Help with my C homework

Hi guys, need help with my homework. It is neccesary to create a function double stepen(double x) that works as follows: every time the function is called with a given number x, it returns the next power of number x, so it returns x^1 for the first time, then x^2 , X^3, x^4, etc. However, when called with another number x, the power is reset to 1.
Use this function to create a function with the following prototype: void stepenuj_niz (double A [], int s [], int length) The function receives a series of real numbers A and a series of natural numbers s that are the same length, and then each member of series A is powered with the exponent given in the corresponding member of string s. You must use the first function in the second function.

You cannot simply post your assignment and wait for someone to do your homework for you. Give it a go yourself and then post the difficulties you encountered. How else do you think you are going to learn? Will you be taking Internet with you to the exam?

Remember static variables taught to you in class? No?

> corresponding member of string s

Don't you mean integer array s?

Wow, what a horrible function. Oh well, I guess you have to do what the teacher wants but hopefully your teacher also explains why it's silly to write stepen() to behave like that
