Post-Condition Iteration Logic

Snippet

Post-Condition Iteration Logic

The do-while loop guarantees at least one execution of the code block because the condition is evaluated after the body. This is useful for tasks like input validation where you need to run the logic before checking the state.

snippet.cpp

cpp

#include <iostream>
 
int main() {
    int count = 0;
    do {
        std::cout << "Execution cycle: " << count << std::endl;
        count++;
    } while (count < 0); // Executes at least once despite false condition
 
    return 0;
}

Breakdown

do { ... }

The body of the loop where instructions are executed immediately.

while (count < 0);

The termination condition checked after each iteration.
