下列程序的功能是从输入的整数中，统计大于零的整数个数和小于零的整数个数。用输入0来结束输入，用i,j来放统计数，请填空完成程序。
void main()
{ n,i=0,j=0;
printf(“input a integer,0 for end\n”);
scanf(“%d”,&n);
while ( ) {
if(n>0) i= ;
else j=j+1;
}
printf(“i=%4d,j=%4d\n”,i,j);

aa_ca 回复 WhiteWing： 经典0分 n==0进入循环么 哥们
WhiteWing 回复 aa_ca： 看错啦
1. int
2.n！=0
int,n,i+1
代码优化
#include <stdio.h> void main(){ int n, i=0, j=0; int status; printf("input a integer, 0 for end\n"); status = scanf("%d", &n); while(status == 1){ if(n > 0) i = i+1; else if(n < 0) j=j+1; else if(n == 0) break; status = scanf("%d", &n); } printf("i=%4d,j=%4d\n", i, j); }
!n
Dlweikin 回复 Dlweikin： !n表示把自己变成与之相反的数，0变为非零数 while的退出条件是0
int n !=0 i+1
int i
&n...
