Write a program to swap two variable values using functioncall by value by MistarAV

#include<iostream>
using namespace std;
void swap(int,int);
int main()
{
int num1,num2;
cout<<"\n Enter First Number : ";
cin>>num1;
cout<<"\n Enter Second Number : ";
cin>>num2;
cout<<"\n Before Swapping the Value : \n"<<" "<<num1<<"\t"<<num2<<"\n";
swap(num1,num2);
cout<<"\n Outside Function After Swapping the Value : \n"<<"
"<<num1<<"\t"<<num2<<"\n";
}
void swap(int num1,int num2)
{
int num3;
num3=num1;
num1=num2;
num2=num3;
cout<<"\n Inside Function After Swapping the Value : \n"<<" "<<num1<<"\t"<<num2;
}

Output

Enter First Number : 2
Enter Second Number : 8
Before Swapping the Value :
2 8
Inside Function After Swapping the Value :
8 2
Outside Function After Swapping the Value :
2 8
