In C++ please!!

Write a program that will fill an integer array with random values. Then, the user will be given the choice to see: 1) the average, 2) the value in a cell indicated by the user, or 3) the odd numbers in the array. The options should be presented as a menu, with a fourth choice that would be to end the program, without performing any of the operations.

Prototypes:

void intro(); // a description of what the program will do

void menu(); // displays the menu

void fillArray(int[]); // fills the array with random values in the range 0 - 199

int getChoice(); // prompts the user to enter a menu choico & returns that choice

void computeAverage (int[]); // computes & displays the average of values in the array

void displayOne(int, int[ ]); // the displays the value in the cell indicated by the user

void showOdds(int[]): // displays the odd values in the array (referring to the actual values, not the cell numbers)
