Practical 30

#include <iostream>
using namespace std;

template <class Gajjar> 

void swapab(Gajjar &a, Gajjar &b)
{

  Gajjar temp;
  temp = a;
  a = b;
  b = temp;
}

int main()
{
  int i,j; 

  cout<<"\nEnter int i and j:";

  cin>>i>>j;

  cout<<"\nBefore Swapping With Template: int i & j:"<<i<<" "<<j;

  swapab(i,j);

  cout<<"\nAfter swapping with template int i & j:"<<i<<" "<<j;

  float a,b;

  cout<<"\nEnter float a and b:";

  cin>>a>>b;

  cout<<"\nBefore Swapping With Template: float a & b:"<<a<<" "<<b;

  swapab(a,b); 

  cout<<"\nAfter swapping with template float a & b:"<<a<<" "<<b;    

 return 0;
