compute the angle between hour hand and minute hand
input: hh:mm
output: out a float that means the angle of inferior arc
eg:
03:00
14:45
output:
90.00
172.50
#include <stdio.h>
int main(int args, char* argv[]) {
int h, m;
scanf("%d:%d",&h,&m);
if (h < 0 || h > 24 || m > 60 || m < 0) {
return -1;
}
h %= 12;
float hr = (h + (m/60.0f)) * 5;
float r = (hr - m) ? (m - hr) * 6 : (hr - m) * 6;
printf("%.2f", (360.00f - r) > 180.00f ? (r): (360.00f - r));
return 0;
}
