各位大佬麻烦帮忙看下

basketmn

#include<stdio.h>
int main(void)
{
        int i,j,a[2][26]={{'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'},
                                        {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}} ,b[256];
        for(i=0;(b[i]=getchar())!='\n';i++)
        if(a[0][i]==b[i]||a[0][i]+32==b[i])a[1][i]++;
        for(i=0;i<26;i++)printf("%c:%d\n",a[0][i],a[1][i]);
        return 0;
}

为什么这个代码输出结果不对
