c++ template

#include <iostream>

// Step 1: Define a template function
template <typename T>
T add(T a, T b) {
    return a + b;
}

int main() {
    // Step 2: Instantiate the template function with specific types
    int result_int = add(3, 5);
    double result_double = add(2.5, 4.7);

    // Step 3: Display the results
    std::cout << "Integer Addition Result: " << result_int << std::endl;
    std::cout << "Double Addition Result: " << result_double << std::endl;

    return 0;
}

Explanation: 1. Include the necessary header file (#include <iostream>) for input/output operations.

1. Define a template function using the template keyword followed by the template parameter <typename T>. This function, named add, takes two parameters of the same type T and returns their sum.

2. In the main function:

3. Instantiate the template function with specific types (int and double).

4. Store the results of the function calls in variables (result_int and result_double).

5. Display the results using std::cout and the << operator.

6. The program returns 0 to indicate successful execution.
