C program to insert a node at any position using double linked list
Linked lists use dynamic memory allocation and are collection of nodes.Nodes have two parts which are data and link.Types of Linked ListsThe types of linked lists in C programming language are as follows −Single / Singly linked lists.Double / Doubly linked lists.Circular single linked list.Circular double linked list.Double linked listThe diagram given below depicts the representation of double linked list.ExampleFollowing is the C program to insert a node at any position using double linked list − Live Demo#include #include struct node { int num; struct node * preptr; struct node * nextptr; }*stnode, *ennode; void DlListcreation(int ...
Read MoreC program to print Excel column titles based on given column number
ProblemA program to print Excel column title that corresponds to a given column number (integer value). User has to enter the integer number based on given number it has to print excel column number.SolutionThe solution to print Excel column title that corresponds to a given column number in C programming language is explained below −Example 1Let us see an example.1 -> A 2 -> B ... 26 -> Z 27 -> AA 28 -> AB ...Example 2The input is as follows −number = 3 number = 27 number = 151The output is as follows −Excel column title: C Excel column ...
Read MoreC program to represent numbers in numerator and denominator in string format
ProblemFind the fraction part from two given integers given by user at run time by using the dynamic memory allocation and represent the numerator and denominator in string format.SolutionThe solution to represent the numerator and denominator in string format is as follows −Example -The input is given below −Numerator1 = 3 Denominator2 = 2 numerator2 = 4 denominator2 = 7The output is as follows −Fractional part1: 1.5 Fractional part2: 0.(571428)ExampleFollowing is the C program to represent the numerator and denominator in string format −#include #include #include #include char* fractionToDecimal(int numerator, int denominator) { char ...
Read MoreWhat is C Operator Precedence and Associativity?
First, let us understand what is operator precedence in C programming language.Operator PrecedenceOperator precedence is used to evaluate the order of operators evaluated in an expression. In C programming, every operator has a priority. When there is more than one operator in the given expression, the operator with higher precedence or priority is evaluated first and the operator with the least priority is evaluated later.Operator AssociativityOperator associativity is used to evaluate the order of operators with equal precedence in an expression. In the C programming language, when an expression contains multiple operators with equal or same precedence, we use associativity ...
Read MoreWhat is program development cycle in C language?
When we want to develop a program by using any programming language, we have to follow a sequence of steps. These steps are called phases in program development.The program development life cycle is a set of steps or phases which are used to develop a program in any programming language.Phases of program developmentProgram development life cycle contains 6 phases, which are as follows −Problem Definition.Problem Analysis.Algorithm Development.Coding & Documentation.Testing & Debugging.Maintenance.These six phases are depicted in the diagram given below −Problem DefinitionHere, we define the problem statement and decide the boundaries of the problem.In this phase, we need to understand ...
Read MoreC program to store inventory system using structures
Structure is a collection of different datatype variables, grouped together under a single name.Features of structureThe features of structure in the C programming language are as follows −It is possible to copy the contents of all the structure elements of different datatypes to another structure variable of its type by using an assignment operator.For handling the complex datatypes, it is better to create structure within another structure, which is called nested structures.It is possible to pass an entire structure, individual elements of structure and an address of structure to a function.It is possible to create structure pointers.ProgramFollowing is the C ...
Read MoreC program to compare if the two matrices are equal or not
The user has to enter the order of two matrices and elements of two matrices. Then, these two matrix are compared.If both matrix elements and size are equal, then it displays that the two matrices are equal.If size of matrix is equal but the elements are not equal, then it displays that the matrix can be compared but is not equal.If the size and elements are not matched, then it displays that the matrices cannot be compared.ProgramFollowing is the C program to compare if the two matrices are equal or not −#include #include main(){ int A[10][10], B[10][10]; ...
Read MoreC program to sort all columns and rows of matrix
ProblemWrite a code to sort all the rows of matrix in an ascending order and all columns in the descending order. The size of matrix and elements of matrix are given by user at runtime.SolutionThe solution to sort all the rows of matrix in an ascending order and all columns in the descending order in the C programming language is explained below −The logic used to sort the rows in an ascending order is as follows −for (i=0;i
Read MoreC program to interchange the diagonal elements in given matrix
ProblemWe need to write a code to interchange the main diagonal elements with the secondary diagonal elements. The size of the matrix is given at runtime.If the size of matrix m and n values are not equal, then it prints that the given matrix is not a square.Only a square matrix can interchange the main diagonal elements and can interchange with the secondary diagonal elements.SolutionThe solution to write a C program to interchange the diagonal elements in given matrix is as follows −The logic to interchange the diagonal elements is explained below −for (i=0;i
Read MoreC program to perform operations on two halves’ in a single array
ProblemWrite a program to accept a one-dimensional array of N elements and split into two halves. Later on, sort the first half in an ascending order and the second half into descending order.SolutionThe solution to perform the two operations on two halves’ in a single array in C programming language is explained below −The logic used to sort the first half in an ascending order is as follows −for (i=0; i
