算法-判断时间是否在时间表里边

#include <stdio.h>
#include <string.h>

int main() {
    char time_range[][20] = {
        "01:00:00 - 16:00:00",
        "17:00:00 - 18:00:00",
        "19:00:00 - 21:00:00",
        "22:00:00 - 00:00:00",
        "01:00:00 - 16:00:00",
    };
    
    
    int size = sizeof(time_range)/sizeof(time_range[0]);

    char start_time[9], end_time[9],compare_time[9];
    for(int i = 0; i < size ; i++) {
        strncpy(start_time, time_range[i], 8);
        strncpy(end_time, time_range[i] + 11, 8);
        strncpy(compare_time, time_range[i+1], 8);
        //判断前一个时间和后一个时间大小以及是否越界的问题，
        if(i+1<size && strcmp( end_time,compare_time)<0){ 
            printf("未记录时间为: %s - %s\n",end_time,compare_time);
        }
    }
   
    return 0;
