C++ 代码

#include<iostream>
#include <ctime>

using namespace std;

int main() {
    struct tm t1 = { 0 };
    struct tm t2 = { 0 };
    int seconds;
    int a,b,c,d;
    cin>>a>>b>>c>>d;
    t1.tm_hour=a;
    t1.tm_min=b;
    t2.tm_hour=c;
    t2.tm_min=d;

    seconds = difftime(mktime(&t2), mktime(&t1));//转换结构体为time_t,利用difftime,计算时间差
    if(seconds<=0){
        seconds+=86400;
    }
    int hour=seconds/3600;
    int min=(seconds%3600)/60;
    printf("O JOGO DUROU %d HORA(S) E %d MINUTO(S)\n",hour,min);
    return 0;
}
