后面乱码出现的原因是什么? 什么情况下还会出现这种类似的乱码??
#include <conio.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int fun(int score[],int m, int below[])
{
int i,sum=0,count=0,j,k=0;
float av=0.0;
for(i=0;i<m;i++)
{
sum+=score[i];
count++;
}
av=sum/m;
for(j=0;j<m;j++)
{
if(score[j]<av)
{
below[k++]=score[j];
}
}
return count;
}
void main()
{
FILE *wf;
int i, n, below[9];
int score[9]={10,20,30,40,50,60,70,80,90};
system("CLS");
n=fun(score, 9, below);
printf("\nBelow the average score are: ");
for(i=0;i<n;i++)
printf("%d ",below[i]);
