#include<stdio.h>
#include<ctype.h>
int main()
{
    int a, b, c;
    a = b = c = 0;
    char ch;
    while (ch = getchar() != '#')
    {
        if (iswgraph(ch))
            a += 1;
        if (isblank(ch))
            b += 1;
        if ((ch != ' ')&& (ch != '\n'))
            c += 1;
        continue;
    }
    printf("空白符为:%d\n换行符为：%d\n其他字符为：%d", a, b, c);
    return 0;
}为什么出来是这样的
