To perform math operations in C++, you can use the math library, which provides various functions for mathematical calculations. Here's an example using the pow() function, which calculates the power of a number:

#include <iostream>
#include <cmath>

int main() {
    double base = 2.0;
    double exponent = 3.0;
    double result = pow(base, exponent);

    std::cout << "The result is: " << result << std::endl;

    return 0;
}

Explanation:

1. Include the necessary libraries:

#include <iostream>
#include <cmath>

The iostream library allows us to use the input/output streams, while the cmath library provides mathematical functions.

1. Declare the variables:

double base = 2.0;
double exponent = 3.0;

Here, we declare two variables base and exponent and assign them the values 2.0 and 3.0, respectively.

1. Calculate the result:

double result = pow(base, exponent);

The pow() function from the cmath library takes two arguments: the base and the exponent. It calculates the power of the base raised to the exponent and returns the result. We store the result in the result variable.

1. Print the result:

std::cout << "The result is: " << result << std::endl;

Using the cout object from the iostream library, we display the result on the console.

1. Return 0:

return 0;

In the main() function, the return 0; statement indicates that the program has executed successfully and can be terminated.

That's how you can perform math operations and explain each step using the pow() function in C++.
