Q:

What would be the output of the following program?

main()

{

   struct emp

   {

        char *n;

        int age;

   };

   struct emp e1 = { "Dravid", 23};

   struct emp e2 = e1;

   strupr (e2.n);

   printf ("\n%s",e1.n);

}

Answer

DRAVID


When a structure is assigned, passed, or returned, the copying is done monolithically. This means that the copies of any pointer fields will point to the same place as the original. In other words, anything pointed to is not copied. Hence, on changing the name through e2.n it automatically changed e1.n

Q:

Write a c program for binary search.

Answer

#include<stdio.h>
int main(){

    int a[10],i,n,m,c=0,l,u,mid;

    printf("Enter the size of an array: ");
    scanf("%d",&n);

    printf("Enter the elements in ascending order: ");
    for(i=0;i<n;i++){
         scanf("%d",&a[i]);
    }

    printf("Enter the number to be search: ");
    scanf("%d",&m);

    l=0,u=n-1;
    while(l<=u){
         mid=(l+u)/2;
         if(m==a[mid]){
             c=1;
             break;
         }
         else if(m<a[mid]){
             u=mid-1;
         }
         else
             l=mid+1;
    }
    if(c==0)
         printf("The number is not found.");
    else
         printf("The number is found.");

    return 0;
}

Sample output:
Enter the size of an array: 5
Enter the elements in ascending order: 4 7 8 11 21
Enter the number to be search: 11
The number is found.

Q:

Would the following program compile?

main()

{

    int a = 10, *j;

    void *k;

    J = k = &a;

    J++;

    k++;

   printf ("\n%u %u", j, k);

}

Answer

An error would be reported in the statement k++ since arithmetic on void pointers is not permitted unless the void pointer is appropriately typecasted.
