Question

Given an amount of RAM (in megabytes) that is provided by the user, write a program that utilizes the stack or queue concept where the program allocates space used by the applications listed above. Data Structure: Use a linked list structure. Bonus: Create an array data structure that runs parallel to the linked list structure. Actions: The program will continue to ask the user to select an application to run until they decide to quit the program. When the user decides to quit, the program will print all the current running items on the stack and the amount of RAM (in megabytes) currently available on the computer. If the computer doesn't have enough memory to run an application, applications arc removed from the stack or queue until enough memory is available to run the application. So. there will never be an instance where an application cannot be run.
