c program to calculate power of number using recursion

Recursion (recursion) in computer science refers to a method of solving a problem by repeatedly decomposing the problem into sub-problems of similar problems. Can greatly reduce the amount of code. The ability to recursion is to define an infinite

We know that the multiplication of two n-digit integers, if the regularAlgorithmThe time complexity is O (n2 ). However, using the fast Fourier transformation, the time complexity can be reduced to O (n logn ).   Assume that we want to calculate

/* It is recommended to a friend who wants to learn C ++ a simple but complete roadmap for learning C ++: C ++ primer-> C ++ standard library-> Objective C ++-> Objective STL-> exploring C ++ object models C program common algorithm source

1. Overview In the past decade, object-oriented programming has become popular. As a result, in university education, teachers only teach us two programming models, process-oriented and object-oriented. I don't know. Before the emergence of

1. What is an algorithm?Algorithms are a series of clear instructions for solving problems, that is, they can obtain the required output within a limited period of time for certain standard input. Algorithms often contain repeated steps and

In the past decade or so, object-oriented programming has been a big line. So that in college education, teachers will only teach us two programming models, process-oriented and object-oriented.It is not known that, before object-oriented generation,

Recursive invocation of the 5.1.5 functionIn a function call, we usually call another function in one function to accomplish some of these functions. For example, we call the Powersum () function in main () main function to calculate the sum of
