# Write a program in c language to implement binary search using pointers

Initialize a pointer to first and last element of array. However, the binary search, look for an element by dividing the array into two half, then compare the key element with a calculated mid value. Input size and elements in array.

Then the user is given two choice of search algorithms — linear search and binary search. The user first enters the array size and array elements. This part is implemented using C switch-case statements.

## Binary search program in c without using function

However, the binary search, look for an element by dividing the array into two half, then compare the key element with a calculated mid value. Example Input Input array elements: 10 20 30 40 50 60 70 80 90 Input element to search: 25 Output 25 does not exists in array. Required knowledge In my previous posts related to array, I have explained how easily we can search an element in array without using pointer. Input size and elements in array. But if he wants to use the binary search, the user must enter sorted values. Logic to search an element in array using pointers in C program. Recommended posts. The linear search is probably the oldest search algorithm, it goes through each and every element of the unsorted array and look for the key, you are searching for. Initialize a pointer to first and last element of array. Then the user is given two choice of search algorithms — linear search and binary search. The user first enters the array size and array elements.

The linear search is probably the oldest search algorithm, it goes through each and every element of the unsorted array and look for the key, you are searching for.

But if he wants to use the binary search, the user must enter sorted values. Recommended posts.

### C program to search an element in an array using pointers

Store them in some variable say size and array. If the key is greater than the mid value, go to the right half of array, and perform the same steps again. Then the user is given two choice of search algorithms — linear search and binary search. Example Input Input array elements: 10 20 30 40 50 60 70 80 90 Input element to search: 25 Output 25 does not exists in array. How to search an element in array using pointers in C programming. Here in this post we will see how to search an element in array using pointer. Recommended posts. The binary search is faster, but it requires that the array is already sorted in ascending order or descending order. But if he wants to use the binary search, the user must enter sorted values. If key is less than or equal to mid value, go left half and keep doing the same thing all over again. The user first enters the array size and array elements. Initialize a pointer to first and last element of array.

Store them in some variable say size and array. You are not allowed to see ads Problem Definition The program implements two search algorithm — linear search and binary search. Below is another implementation of search function without index variable.

Required knowledge In my previous posts related to array, I have explained how easily we can search an element in array without using pointer.

Output — Linear Search and Binary Search.

Below is another implementation of search function without index variable. You are not allowed to see ads Problem Definition The program implements two search algorithm — linear search and binary search. Output — Linear Search and Binary Search. Here in this post we will see how to search an element in array using pointer. Logic to search an element in array using pointers Below is the step by step descriptive logic to search an element in array using pointer. But if he wants to use the binary search, the user must enter sorted values. However, the binary search, look for an element by dividing the array into two half, then compare the key element with a calculated mid value. The user first enters the array size and array elements. Example Input Input array elements: 10 20 30 40 50 60 70 80 90 Input element to search: 25 Output 25 does not exists in array.
