Linked lists use dynamic memory allocation i.e. they grow and shrink accordingly. It is collection of nodes.Node has two parts which are as follows −DataLinkTypes of Linked ListsThe types of linked lists in C programming language are as follows −Single / Singly linked listsDouble / Doubly linked listsCircular single linked ...

Intersection operationIf array 1 = { 1,2,3,4,6}  Array 2 = {1,2,5,6,7}Then, intersection of array1 and array 2 isArray1 ^ array 2 = {1,2,3,4,6} ^ {1,2,5,6,7}         = {1,2,6}Set of common elements is called an intersection.The logic for intersection is as follows −k=0; for(i=0;i

In C programming language, we can find the area of circle, area and volume of cylinder with the help of structures.The logic used to find area of circle is as follows −s.areacircle = (float)pi*s.radius*s.radius;The logic used to find area of cylinder is as follows −s.areacylinder = (float)2*pi*s.radius*s.line + 2 * ...

Anagram strings are nothing but, all the characters that occur for the same number of times in another string, which we call as anagrams.A user enters two strings. We need to count how many times each letter ('a' to 'z') appears in them and then, compare their corresponding counts. The ... Read More

A union is a special data type available in C programming language that allows to store different data types in the same memory location. Unions provide an efficient way of using the same memory location for multiple-purpose.Union operationIf array 1 = { 1, 2, 3, 4, 6}    Array 2 ... Read More

In C programming language, nCr is referred as the combination. nCr is the selection of r objects from a set of n objects, where the order of objects does not matter.nPr is referred as the permutation. nPr is arrangement of 'r' objects from a set of 'n' objects, which should ... Read More
