What is the purpose of the pow function in C++?

The pow function in C++ is used to calculate the power of a number. It takes two parameters, the first being the base and the second being the exponent. The function returns the result of raising the base to the exponent.

For example, to calculate the third power of 2, you can use pow(2, 3) which will return 8. Similarly, pow(3, 2) will return 9, and pow(4, 0.5) will return 2.
