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

Answer 1

#include <stdio.h>
#include <stdlib.h>

double hhmmsstominutes(const char *hhmmss) {
    int hours, minutes, seconds;
    
    // Parse the HH:MM:SS string
    sscanf(hhmmss, "%d:%d:%d", &hours, &minutes, &seconds);

    // Convert to total minutes
    return (hours * 60) + minutes + (seconds / 60.0);
}

int main() {
    printf("%.2f\n", hhmmsstominutes("2:30:00"));
    printf("%.2f\n", hhmmsstominutes("2:35:30"));
    printf("%.2f\n", hhmmsstominutes("5:00:45"));

    return 0;
}
