Solution

#include <print>

double to_fahrenheit(double c) {
    return c * 9.0 / 5 + 32;
}

int main() {
    for (double c : {0.0, 37.0, 100.0}) {
        std::println("{:.1f} C = {:.1f} F", c, to_fahrenheit(c));
    }
}

How it works

• 9.0 / 5 is a decimal division. 9 / 5 would be 1 (integer division).
• {:.1f} prints one digit after the point.
