(Function Template swap_value) Write a program that uses a function template called swap_value to swap the value of two arguments. Test the program using integer, character and floating point number arguments.

The input consists of n (0<n<100) samples.
Each sample consists of three lines.
The first line of each sample consists of two integers(range from 0 to 100)
The second line of each sample consists of two char.
The third line of each sample consists of two doubles(range from 0 to 100)
The last line of input consists of Int(-1).

The main function is provided, you only need to complete the Function Template swap_value:

#include <iostream>
using namespace std;

// ToDo function template swap_value

int main()
{
    int int1 = 0;
    int int2 = 0; 
    char char1 = ' ';
    char char2 = ' ';     
    double double1 = 0; 
    double double2 = 0;     

    while(true){
        cin>>int1;
        if(int1==-1)
            break;
        cin>>int2;
        swap_value(int1, int2);
        cout<<int1 << " "<<int2<<endl;

        cin >> char1 >> char2;
        swap_value(char1,char2);
        cout << char1 << " " << char2 << endl;

        cin >> double1 >> double2;
        swap_value(double1,double2);
        cout << double1 << " " << double2 << endl;

        cout<<endl;
    }

}
