1 Answer

Answer :

Consider an array of five elements as shown below:

A[5]={ 10,20,30,40,50};

image

Search element(SE)=30

Pointer variable is declare as *ptr;

Before starting search process initialize pointer variable with the address of first element in an array.

ptr=&a[0];

Compare *ptr(value at address stored in ptr) with search element in every iteration. After each iteration ptr points to next location in an array.

Iteration1: Check *ptr==SE

If search element is not present in an array, then after comparing all elements stop the search process.
