which is true about the conditional of an if statement? group of answer choices it must always evaluate to a boolean result it should always evaluate to true it should always involve exact comparisons, when using floating-point numbers it should never involve integer comparisons
The condition in an if statement using relational operators will evaluate to a Boolean result.
What is Boolean result?
A logical assertion that can only be TRUE or FALSE is known as a Boolean expression. As long as both sides of the expression have the same fundamental data type, boolean expressions can compare data of any kind. Data can be tested to check if it is more than, less than, or equal to other data.
Boolean information, like the following, can make up a Boolean expression:
CONTEXT values (YES and NO, and their synonyms, ON and OFF, and TRUE and FALSE)
BOOLEAN formulae or variables
functions that produce BOOLEAN outcomes
Comparison operators calculate BOOLEAN values.
Assume, for instance, that the following Boolean expression appears in your code.
genuine GT 20000
Comparison and logical operators are displayed in Table 2-9, "Comparison and Logical Operators." Each operator has a priority that establishes the order in which it will be evaluated. Unless parentheses indicate a different evaluation order, operators with equal priorities are evaluated from left to right. When the truth value has been determined, the evaluation is stopped. For instance, because the first clause establishes if the entire statement is true, the TOTAL function is never used in the following expression.

You should use an outer loop that runs the inner loop (the one which computer the mean) a total of 10 times, printing out the 10 results, one per line.
Answer:

var Summ : integer;
Num : integer;
Sa : real;
begin
Num := 0;
for var j := 1 to 10 do

Summ := 0;
for var i:= 1 to N do
Summ := Summ + Random (1001);
Sa := Summ / N;
Write (' Sa = ', Sa);

An ordered linear series of things can be stored in an abstract data type called a stack. A stack is a last in, first out (LIFO) structure as opposed to a queue.
Is stack LIFO or FIFO?
The main distinction between stack and queue data structures is that while queue uses a FIFO data structure type, stack uses LIFO. Last In First Out is referred to as LIFO. It implies that the last element is processed first when data is added to a stack. On the other hand, FIFO stands for First In First Out.
A stack is a collection of identically typed components. We can only add and remove elements from one end of a stack.
