Question

Write code to accomplish each of the following:

1. Define a structure called Dove containing int variable dovNo and char array dovArr with values that may be as long as 25 characters (including the terminating null character).

2. Define dove to be a synonym for the type struct Dove.

3. Use Dove to declare variable a to be of type struct Dove, array b[ 10 ] to be of type struct Dove and variable ptr to be of type pointer to struct Dove.

4. Read a dovNo and a dovArr from the keyboard into the individual members of variable a.

5. Assign the member values of variable a to element 3 of array b.

6. Assign the address of array b to the pointer variable ptr.

7. Print the member values of element 3 of array b using the variable ptr and the structure pointer operator to refer to the members.

Answer 1

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

// 1. structure named 'Dove'

typedef struct Dove {

   

   // Required variables

   int dovNo;

   char dovArr[25];

   

}dove; // 2. synonym for Dove

int main() {

   

   // 3. Declare variable a

   

   struct Dove a;

   

   // Declare array b[10] of type struct Dove

   

   struct Dove b[10];

   

   // Declare variable ptr to be of type pointer to struct Dove

   

   struct Dove *ptr;

   

   // 4. Reading a dovNo and dovArr from keyboard into a

   

   printf("Enter dovNo: ");

   scanf("%d", &a.dovNo);

   printf("Enter dovArr: ");

   scanf("%s", &a.dovArr);

   

   // 5. Assign member of a to element 3 of array b

   // Element 3 will be at index 2

   

   b[2].dovNo = a.dovNo;

   strcpy(b[2].dovArr, a.dovArr);

   

   // 6. Assign address of array b to pointer ptr

   

   ptr = &b;

   

   // 7. Print member values of element 3 of array b using variable ptr

   

   printf("Printing Member values:\n");

   printf("dovNo: %d\n", ptr[2].dovNo);

   printf("dovArr: %s\n", ptr[2].dovArr);

   

   return 0;
