编写一个C程序判断24小时制任意两个时间点直接的时间差

#include <stdio.h>

int main()
{
    int h1, m1, s1, h2, m2, s2, t1, t2, diff;

    // 输入第一个时间点的时分秒
    printf("Enter the first time (hh:mm:ss): ");
    scanf("%d:%d:%d", &h1, &m1, &s1);

    // 输入第二个时间点的时分秒
    printf("Enter the second time (hh:mm:ss): ");
    scanf("%d:%d:%d", &h2, &m2, &s2);

    // 将时分秒转换为秒数
    t1 = h1 * 3600 + m1 * 60 + s1;
    t2 = h2 * 3600 + m2 * 60 + s2;

    // 计算时间差
    diff = t2 - t1;

    // 输出时间差
    printf("The time difference is %d seconds.\n", diff);

    return 0;
}
