Question

Write code for the following program in C. As per proper coding practice, plan out your program with psuedocode and include this before the main function.

I visited Fields Museum in Chicago few months ago to look at Mummy’s. You have been asked to write a program that can be used to control the number of people who can be in the exhibition room at the same time. Groups of people can always leave the room (if they are inside), but a group cannot enter the room if they would make the number of people in the room exceed the maximum of 149. There are 5 security guards in the room at all times. Write a program that reads the sizes of the groups that arrive or depart (user can enter those). Use negative numbers for departures. After each input, display the current number of visitors. As soon as the room holds the maximum allowable number of visitors, report that the room is full and stop accepting new groups (i.e., if a new group arrives, display a message stating that the room is full and no entry is allowed until we have room. You may admit some members from the group if possible depending on the available room). Exit the program if no one from 2 consecutive groups can’t enter.

Answer 1

Pseudo Code:

1. Initialize the variable: max_people = 249 and gaurds = 5 and current number of people in room to 0
2. Create variables to check the vacant space,to take the input and a counter to check the consecutive number of time group was not able to enter.
3. Add the number of guards to the current number of people
4. start an infinite while loop
5. Take the size of the group from user
6. display the current number of people in room
7. update the vacant_space
8. if the size entered is negative then remove that many people from room and make sure number of people in room is not negative and set the counter to 0;
9. else
10. if vacant space is 0 then return room full message and increment counter
11. if size<=vacantspace then add the group in room and set counter to 0
12. if vacant space is less than size then update the people in room by adding the number left in vacant space. and set counter to 0.
13. check for the counter value if it is 2 then terminate else continue

******** CODE *********

#include<stdio.h>

#define MAX 149

int counter = 0;

int people_in_room = 0;

int main(){

    int number_of_gaurd = 5;

    int size;

    int vacant_space;

    people_in_room+=number_of_gaurd;

    while(1){

        printf("Enter the size of group: ");

        scanf("%d",&size);

        printf("Current number of visitiors %d\n",people_in_room);

        vacant_space = MAX - people_in_room;

        if(size<0){

            people_in_room+=size;

            counter = 0;

            if(people_in_room<0)

                people_in_room=0;

        }

        else

        {

            if(vacant_space==0){

                printf("room is full and no entry is allowed until we have room\n");

                counter++;

            }

            else if(size<=vacant_space){

                people_in_room += size;

                counter = 0;

            }

            else{

                people_in_room +=vacant_space;

                counter = 0;

            }

            

        }

        if(counter>2){

                printf("Terminating program\n");

                return 0;

        }

    }

}
