Code in Perl
Create an array which holds a list of Video Games, consisting of title, the year it was released (guess if you don’t know) , platform (NES, XBOX One, etc) and publisher (in that order). Add at least ten albums to the list. Then, use the split function and a for or foreach loop to display the publisher followed by the title and platform for each list element.
Final review ch6-7
Using arrays create a personal phone directory that contains room for first names and phone numbers for 20 people. Using the "names.txt" retrieve the first name and phone number for each person and store in arrays (parallel).
Prompt the user for a name, search for the name, and if name is found in the array, display the corresponding phone number. If the name is not found, prompt the user to enter a phone number, and add the new name and phone number to the list. Continue to prompt the user for names until the user enters quit or until arrays are full. After the arrays are full (containing 20 names), do not allow the user to add new entries. Print the full list.

Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=Farrow_forward1.

Look for the // TODO comments to find the correct locations. 2. Sorting the array by Age Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library A function that compares two patient elements, based on the value stored in the age field. A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements. Add code to call the qsort function, using the age comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main().

For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no.
