请各位前辈帮我看一下这段代码为什么解决不了这个字符串问题呢，自我感觉良好

Question

#include<stdio.h>
int main(void){
    int n;
    char x;
    scanf("%d",&n);
    while(n--){
        int i=0;
        while(x=getchar()!='\n'){
            if('0'<=x&&x<='9')
                i++;
        }
        printf ("%d\n",i);
    }
    return 0;
}

Answer 1

修改一下

#include<stdio.h>
int main(void){
    int n = 0, i = 0, j = 0;
    char x[100];
    cin >> n;
    while (n--)
    {
        cin >> x;
        j = i = 0;
        while (x[j] != '\0')if ('0' <= x[j] && x[j++] <= '9')++i;
        printf_s("%d\n", i);
    }
}

while((x=getchar())!='\n')这样修改一下即可
