Question

How to convert meters to yards and vice versa in C++

Answer 1

#include <iostream>
#include <iomanip>

constexpr double METER_TO_YARD = 1.0936133;
constexpr double YARD_TO_METER = 0.9144;

double metersToYards(double meters) {
    return meters * METER_TO_YARD;
}

double yardsToMeters(double yards) {
    return yards * YARD_TO_METER;
}

int main() {
    double m = 10.0;
    double y = metersToYards(m);

    std::cout << std::fixed << std::setprecision(1);
    std::cout << m << " meters = " << y << " yards\n";

    double y2 = 10.0;
    double m2 = yardsToMeters(y2);

    std::cout << y2 << " yards = " << m2 << " meters\n";
}

run:

10.0 meters = 10.9 yards
10.0 yards = 9.1 meters
