C语言输出各种字符的数量

#include<stdio.h>
#include<stdlib.h>
int main()
{
    int q = 0, w = 0, e = 0, r = 0;
    char c;
    while (scanf_s("%c",&c) != EOF && c != '\n')
    {
        if ((c >= 'a' && c <= 'z' )|| (c >= 'A' && c <= 'Z'))
            q++;
        else if (c == ' ')
            w++;
        else if(c >= '0' && c <= '9')
            e++;
        else
            r++;
    }
    printf("字母%d\n空格%d\n数字%d\n其它%d\n", q, w, e, r);
    return 0;
}

改成c=getchar&&c!='\n'
