贴代码

include <stdio.h>
int main()
{
	int m, t, s,integer,remainder;
	scanf("%d%d%d", &m, &t, &s);
	if (t==0)
	{
		printf("%d",t);
	}
	if (s >= m * t)
	{
		printf("0");
	}
	else
	{
		integer = s / t;
		remainder = s % t;
		if (remainder != 0)
		{
			integer++;
		}
		printf("%d", m - integer);
	}
	return 0;
}

谢谢
