两个数相加求和 c++

#include

using namespace std;

int main()

{

int firstNumber,secondNumber,sumOfTwoNumbers;

cout << "输入两个整数：";
cin >> firstNumber >> secondNumber;

//相加求和
sumOfTwoNumbers = firstNumber + secondNumber;

//输出
cout << firstNumber << "+" << secondNumber << "=" << sumOfTwoNumbers;
return 0;
