Programming language C Please go through this carefully. Needs function void add(int *a1, int n, int *a2) Write a program addition.c that reads in an array (a1) of numbers, and creates a new array (a2) of numbers such that the first and last numbers of a1 are added and stored as the first number, the second and second-to-last numbers are added and stored as the second number, and so on. You need to check for even and odd length of...

USE C Programming LANGUAGE ONLY PLEASE. We use <stdio.h> if that helps. For the following problems, create the prototype function, calling function “int main()”, and function. So the function prototype, function call, and function header/body should be seen in the answer. The processor directive is not needed. Show a sample call from the int main() function for all problems. If you can for the first one please show proof that it has no errors. 1. Write a function called DisplayColumbiaUniversity...
