Question

Write a function called FirstElements for adding 100 random integers between 100 to 1000 to myList. using C program

Project: List management Goa l: creating, updating and displaying a list using a menu. Instruction: Create an array called myList. Write a function called FirstElements for adding 100 random integers between 100 to 1000 to myList Initialize the first 100 elements of myList by calling the FirstElements function. Create a menu to display the following options and a number corresponding to each option which is used for selecting the desired option: Create a menu to dihefolwing ootions and a number 1- adding any amount of numbers to myList o 2-removing all occurrences of a selected number from myList o 3- finding and displaying the maximum, minimum and range (maximum-minimum) in myList o 4- finding the number of occurrences of a number in myList o5- doubling (multiplying by 2) all numbers in myList o 6- display all members of myList. o 7- quit for each menu item create a function. when the item number is typed, the function should be executed, the required inputs should be requested, and the proper output should be produced. the outputs can be formatted in a proper fashion of your choice after executing any function in the menu, the user should be given the choice to select another menu or quit (Y for the new request and Q for quit). · if the user has a new request, the menu should appear again and the process repeated.
