cpp template

#include <iostream>

template <typename T>
T add(T a, T b) {
    return a + b;
}

int main() {
    int x = 5, y = 10;
    float p = 3.5, q = 2.5;

    std::cout << "Adding integers: " << add(x, y) << std::endl;
    std::cout << "Adding floats: " << add(p, q) << std::endl;

    return 0;
}

This C++ code demonstrates the use of templates.

1. Header Inclusion: The code includes the necessary header file <iostream> for input and output operations.

2. Template Function: A template function add is declared using the template keyword and the <typename T> syntax to define a generic type T. This function takes two parameters of type T and returns their sum.

3. Main Function: Inside the main() function, variables x, y (of type int), p, q (of type float) are declared and initialized with values.

4. Function Calls: The add function is called twice:

5. add(x, y) adds two integers and prints the result.

6. add(p, q) adds two floats and prints the result.

7. Output: The std::cout statements display the results of the addition operations on the console.

8. Return: The main() function returns 0, indicating successful execution. ```
