从键盘上输入任意一些整数，统计正数的个数，负数的个数，以及零的个数

#include <stdio.h>
int main(){
int numPos = 0, numNeg = 0, numZeros = 0, num, in;
printf("Please key in the number of integers:\n");
scanf("%d", &num);
while(num > 0){
scanf("%d",&in);
if(in > 0){
numPos++;
}
else if(in < 0){
numNeg++;
}
else numZeros++;
num--;
}
printf("There are %d positive integers.\n", numPos);
printf("There are %d negative integers.\n", numNeg);
printf("There are %d 0s.\n", numZeros);
return 0;
}

borland C版本5.5编译通过。
