Do-While Loop: Guaranteed First Execution

Snippet

Do-While Loop: Guaranteed First Execution

The do-while loop always executes its body at least once before checking the condition. Unlike a regular while loop that checks first, do-while guarantees the code runs once regardless of whether the condition is true or false initially.

snippet.cpp
cpp
#include <iostream>
using namespace std;
 
int main() {
    int count = 0;
    
    do {
        cout << "Count: " << count << endl;
        count++;
    } while (count < 3);
    
    return 0;
}

Breakdown

do { ... } while (condition);

Body executes first, then condition is checked; semicolon required after while
