Assignment purpose: To compile, build, and execute an interactive program using functions from stdio.h (printf and scanf), simple math in C, conditions, a simple loop, and programmer defined functions, with pass by copy input parameters and with input/output parameters. #define _CRT_SECURE_NO_WARNINGS //for Visual studio compiler #pragma warning(disable:6031) //ignore scanf warnings #include //for printf and scanf Instructions: For this assignment you will begin to implement a menu driven program that simulates adds options to a gas station app. The program will welcome the user with a friendly message. The user will be presented with a list of options The user will select from the options below: 'G' to view the gas prices 'P' to purchase gas 'B' to view your account balance 'U' to add money to your account 'Q' to Quit . The user may continue to select the options until entering 'Q' to quit ( you may use tolower or toupper function from ctype.h) 1. For this assignment you will implement the menu and display messages 2. 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 assignments Use the following programmer defined functions. DO NOT modify the Functions
