C program for binary search: Binary search works only in sorted array. Prerequisite of binary search is that array should be sorted. If you want to implement binary search in unsorted array then you should sort array using any sorting algorithm like merge sort, quick sort etc and then implement binary search.

Bubble sort in c: Bubble sort is the simplest algorithm for sorting elements of array. We can sort elements in ascending and descending order using bubble sort algorithm.

Simple C program to find and print common characters in two strings. This program will find common character and will print them. This program will print common characters with frequency of character that are present in both strings.

This program will find the character with highest occurrence in string. If there are two or more character with highest and same frequency in string then program will print alphabetically first character in string. For example if string is "programmingside". Here 'g', 'r', 'm', 'i' occurring  two times so program will print 'g'.

Simple C program to remove duplicates from array.

Given a sorted array and remove duplicates from array. Simple C program to remove duplicates from array.

Prerequisite for binary searching is the array should be sorted Otherwise binary searching will not work fine. If we apply binary searching in unsorted array then it can give correct answer by mistake.

Simple C program to find pair in array. Simple method is run two for loop and find pair.

Simple C program to count frequency of each character in a string. If string a "programmingside" then frequency of characters:

Given two strings, count total number of common characters. For example if two strings are "coder" and "side" then common characters are 2 ( 'd' and 'e' ). If strings are "Programming" and "Side" then common character is 'i'. If strings are "aabbcc" and "aabcc" then common characters are 5 ( 2'a', 1'b', 2'c' ).

Simple C Program to count total number of node in a linked list using recursion. Count total number of nodes using iterative method.

Simple C Program to count total number of elements in a linked list.

In this post, we are giving interview questions that are asked in interview. These questions might help you in the interview. Here these programs are asked in interview to our friends and colleagues. There are also so many questions that are asked in interview.

Convert number from octal to binary. Octal number is a base 8 number and octal number contains 0,1,2,3,4,5,6,7 digits and binary number is a base 2 number and it contains 0 and 1.

Simple C program to rotate matrix by 90 degrees.

Given a matrix. Rotate it by 90 degrees.

A array is given and sort it in the wave form. Wave form of a array: If array is {1,4,2,7,8,4,9,3} then sort it like {4,1,7,2,8,4,9,3}. Like arr[0]>=arr[1]<=arr[2]>=arr[3]<=arr[4]....

You are given a matrix arr[m][n] then print it in the wave form as given in the image.

Simple C program for decimal to octal conversion

Decimal number is a base 10 number and hexadecimal number is base 16 number. In decimal number number there are 0 to 9 digits and in hexadecimal number 0 to 9 digits plus A, B, C, D, E ,F characters. Number 1324 is a decimal number and number 1A2 is hexadecimal number.

Simple C++ program to calculate sum of diagonal elements of a matrix.

Transpose of a matrix is a matrix whose columns are rows of original matrix and rows are columns of original matrix.

In mathematics, to multiply two matrix what we do. First we check the number of column in first matrix is equal to number of rows in second matrix. If they are not equal then we can't multiply them.

Simple C++ program to subtract one matrix from another matrix and store data into third matrix and then print third matrix.

Simple C++ Program to add two matrix into third matrix. To add two matrix , we add corresponding position elements of both matrix.

Simple C++ program to print matrix. To print matrix, we use two for loop. First for loop is for rows in matrix and second for loop is for columns in matrix.

Simple C++ program to calculate sum of array elements. To calculate sum of array elements, first we declare a variable sum and initialize it to 0 and then add array elements one by one into sum.

Here is a simple C++ program to count total number of digits in a number. To count digits, we use log. And for this purpose we use cmath library.
