For this assignment you will implement the menu and display messages2. You will also display the balance when the user enters 'b'3. You will also allow the user to add money to the account when the user enters 'u’The full implementation of a gas purchase will be completed in future assignmentsUse the following programmer defined functions. DO NOT modify the Functions:void Greeting();//welcome the user to the gas station appvoid ViewAndGetSelection(char* selectionPtr);//input: the user's selection (input/output parameter)//display the program options and get the users selection//use an input/output parameter for the selectionvoid ProcessSelection(char selection, double* balancePtr);//input: the user's selection by copy (input parameter)//input: the account balance (input/output parameter)//display a message that the selection has been entered//display the balance when the user enters 'b'//allow the user to add money to the account when the user enters 'u'

Actually, program is an executable software that runs on a computer.
