While Loop: Repeating Until a Condition is False

While Loop: Repeating Until a Condition is False

A while loop repeats code as long as its condition is true. The condition is checked BEFORE each iteration. If the condition is initially false, the loop body never executes. Always ensure the condition eventually becomes false to avoid an infinite loop.

snippet.cpp
cpp
#include <iostream>
 
int main() {
    int count = 1;
    
    while (count <= 5) {
        std::cout << "Count is: " << count << std::endl;
        count = count + 1;
    }
    
    return 0;
}

Breakdown

int count = 1;

Initializes a counter variable to 1 before the loop starts

while (count <= 5) {

Checks if count is less than or equal to 5; loop continues while true

std::cout << "Count is: " << count << std::endl;

Prints current value of count each iteration

count = count + 1;

Increments count by 1 to eventually end the loop
