利用数组处理批量数据

有一篇文章，共3行文字，每行有10个字符。要求分别统计出其中英文大写字母、空格、英文小写字母、数字以及其他字符的个数

供参考：

#include<stdio.h>
int main()
{
    char ch;
    int  lower = 0, upper = 0, dight = 0, blank = 0, other = 0;
    while ((ch = getchar()) != EOF)
    {
        if (ch >= 'a' && ch <= 'z')
            lower++;
        else if (ch >= 'A' && ch <= 'Z')
            upper++;
        else if (ch >= '0' && ch <= '9')
            dight++;
        else if (ch == ' ')
            blank++;
        else
            other++;
    }
    printf("upper = %d,blank = %d,lower = %d,digit = %d,other = %d",
                                  upper, blank, lower, dight, other);
    return  0;
}
