使用’-‘运算符将两个数字相加

任务是使用’-‘运算符将两个数字相加。

例子：

Input : 2 3
Output : 5

Input : 10 20
Output : 30

这个想法很简单，我们从a减去-b。

C++

// CPP program to add two numbers using
// - operator.
#include 
using namespace std;
 
// function to add two numbers.
int add(int a, int b)
{
    return a - (-b);
}
 
// Driver code
int main()
{
    int a = 2, b = 3;
    cout << add(a, b) << endl;
    return 0;
}

Java

// Java program to add
// two numbers using
// - operator.
import java.io.*;
 
class GFG
{
     
// function to add two numbers.
static int add(int a, int b)
{
    return a - (-b);
}
 
// Driver code
public static void main (String[] args)
{
    int a = 2, b = 3;
    System.out.print(add(a, b));
}
}
