如何投商

Question

我正在制作一个简单的计算器，其中列出了当有人输入两个整数时的所有内容。除了我似乎找不到那种演员的商，一切似乎都运作良好。

#define _CRT_SECURE_NO_WARNINGS
#include<stdio.h>
#include<stdlib.h>


#define SUM a + b
#define AVG (SUM) /(float) 2
#define SUBTRACTION a - b
#define MULTIPLICATION a * b 
#define QUOTIENT 
#define MODULUS a % b


void main()
{
    int a, b;
    printf("Enter two integers: ");
    scanf("%d%d", &a, &b);
    printf("\n\nThe Sum is %d\n", SUM);
    printf("The Difference is %d\n", SUBTRACTION);
    printf("The Multiplication is %d\n", MULTIPLICATION);
    printf("The Quotient is %d\n", QUOTIENT);
    printf("The Average is %0.2f\n", AVG);
    printf("The Modulus is %d\n", MODULUS);

    system("PAUSE");
}

Answer 1

此行

#define QUOTIENT 

应该是

#define QUOTIENT a / b

但应选中“除以零”
