Range of IF statements in C programming

if (5>=hour && hour<9){
    if(minute<7){
        printf("%d:00");
        return 0;}
    else if (8<=minute && minute<22){
        printf("%d:15",hour);
        return 0;}
    else if (22<=minute && minute<37){
        printf("%d:30",hour);
        return 0;}
    else if (38<=minute && minute<52){
        printf("%d:45",hour);
        return 0;}
    else{
        hour+=1;
        printf("%d:00");
        return 0;}

After compiling the value of the code is completely off, what is wrong with my statements? I can make the code longer and make it work but I am trying to simplify it.

EDIT: Basically I am trying to say if I input "5:01" output should be "5:00" and if my input is "5:22" output should be "5:30".

However my output values comes out to be "2686748:00"

Solution

  • The line printf("%d:00"); should be:

    printf("%d:00", hour);

    See if you can turn up your compiler warning level, modern compilers tend to be able to warn about this sort of mistake.
