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
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.
