Question

Write the following functioned int search(int a[], int n, int key, int **loc); a is an array to be searched, n is the number of elements in the array, key is the search key, and loc is a pointer to the first location of the search key in array a (if found) or NULL otherwise. The function returns 1 if key is found in a, and returns 0 otherwise. Write a main() and test it. Write a function to convert a string of 32 '1' and '0's in 2's complement form to a 32 bit signed integer: int bits2Integer(char bitString[]); The bit string is stored in the bitString[] argument in "natural" form, i.e., the MSB is on the left side and LSB on the right.

Explanation / Answer

#include<stdio.h>
#include<conio.h>

//main method
void main()
{
   int x[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
   int result = 0;
   int** first_loc = NULL;
   result = search(x, 10, 4, first_loc);
   if(result)
   {
       printf("key found !!");
   }
}

//search function
int search(int a[], int n, int key, int** loc)
{
   int i = 0;
   for(i = 0; i<n; i++)
   {
       if(a[i] == key) //logic to search for key
       {
           loc = &a[i];
           return 1;
       }
   }
  
   return 0;
}
