Loops

Loops repeat a block while a counter changes.

loops.cpp

#include <iostream>

int main() {
    int limit = ;
    int total = 0;

    for (int number = 1; number <= limit; number++) {
        total += number;
    }

    std::cout << "limit=" << limit << std::endl;
    std::cout << "total=" << total << std::endl;
    return 0;
}

#include <iostream>

int main() {
    int limit = ;
    int total = 0;

    for (int number = 1; number <= limit; number++) {
        total += number;
    }

    std::cout << "limit=" << limit << std::endl;
    std::cout << "total=" << total << std::endl;
    return 0;
}

for loop A `for` loop can initialize a counter, test a condition, and update the counter after each pass.
