if / else if / else, ternary ? : and switch work as in C.
for, while, do...while loops.
Range-based for loops over any container: for (int x : numbers).

Key Takeaways: C++ Conditions & Loops

Mastering C++ Conditions & Loops helps you write clean and reliable C++ code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

C++ Conditions & Loops Code Example

C++

#include <iostream>
#include <vector>

int main() {
    std::vector<int> marks = {72, 95, 58, 88};

    for (int m : marks) {
        if (m >= 85) std::cout << m << ": A\n";
        else if (m >= 60) std::cout << m << ": B\n";
        else std::cout << m << ": Fail\n";
    }

    int n = 1;
    while (n < 50) n *= 3;
    std::cout << "n = " << n << "\n";
    return 0;
}
