C :

#include <stdio.h>
void main()
{
	int a ,b,c,d,e,f,g,h,min;
	scanf("%d %d %d %d",&a, &b ,&c ,&d);
	g=a*60+b;h=c*60+d;
	min=h-g;
	e=min/60;f=min-e*60;
	printf("%d %d",e,f);
	

	
	
	
} 
 

C++ :

#include <iostream>
using namespace std;

int main(){
	int a,b,c,d;
	cin>>a>>b>>c>>d;
	int t1 = a * 60 + b;
	int t2 = c * 60 + d;
	
	int t = t2 - t1;
	cout<<t / 60<<" "<<t % 60<<endl;
}

Python :

a,b,c,d=map(int,input().split())
if d>=b:
    f=d-b
    e=c-a
elif d<b:
    f=d+60-b
    e=c-1-a
print(e,f)
