Write a Elevator Simulator program in C! Without using goto statements! Simulate an Elevator-Controller Program, the Elevator should be able to travel between five floors namely Ground, 1st, 2nd, 3rd, 4th and 5th floors. The elevator can travel going up (unless they are at the 5th floor) or going down (unless they are at the ground floor). The elevator can only contain one passenger (which is the current user of the program). Initially the elevator begins and loads at the Ground Floor. If the user wants to travel to the 5th floor, the elevator shall go up to the said floor. It is the option of the user if they want to alight the elevator or not on the 5th floor or any floor on the way. Realistic rules should apply: If the user alights at the 4th floor, when they ride the elevator again, it should begin traveling from the 4th floor and from there choose to go up or down. Your program should have some validation: meaning, only the valid characters should be received by the program (G, 1, 2, 3, 4, 5). If the user keys-in “A” or “-1”, the program should be able to handle such input and not crash and ask for a correct valid input. The elevator can also travel from B1 to B3 (Basement 1 to 3). The elevator can also allow new passengers to ride the elevator during the trip of the first user. The number of passengers per trip can vary.  Please do the whole program or dont do it i have already got plenty of half responses and wasted 10 questions
