段错误!

#include <stdio.h>
#define SEC_PER_MIN  60

int main(void)
{
    int sec,min;
    int left;
    sec  = 0;
    min  = 0;
    left = 0;

    printf("convert secs to min and secs\n");
    printf("Enter the number of secs(<=0 to quit):\n");

   
    scanf("%d",&sec);//这里为啥段错误？如何改？
    while( sec > 0 )
    {
        
        min  = sec / SEC_PER_MIN;
        left = sec % SEC_PER_MIN;
        printf("%d secs is %d mins and %sec.\n ", sec,min,left);
        printf("Enter next value (<=0 quit):\n");
        scanf("%d",&sec);
    }
   
    return 0;
}
调试后发现是scanf段错误，？？？

printf("%d secs is %d mins and %d sec.\n ", sec,min,left);

第22行：错误代码：      
printf("%d secs is %d mins and %sec.\n ", sec,min,left);
正确代码：
printf("%d secs is %d mins and %d.\n ", sec,min,left);
