C语言编程：输入整数a和b，如果a能被b整除，就输出算式和商，否则输出算式、整数商和余数。

#include <stdio.h>

int main()
{
    int a, b, quotient, remainder;

    printf("请输入两个整数a和b：\n");
    scanf("%d%d", &a, &b);

    if (a % b == 0) {
        quotient = a / b;
        printf("%d/%d=%d\n", a, b, quotient);
    } else {
        quotient = a / b;
        remainder = a % b;
        printf("%d/%d=%d...%d\n", a, b, quotient, remainder);
    }

    return 0;
}
