Write a recursive function sumrecursive() to find the sum of first n natural numbers.

17 Jan 2019 by CPallini

The logic of the recursive (say) sum function is already given in the exercise text. Just the implementation is missing. Now what is exactly your problem with such implementation? If you are not able to write a recursive function, then have a look at this page: C++ Recursion - Recursive...

Overlooking the fact that the code you've provided won't compile at all ... Your function course() returns a struct, but that doesn't get assigned in the little bit of main() you've provided. Going back to basics - suppose we have a function f that takes an int as an argument, and returns an...

I know that char** is a pointer to pointer to a char and char* is a pointer to char, but I cannot understand the difference?

17 Feb 2023 by OriginalGriff

You allocate a block of memory (20 chars worth) and tell the system that that is a set of pointers to chars - because Str is a pointer to a pointer to a char. Which is effectively a pointer to a string. Think of Str as a array of pointers to...

It's called recursion, and its a fundamental algorithm. Think about factorials for a moment: N! = N * (N - 1)! for all values of N greater than zero - for all others N! is 1. So if N is 5, then N! can be expressed as 5! = 5 * (5 - 1)! == 5 *...

You cannot use a pointer as an array offset. If amp->rear is a pointer then you must use it as a pointer. It would make more sense to make it an integer value to use as an array index.
