Is there anything wrong with my code?It's a program that coverts 24-h time format to 12-h time format, and only takes a four-digit integer as input.
ex. input = 0000 then output should be 00:00 a.m.
When I submit my code to schools online judge, it doesn't accept all inputs, but I can't find out the problem.
#include <stdio.h>int main(void){ int morning, hour, min; scanf("%02d%02d", &hour, &min); if (hour > 23 || min > 59) { return 1; } //check am pm if (hour >= 12) { morning = 1; if (hour > 12) { hour -= 12; } } else { morning = 0; } //print the result if (morning == 0) { printf("%02d:%02d a.m.", hour, min); } else { printf("%02d:%02d p.m.", hour, min); } return 0;}
