Question

Write and test a function search( ) that searches for an integer s in an array of n elements. If s is found to match an element in the array, the function returns the address of that element; otherwise it returns NULL. The function must use the travelling pointer (version-2) notation to traverse the array. The function has the following prototype. int* search ( int *p , int s, int n) 2. Write and test a function search( that searches for an integer s in an array of n elements. If s is found to match an element in the array, the function returns the address of that element; otherwise it returns NULL. The function must use the travelling pointer (version-2) notation to traverse the array. The function has the following prototype. int search int *p, int s, int n)

Explanation / Answer

#include<stdio.h>

int * search(int *ptr,int s,int n)
{
   if(n<0)
   return NULL;
   if(*(ptr+n)==s)
   return (ptr+n);
   else return search( ptr,s,n-1);
}
int main()
{
   int array[]={8,9,4,2,6,7,5}; // Array of an element
   int s=2; // search element
   int *ptr;
   int n=sizeof(array)/sizeof(array[0]);
   ptr=search(array,s,7);
     
   printf("%d",ptr);// print the address of an element;
printf(" %d",*ptr);// print an element
}
