- in c++ Given the string "An elephant." Store it in a char pointer Print on one line the letter on the index 0. Then print the letter on index 8. Update the pointer so that it prints all the alternate letters as follows: A lpatWrite in C++ Alice is trying to monitor how much time she spends studying per week. She going through her logs, and wants to figure out which week she studied the least, her total time spent studying, and her average time spent studying per week. To help Alice work towards this goal, write three functions: min(), total(), and average(). All three functions take two parameters: an array of doubles and the number of elements in the array. Then, they make the following computations: min() - returns the minimum value in the array sum() - returns the sum of all the values in the array average() - returns the average of all the values in the array You may assume that the array will be non-empty. Function specifications: Function 1: Finding the minimum hours studied Name: min() Parameters (Your function should accept these parameters IN THIS ORDER): arr double: The input array containing Alice's study hours per week arr_size int: The number of elements stored in the array Return Value:…Do void and NULL pointers differ?

Take input a sorted array from the user. Display the char array on console such that each row has only five elements separated by spaces. Then, you are required to then take a char x from the user and use binary search to search for element x in the array. Display the index of the element on the console. Also display two elements before and after the element x. Note: Don't use functions and strings.8. using c++, Write a function method that determines the mean of all the values in an array of integers. Your mean function should call a separate function that you write that determines the sum. Don’t use built-in sum or mean gadgets, but roll your own.

- This is my c++ homework, and I get a question about the following code written by the professor. I did not understand the "p++" in the code, and I do not understand why we have to write this. I think we can just simply assign *pn=n then will be okay? why we write p++? Please explain to me, thank you. // more pointers #include <iostream> using namespace std; int main () { int numbers[5]; int * p; p = numbers; *p = 10; p++; *p = 20; p = &numbers[2]; *p = 30; p = numbers + 3; *p = 40; p = numbers; *(p+4) = 50; for (int n=0; n<5; n++) cout << numbers[n] << ", "; return 0; }Write in C++ When you're processing data, it’s useful to break up a text string into pieces using a delimiter.
