Question

You will modify Project 3 to include a student struct. The struct should include 3 data members a char array (for the name), a char array (for the housing response), and an int (for units). The four functions will all need to be modified to take a pointer to a student struct. Make the necessary modifications to the code in the function body.

You will also provide a menu interface for the user. The menu will initially allow the user to enter a student or quit the application. Once the user has entered a student, the option to print all students should be added to the menu. When the user quits the application, print the student name and amount due for each student entered. Then print the total and average tuition cost for all students entered during that session. If no students were entered, print something stating no students were entered. Allow the user to enter up to 10 students in one session.

Sample Run:

**************************************************
Student Data Entry Application
**************************************************
1: Enter a student
q: Quit the application
>>> 1

Enter student name: Student One
Enter yes if student lives on campus, no otherwise: yes
Enter current unit count: 15

1: Enter a student
2: Print student list
q: Quit the application
>>> 2

Student name: Student One
Housing response: yes
Units Enrolled: 15

1: Enter a student
2: Print student list
q: Quit the application
>>> 1

Enter student name: Student Two
Enter yes if student lives on campus, no otherwise: no
Enter current unit count: 7

1: Enter a student
2: Print student list
q: Quit the application
>>> 1

Enter student name: Student Three Jr.
Enter yes if student lives on campus, no otherwise: yes
Enter current unit count: 11

1: Enter a student
2: Print student list
q: Quit the application
>>> q

Student name: Student One
Amount due: $2470

Student name: Student Two
Amount due: $700

Student name: Student Three Jr.
Amount due: $2100

The total cost is $5270.00.
The average cost for these 3 students is $1756.67.

Please find the code below:::

#include <stdio.h>
#include <stdlib.h>

struct student{
   char name[100];
   char housing[100];
   int count;
};
void printMenu(){
   printf("1: Enter a student\n");
   printf("2: Print student list\n");
   printf("q: Quit the application\n");
}

int main(int argc,char * argv[])
{
   printf("*************************************************\n");
   printf("Student Data Entry Application\n");
   printf("*************************************************\n");
   struct student students[10];
   int index = 0;
   char choice;
   while(1){
       printMenu();
       printf("Enter your choice : ");
       scanf("%c",&choice);
       while(choice=='\n'){
       scanf("%c",&choice);  
       }
       if (choice=='1'){
           printf("Enter student name: ");
           scanf("%s",students[index].name);

           printf("Enter yes if student lives on campus, no otherwise: ");
           scanf("%s",students[index].housing);

           printf("Enter current unit count: ");
           scanf("%d",&students[index].count);

           index++;
           if(index==10){
               break;
           }
       }else if(choice=='2'){
           int i;
           for(i=0;i<index;i++){
               printf("Student Name : %s\n",students[i].name);
               printf("Housing response : %s\n",students[i].housing);
               printf("Units Enrolled : %d\n",students[i].count);
               printf("\n\n");
           }
       }else{
           break;
       }
   }
  
  
   float amountDue = 0;
           float dueAmount;
           int i;
           for(i=0;i<index;i++){
               printf("Student Name : %s\n",students[i].name);
               printf("Amount Due : ");
               scanf("%f",&dueAmount);
               amountDue+=dueAmount;
           }

           printf("The Total cost is : %.3f\n",amountDue);
           printf("The average cost for these %d students is $%.3f.",index,amountDue/index);
       return 0;
  
}

output:
