For Loops: Counting and Iterating

A for loop executes code repeatedly based on three parts: initialization (run once at start), condition (checked before each iteration), and increment (run after each iteration). Here, i starts at 0 and the loop runs while i is less than 5.

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

Breakdown

for (int i = 0; i < 5; i++)

Loop header: init i=0, check i<5, increment i++ after each iteration

std::cout << "Count: " << i << std::endl;

Outputs the current value of i each time the loop body executes
