Question

(Write a program, and show the output too) C programming

I have a hard time to get these five questions done. I am thankful if someone can help me with that.

I started with something but i couldn't get it done.

That's what I've done.

#include <stdio.h>
typedef struct _profile {
   char name[32];
   int age;
} Profile;

Profile prof[3] = {"myName", 19}, {"bob", 12}
arr[1] = prof;

for (int i = 0; i < 3; i++)
{
   printf('%s', arr[i].name);
}

Consider this

struct _profile {

char name [32] ;

int age;

}

That's the assignment.

Use the above structure

put all the below questions in one main file, compile and run, show the output.

11. Define a array of structures with three cells using the above structure. Name the array Profile ;

12. Assign the cell at index 0 : name = "Cindy", age = 28;

Assign the cell at index 1 : name = "Sean", age = 38;

Assign the cell at index 2 : name = "John", age = 23;

13. print the values of all structures using a for loop.

14. Define a array of structures with three cells using the above structure. Name the array ProfileBackup [ 3 ] ;

Copy all three cells from Profile array to ProfileBackup using a for loop.

15. Search and print the index of the cell where you could find "John".

Answer 1

11. Define a array of structures with three cells using the above structure. Name the array Profile ;

// array of structures 3 cells
   Profile prof[3];

12. Assign the cell at index 0 : name = "Cindy", age = 28;

Assign the cell at index 1 : name = "Sean", age = 38;

Assign the cell at index 2 : name = "John", age = 23;

// assign the value to it
   strcpy(prof[0].name , "Cindy");
   prof[0].age = 28;
   strcpy(prof[1].name ,"Sean");
   prof[1].age = 38;
   strcpy(prof[2].name , "John");
   prof[2].age = 23;

13. print the values of all structures using a for loop.

// print the prof data
   for (i = 0; i < 3; i++)
   {
   printf("Name is : %s, Age is : %d\n", prof[i].name,prof[i].age);
   }

14. Define a array of structures with three cells using the above structure. Name the array ProfileBackup [ 3 ] ;

Copy all three cells from Profile array to ProfileBackup using a for loop.

   // copy backup data
   Profile ProfileBackup[3];
   for (i = 0; i < 3; i++)
       ProfileBackup[i] = prof[i];

15. Search and print the index of the cell where you could find "John".

// finding the index of John
   for (i = 0; i < 3; i++)
   {
       if(strcmp(ProfileBackup[i].name,"John") == 0)
           printf("The index of John is : %d\n",i);
   }

Complete Code:

#include <stdio.h>
#include <string.h>
typedef struct _profile {
char name[32];
int age;
} Profile;
int main()
{
   int i;
   // array of structures 3 cells
   Profile prof[3];
  
   // assign the value to it
   strcpy(prof[0].name , "Cindy");
   prof[0].age = 28;
   strcpy(prof[1].name ,"Sean");
   prof[1].age = 38;
   strcpy(prof[2].name , "John");
   prof[2].age = 23;
     
     
   // print the prof data
   for (i = 0; i < 3; i++)
   {
   printf("Name is : %s, Age is : %d\n", prof[i].name,prof[i].age);
   }
  
   // copy backup data
   Profile ProfileBackup[3];
   for (i = 0; i < 3; i++)
       ProfileBackup[i] = prof[i];
      
      
   // finding the index of John
   for (i = 0; i < 3; i++)
   {
       if(strcmp(ProfileBackup[i].name,"John") == 0)
           printf("The index of John is : %d\n",i);
   }
   return 0;
}

Output:

Name is Cindy. Age is 28 Name is Sea Age is 38 Name is John, Age is 23 The index of John is 2
