Simple Program for Function Template

To swap the numbers using the concept of the function template.

Simple Program Function Template Algorithm/Steps:

• STEP 1: Start the program.
• STEP 2: Declare the template class.
• STEP 3: Declare and define the functions to swap the values.
• STEP 4: Declare and define the functions to get the values.
• STEP 5: Read the values and call the corresponding functions.
• STEP6: Display the results.
• STEP 7: Stop the program.

Simple Program for Function Template

#include<iostream.h>
#include<conio.h>

template<class t>

void swap(t &x, t &y) {
    t temp = x;
    x = y;
    y = temp;
}

void fun(int a, int b, float c, float d) {
    cout << "\na and b before swaping :" << a << "\t" << b;
    swap(a, b);
    cout << "\na and b after swaping  :" << a << "\t" << b;
    cout << "\n\nc and d before swaping :" << c << "\t" << d;
    swap(c, d);
    cout << "\nc and d after swaping  :" << c << "\t" << d;
}

void main() {
    int a, b;
    float c, d;
    clrscr();
    cout << "Enter A,B values(integer):";
    cin >> a>>b;
    cout << "Enter C,D values(float):";
    cin >> c>>d;
    fun(a, b, c, d);
    getch();
}

Sample Output

Enter A, B values (integer): 10  20
Enter C, D values (float):    2.50  10.80
 
A and B before swapping: 10 20
A and B after    swapping:  20 10
 
C and D before swapping: 2.50  10.80
C and D after               swapping: 10.80  2.50

How It Works

This C++ program demonstrates Simple Program for Function Template. It first reads the required values as input, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Read the input values that the program will work with.
3. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
