Operators

Arithmetic (+ - * /), comparison (== != > <), and logical (&& || !) operators work as in most C-family languages.

Example: a boolean expression and a ternary for output

#include <iostream>
using namespace std;

int main() {
    int score = 85;
    bool passed = score >= 50 && score <= 100;
    cout << "Passed: " << (passed ? "true" : "false") << endl;
    return 0;
}

Passed: true

C++ doesn't have a genuine boolean-to-string conversion built in the way some languages do, printing passed directly would show 1 or 0, not the word "true" or "false", so the ternary (passed ? "true" : "false") is a common, idiomatic way to print a readable label instead.
