有疑问求大佬解答

不是清空，是重新初始化a[i]，如 a[i]=0

#include<stdio.h>
#include <strings.h>

int main()
{   
    int a[100];
    long m,n,i;
    int x,A;
    int j=0;
    while(scanf("%ld %ld",&m,&n)!=EOF)
    {   
        if(m>0)
            x=1;
        else   
            {x=0; m=-m; printf("-");}
        
        for(i=0;i<100;i++)
        {
            A=m/n;
            a[i]=m%n;
            j++;
            m=A;
            if(A==0) break;
        }
        
        for(i=j-1;i>=0;i--)
        {
            if(a[i]<10)
                printf("%d",a[i]);
            else
                printf("%c",a[i]+'A'-10);
        }
        
        j = 0;
        bzero(a,400);
        
        printf("\n");
    }
}  
使用个bzero函数，将j值清零，不然j之一直增
