《计算旅途时间》

【问题描述】2.2.7 输入2个整数time1和time2，表示火车的出发时间和到达时间,计算并输出旅途时间｡有效的时间范围是0000 ~2359(前两位表示小时,后两位表示分钟),不需要考虑出发时间晚于到达时间的情况｡

【样例输入输出】(括号内为说明文字)

Enter time1:712 (出发时间是7:12)

Enter time2:1411 (到达时间是14:11)

The train journey time is 6 hours 59 minutes

#include <stdio.h>
#include <stdlib.h>
int main(){
    int time1,time2,h1,h2,h3,m1,m2,m3;
    printf("Enter time1:");
    scanf("%d",&time1);
    printf("Enter time2:");
    scanf("%d",&time2);
    h1=time1/100;
    m1=time1%100;
    h2=time2/100;
    m2=time2%100;
    h3=h2-h1;
    m3=m2-m1;
    if(m3<0){
        m3=60+m3;
        h3=h3-1;
    }
    printf("The train journey time is %d hours %d minutes",h3,m3);
    return 0;
