C program to sort an array in an ascending order
Problem Sort the given array in descending or ascending order based on the code that has been written. Solution An array is a group of related data items which share’s a common name. A particular value in an array is identified with the help of its "index number". Declaring array The syntax for declaring an array is as follows − datatype array_name [size]; For example, float marks [50] It declares ‘marks’ to be an array containing 50 float elements. int number[10] It declares the ‘number’ as an array to contain a maximum of 10 integer constants. Each element is identified ...

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 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 −#include #include struct node { int num; struct node * preptr; struct node * nextptr; }*stnode, *ennode; void DlListcreation(int n); ...
Read MoreC program to store even, odd and prime numbers into separate files
A file is a physical storage location on disk and a directory is a logical path which is used to organise the files. A file exists within a directory.The three operations that we can perform on file are as follows −Open a file.Process file (read, write, modify).Save and close file.ProgramFollowing is the C program to store even, odd and prime numbers into separate files −#include #include /* Function declarations */ int even(const int num); int prime(const int num); int main(){ FILE * fptrinput, * fptreven, * fptrodd, * fptrprime; int num, success; ...
Read MoreC program to remove a line from the file
A file is a physical storage location on disk and a directory is a logical path which is used to organise the files. A file exists within a directory.The three operations that we can perform on file are as follows −Open a file.Process file (read, write, modify).Save and close file.AlgorithmAn algorithm is given below to explain the C program to remove a line from the file.Step 1 − Read file path and line number to remove at runtime.Step 2 − Open file in read mode and store in source file.Step 3 − Create and open a temporary file in write ...
Read MoreC program to count characters, lines and number of words in a file
A file is a physical storage location on disk and a directory is a logical path which is used to organise the files. A file exists within a directory.The three operations that we can perform on file are as follows −Open a file.Process file (read, write, modify).Save and close file.ExampleConsider an example given below −Open a file in write mode.Enter statements in the file.The input file is as follows −Hi welcome to my world This is C programming tutorial From tutorials PointThe output is as follows −Number of characters = 72Total words = 13Total lines = 3ProgramFollowing is the C ...
Read MoreC program to find GCD of numbers using recursive function
ProblemFind the greatest common divisor (GCD) for the given two numbers by using the recursive function in C programming language.SolutionThe solution to find the greatest common divisor (GCD) for the given two numbers by using the recursive function is as follows −AlgorithmRefer an algorithm given below to find the greatest common divisor (GCD) for the given two numbers by using the recursive function.Step 1 − Define the recursive function.Step 2 − Read the two integers a and b.Step 3 − Call recursive function.a. if i>j b. then return the function with parameters i, j c. if i==0 d. then return ...
Read MoreC program to compute linear regression
ProblemWrite a program to implement linear regression algorithm.User has to enter total number of values.SolutionThe solution to compute the linear regression in C programming language is as follows −Linear regression finds the relationship between two variables by connecting a linear equation to the observed data. One variable is to be an explanatory variable, and the other is a dependent variable.The logic with regards to linear regression is explained below −for(i=0;i
Read MoreC program to convert decimal fraction to binary fraction
Consider the examples given below to understand how to convert a decimal fraction to binary fraction in C programming language.Example 1 − Conversions of 25 to binary.Step 1 − 25 / 2 Rem : 1 , Quo : 12Step 2 − 12 / 2 Rem : 0 , Quo : 6Step 3 − 6 / 2 Rem : 0 , Quo: 3Step 4 − 3 / 2 Rem : 1 , Quo: 1Step 5 − 1 / 2 Rem : 1 , Quo: 0So equivalent binary number is: 11001Example 2 − Conversions of 0.7 to binary.Step 1 − 0.7 * ...
Read MoreWhat are printf conversion characters and their types?
The use of printf is to print out a string with no blank fields to be filled.For example, printf ("An ordinary string.."); printf ("Testing 1, 2, 3...");The next simplest case that has been used before now is to print out a single integer number.int number = 48; printf ("%d", number);The two can be combined as shown below −int number = 48; printf ("Some number = %d", number);The result of this last example is to print out the following on the screen −Some number = 48Here is a list of the different letters for printf −d − signed denary integeru − ...
