Linear Search VS Binary Search
A linear search works by looking at each element in a list
of data until it either finds the target or reaches the end. This results in
O(n) performance on a given list. A binary search comes with the prerequisite
that the data must be sorted. We can leverage this information to decrease the
number of items we need to look at to find our target. We know that if we look
at a random item in the data (let's say the middle item) and that item is
greater than our target, then all items to the right of that item will also be
greater than our target. This means that we only need to look at the left part
of the data. Basically, each time we search for the target and miss, we can
eliminate half of the remaining items. This gives us a nice O(log n) time
complexity.
Just remember that sorting data, even with the most
efficient algorithm, will always be slower than a linear search (the fastest
sorting algorithms are O(n * log n)). So you should never sort data just to
perform a single binary search later on. But if you will be performing many
searches (say at least O(log n) searches), it may be worthwhile to sort the
data so that you can perform binary searches. You might also consider other
data structures such as a hash table in such situations.

Example : Array is best example of linear search and tree

Metric Conversion with structure
Q :Define two structures Metric and British that store distances. The Metric stores values in meters and centimeters and the British stores values in feet and inches. Write a program that reads both structure variables and add values contained in one variable of Metric to the contents of another variable of British. The program should display the result in both: equivalent centimeters and equivalent inches.
Solution :
For solve this question you need to know metric measurement unit.
1 centimeter = 10 millimeters
1 meter = 100 centimeters = 1,000 millimeters

Array pass to function
Array is a collection of similar
data type which occupies continuous location on memory. Array’s name is a
constant pointer which point first element of array. So when an array is passing
to a function. Address of first element pass to function instead of value. If any
change made inside of function body with array, then it affects actual value of
passed array. Following program demonstrate this fact.
#include<stdio.h>
int update(int[]);
void main()
{
int arr[5],i;
for(i=0;i<5;i++)

Sum of series using recursion
Q : Define recursion. Write a complete program to evaluate the given series using recursive function sum( ). Here n is user dependent.
1 + 2 + 3 +…+ n
Solution :
As we C language is known as
building block of functions. This means everything in c language is achieved
through a function. In C language there is not any restriction to call a
function you can call a function from anywhere No matter of scope.
