Answer 1

你题目的解答代码如下：

#include <stdio.h>

int countdigit(int number, int digit)
{
    int count = 0;
    do {
        if (number%10==digit)
            count++;
        number /= 10;

    } while (number>0);
    return count;
}

int main() {
    int n,d;
    scanf("%d%d", &n, &d);
    printf("%d", countdigit(n, d));
    return 0;
}

如有帮助，望采纳！谢谢!
