How to convert hh:mm:ss to minutes in C++

Answer 1

#include <iostream>
#include <sstream>
#include <vector>

double hhmmsstominutes(const std::string& hhmmss) {
    std::vector<int> time;
    std::stringstream ss(hhmmss);
    std::string segment;

    while (getline(ss, segment, ':')) {
        time.push_back(stoi(segment));
    }

    return (time[0] * 60) + time[1] + (time[2] / 60.0);
}

int main() {
    std::cout << hhmmsstominutes("2:30:00") << std::endl;
    std::cout << hhmmsstominutes("2:35:30") << std::endl;
    std::cout << hhmmsstominutes("5:00:45") << std::endl;

    return 0;
}
