how to return two different random number in unity code example

Example 1: add two numbers in c++

#include <iostream>
using namespace std;

//function declaration
int addition(int a,int b);

int main()
{
	int a,b;	//to store numbers
	int add;	//to store addition 
	
	//read numbers
	cout<<"Enter first number: ";
	cin>>a;
	cout<<"Enter second number: ";
	cin>>b;
	
	//call function
	add=addition(a,b);
	
	//print addition
	cout<<"Addition is: "<<add<<endl;
	
	return 0;
}

//function definition
int addition(int a,int b)
{
	return (a+b);
}

Example 2: how to add a number after each number in an array with a for loop in C++

#include<iostream>
	using namespace std;

	int main()
	{
		int a[4];
		int i;

		for ( i = 0; i < 4; i++ )
			a[i] = 0;
		for ( i = 0; i < 4; i++ )
			cout << a[i] << '\n';
		return 0;
	}
