学习C语言的第一天

晕了，我说第二个代码怎么测试总是输出0 0 原来是我输入的数太小了

#include<stdio.h>
int main()
{
	//int cm = 0;
	//scanf_s("%d", &cm);
	//int foot = cm / 30.48;
	//int inch = ((cm / 30.48) - foot) * 12;
	//printf("%d %d", foot ,inch);
	//return 0;
	int cm = 0;
	scanf_s("%d", &cm);
	int m = cm / 100;
	int foot = m/ 0.3048;
	int inch = ((m / 0.3048) - foot) * 12;
	printf("%d %d", foot ,inch);
	return 0;


}
