介绍C程设计的一典型案例：例如编写一些小游戏

#include<stdio.h>
int even(int x);
int main(void)
{
	int x,y;
	y=0;
	printf("Input integers:");
	while(1)
	{
		scanf("%d",&x);
		if(x<=0)
			break;
		if(even(x)==0)
			y=y+x;
	}
	printf("The sum of the odd numbers is %d\n",y);
	return 0;
}
int even(int x)
{
	int z;
	z=0;
	if(x%2==0)
		z=1;
	return z;
}
