public:
//generic function

void add(T a,T b)
{
T ans;
ans=a+b;
cout<<"Addition of "<<a<<" and "<<b<<" is "<<ans<<endl;
}
  
};

int main()
{

//declaring class that receives integer data
addition<int> obj;

//declaring class that receives float data
addition<float> obj2;
obj.add(10,20);//class receives integer data as input and outputs integer value as answer
obj2.add(15.5,10.2);//same class here receives float data as input and output float value as answer
return 0;
}
