VS2015 c语言 错误1：_main已经在 文件夹名.obj 中定义 错误2：一个或多个多重定义的符号

#include<stdio.h>

int main()
{
int hour1, min1;
int hour2, min2;

printf("please make sure that the time you put in first is shorter");
scanf_s("%d %d", &hour1, &min1);
scanf_s("%d %d", &hour2, &min2);

int t1 = hour1 * 60 + min1;
int t2 = hour2 * 60 + min2;

int t = t2 - t1;

printf("the minus is %d hours %d min", t / 60, t % 60);

getchar();
return 0;
}
