always false

always true

in case cond1 is false

in case cond1 is true

Answer 1

d) in case cond1 is true

Explanation:

A while loop statement repeatedly executes a target statement as long as a given condition is true.

Syntax

The syntax of a while loop in C++ is −

while(condition) {
   statement(s);
}

Here, statement(s) may be a single statement or a block of statements. The condition may be any expression, and true if any non-zero value. The loop iterates while the condition is true.

When the condition becomes false, program control passes to the line immediately following the loop.

In this case, the while condition will be true only when cond1 is true.
