string. make changes to convert the first name to all upper case using a function from mod str(). compile and test. add another array and get input for last name inside the loop for your first names. this last name array will also be an array of 10 elements but with room for up to 20 characters. again, do not use another loop! just add code to input the last name to the first loop. the program should now ask the user to input the student's first name and then last name in that order for each individual. then the program will loop to continue adding student names until the user presses enter on the student's first name. make sure the last name is converted to all caps. you do not need to alphabetize this array, but you may want to print it out to make sure everything is working just as a test. last step: combine last and first into an third array. you need to add the comma, so you may want to use sprintf() for this one. there are other ways. this code is most easily added to the first loop. you just had the user enter first and last names. so the current value of the subscript used for these arrays can be used to combine content and store in the third array. alphabetize this array (instead of the first name array) which means you need to send a different pointer to the stsrt() function. print out the end result. test that everything is working on this program.
The code that performs theabove function is given as follows.
#include <stdio.h>
#include<string.h>
void sort_str(char *str1, char *str2) {
int i, j;
char temp[20];
for(i = 0; str1[i] != '\0'; i+ +) {
for (j = i+ 1; str1[j] != '\0'; j++) {
if (str1[i] > str1[j]) {
strcpy(temp, str1 + i);
strcpy(str1 + i, str1 + j);
strcpy(str1 + j, temp);
}
}
}
for(i = 0; str2[i] != '\0'; i+ +) {
for (j = i+ 1; str2[j] != '\0'; j++) {
if (str2[i] > str2[j]) {
strcpy(temp, str2 + i);
strcpy(str2 + i, str2 + j);
strcpy(str2 + j, temp);
}
}
}
}
void mod_str(char *str) {
int i;
for (i =0; str[i] != '\0'; i++) {
if (str[i] > = 'a' && str[i] <= 'z') {
str[i] -= 'a';
str[i] += 'A';
}
}
}
void format(char *str1,char *str2, char *str3) {
sprintf(str3, "%s, %s", str1, str2);
}
int main() {
char first_name[15];
char last_name[20];
char full_name[35];
int i, count = 0;
printf("Enter the first name and last name of the student (press enter on first name without entering any text to quit):\n");
while (1) {
printf("First name: ");
fgets(first_name, 15, stdin);
if (first_name[0] == '\n'){
break;
}
printf("Last name: ");
fgets(last_name, 20, stdin);
mod_str(first_name);
mod_str(last_name);
format (first_name, last_name,full_name);
sort_str(full_name,full_name + strlen(full_name));
print f("%s\n", full_name) ;
count++;
}
printf("The class roll sheet in alphabetical order is:\n");
for (i =0; i < count; i++) {
printf("%s\n", full_name + i* strlen(full_name));
}
return 0;
}
How does this work ?This program works by first asking the userto enter the firstname and last name of each student.The first name is converted to all uppercase letters using the mod_str() function.
The last name is also converted to all uppercase letters.The full name is then created by combining the first and last names,with a comma in between.
The full name is then sorted using the sort_str( ) function. The sorted full name is then printed to the console. The program repeats this process until the user presses enter on the first name without entering any text.
When the user presses enter, the program prints the class roll sheet in alphabetical order.

ceiling joists span the narrow dimension of the building from
Ceiling joists span the narrow dimension of a building from one wall to the opposite wall. They provide structural support for the ceiling and help distribute the weight of the roof and any loads from the floor above.
Ceiling joists also known as roof joists are structural elements that span the narrow dimension of a building from wall to wall or from support to support. They are typically placed at regular intervals along the length of the building and run perpendicular to the roof rafters or trusses. The primary function of ceiling joists is to support the weight of the ceiling and any loads that may be imposed on it, such as insulation or light fixtures. The span of ceiling joists depends on a variety of factors, including the weight of the ceiling materials, the spacing of the joists, and the type and size of the building materials used. It is important to consult a qualified structural engineer or builder to determine the appropriate size and spacing of ceiling joists for your particular building project.
