Hai guys My name Eddy, I'm HND Software Engineering at TATI, Malaysia, this is my 1st year of study, i need help ! somene can change below source code to templete by using C++ source code please help ... this is the source code:
-----------------------------------------------------------------------------------

#include<iostream>
using namespace std;
class calculator
{
private:
    int x,y;

public:
    calculator(int=1,int=1);//contructor
    ~calculator();//destructor

    int mc();
    int ac();
    int sc();
    int dc();
    void calc(char);

}; //end of class declaration


//contructor defination

calculator::calculator(int a,int b) //destructor
{x=a;y=b;}
calculator::~calculator() //destructor
{}

int calculator::mc()
{
    cout<<"\n\n"<<x<<"time"<<y<<"equals";
    return(x*y);
}
int calculator::ac()
{
    cout<<"\n\n"<<x<<"time"<<y<<"equals";
    return(x+y);
}
int calculator::sc()
{
    cout<<"\n\n"<<x<<"time"<<y<<"equals";
    return(x-y);
}
int calculator::dc()
{
    cout<<"\n\n"<<x<<"time"<<y<<"equals";
    return(x/y);
}
void calculator::calc(char choice)
{
    //int on,tw;
        if (choice == '+') //This whole block checks what the user wants to calculate, and refers to the proper routine to calculate it.
    {
        cout<<"You selected "<<choice<<". Please enter two numbers,";
        cout<<"that you want to add."<<endl;//print instructions for the user
        cin>>x;//Get the value of variable on
        cin>>y;//Get the value of variable tw
        cout<<ac()<<"\n\n\n\aThanks for using my calculator!";//Print a thank you message
    }
    else if (choice =='-')
    {
        cout<<"You selected "<<choice<<". Please enter two numbers,\nsepperated by spaces, that you want to subtract."<<endl;
        cin>>x;
        cin>>y;
        cout<<sc()<<"\n\n\n\aThanks for using my calculator!";
    }
    else if (choice =='*')
    {
        cout<<"You selected "<<choice<<". Please enter two numbers,\nsepperated by spaces, that you want to multiply."<<endl;
        cin>>x;
        cin>>y;
        cout<<mc()<<"\n\n\n\aThanks for using my calculator!";
    }
    else if (choice =='/')
    {
        cout<<"You selected "<<choice<<". Please enter two numbers,\nsepperated by spaces, that you want to divide."<<endl;
        cin>>x;
        cin>>y;
        cout<<dc()<<"\n\n\n\aThanks for using my calculator";
    }
    else
    {
        cout<<"\nPlease reenter that value.\n\a";
        cin>>choice;
        calc(choice);
    }
}
int main()
{

    calculator object(5,6);
    char choice;
    while (choice != 'e')
    {
        cout<<"\nPlease enter +,-,*, or / and then two numbers,\nsepperated by spaces, that you wish to\nadd,subtract,multiply,or divide.\nType e and press enter to exit.";
        cin>>choice;
        if (choice != 'e')
        {
            object.calc(choice);
        }        
    }
    return 0;
}

Please someone help me convert to templete...please... as soon as posible..

Hello, we don't do homework but if you had a specific question about templates feel free to ask. :)

You have a lot of repetitive code there that could go outside of the if statement . . .

I don't understand your question in post #3
