Create a LookupNames project.
In the main function:Ask the user to enter a number of names, X to quit input.Store the names in an array.Also use a counter variable to count the number of names entered.
Write a function displayNames to display the names.The function must receive the array and the counter as parameters.
Write a function called lookupNames.The function must receive the array and the counter as parameters.Ask the user to enter a letter.Display all the names with the letter that was entered as the first letter of the name.
Call the displayNames and lookupNames functions from the main function.
Tip: declare your functions above the main() function:
void displayNames(char array[][60], int count){ // function code here}
int main(){ // main code here displayNames(names, number); // possible more code here}
Tip2: make sure your function parameter matches the data type you send as an argument to that function.In the above example, names and array should have the same data…

AskForNumbers
Declare an integer array lacally with the size of 200. Create a program that asks the user how many numbers the have. Use your
getChoice() function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200.
Use a for loop and ask the user to enter each value that must be stored in the array.
Use a second loop to display each number, and also determine the average of all values in the array.
After the for loop, display the average of all numbers.
This program will let you enter a list of numbers into an array.
It will then display all of the numbers,
and finally display the average of all numbers.
How many numbers would you like to enter?5

Your program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly answered questions.

Create a file named dedup.js. Write a program that removes duplicates from an array. The program should be able to read an unspecified number of numbers input by the user. The user should enter a negative number when they are done entering scores. The program should remove all duplicates from the array and then iterate over the new array and display it.
