2. 题目内容

本题要求编写程序，计算2个正整数的和、差、积、商并输出。题目保证输入和输出全部在整型范围内。

输入格式:

输入在一行中给出2个正整数A和B。

输出格式:

在4行中按照格式“A 运算符 B = 结果”顺序输出和、差、积、商。

输入样例:

3 2

输出样例:

3 + 2 = 5
3 - 2 = 1
3 * 2 = 6
3 / 2 = 1

3. 源码参考

#include<iostream>

using namespace std;

int main()
{
    int a, b;

    cin >> a >> b;
    cout << a << " + " << b << " = " << a + b << endl;
    cout << a << " - " << b << " = " << a - b << endl;
    cout << a << " * " << b << " = " << a * b << endl;
    cout << a << " / " << b << " = " << a / b << endl;

    return 0;
}
