C++ - Programming Language

This course covers the basics of programming in C++.

an example of a function in C++ that calculates the exponent of a number:

#include <iostream>

double power(double base, int exponent) {
    double result = 1;
    for (int i = 0; i < exponent; i++) {
        result *= base;
    }
    return result;
}

int main() {
    std::cout << power(2, 4) << std::endl; // prints 16
    std::cout << power(3, 3) << std::endl; // prints 27
    return 0;
}

In this example, the power function takes two parameters: base and exponent. It initializes a variable result to 1, and then enters a for loop that multiplies result by base for exponent number of times. After the loop completes, the function returns the final value of result.

In the main function, the program calls the power function twice with different parameters, and prints the results to the console using std::cout. The program then returns 0 to indicate successful execution.

You can customize the function to handle negative exponents, zero exponent, or any other special cases you need to consider for your specific use case.
