C program to calculate sum of series using predefined function
In C programming, calculating the sum of mathematical series is a common task. This program demonstrates how to calculate the sum of the series: 1 - n²/2! + n⁴/4! - n⁶/6! + n⁸/8! - n¹⁰/10! using the predefined pow() function from the math.h library. Syntax double pow(double base, double exponent); Algorithm The algorithm to calculate the sum of series using predefined function − Step 1: Read the value of n from user Step 2: Initialize factorial = 1, sum = 1, and loop counter Step 3: For each even power from 2 ...
Read MoreC program to count characters, lines and number of words in a file
In C programming, counting characters, words, and lines in a file is a common file processing task. This operation reads through a file character by character and keeps track of different elements based on specific delimiters. Syntax FILE *fopen(const char *filename, const char *mode); int fgetc(FILE *stream); int fclose(FILE *stream); File Operations Overview The three basic operations that we can perform on files are − Open a file − Using fopen() function Process file − Read, write, or modify file contents Save and close file − Using fclose() function Example: ...
Read MoreC program to remove a line from the file
In C, removing a line from a file requires creating a temporary file because files cannot be modified directly in place. The process involves reading the original file line by line, copying all lines except the target line to a temporary file, then replacing the original file. Syntax FILE *fopen(const char *filename, const char *mode); char *fgets(char *str, int n, FILE *stream); int fputs(const char *str, FILE *stream); int remove(const char *filename); int rename(const char *oldname, const char *newname); Algorithm The algorithm to remove a line from a file follows these steps − ...
Read MoreC program to store even, odd and prime numbers into separate files
In C, we can read numbers from a file and categorize them into even, odd, and prime numbers, storing each category in separate files. This involves file I/O operations and number classification algorithms. Syntax FILE *fopen(const char *filename, const char *mode); int fscanf(FILE *stream, const char *format, ...); int fprintf(FILE *stream, const char *format, ...); int fclose(FILE *stream); Note: This program requires creating an input file named "numbers.txt" with integers to process. Since file operations cannot be executed in the online compiler, the code structure is shown for educational purposes. Example ...
Read MoreC program to print name inside heart pattern using for loop.
In C programming, creating a heart pattern with a name in the center is an interesting application of nested for loops. This program generates a heart shape using asterisks (*) and displays a user-entered name in the middle of the pattern. Syntax // Basic heart pattern structure for(i = start; i = end; i--) { // Lower triangular part } Algorithm Follow these steps to create a heart pattern with name − Step 1: Declare variables for loop counters, name array, and pattern size Step 2: Read the ...
Read MoreC program to store the car information using dynamic linked list.
A linked list is a dynamic data structure that grows and shrinks during runtime using dynamic memory allocation. It consists of nodes, where each node contains data and a pointer to the next node. This makes it ideal for storing variable amounts of data like car information. Node Structure Each node in a linked list has two main components − Data − Stores the actual information (car model, color, year) Link − Pointer to the next node in the list Types of Linked Lists The types of linked lists in C programming are ...
Read MoreC program to find the area of circle and cylinder using structures.
In C programming, we can calculate the area of a circle and the surface area and volume of a cylinder using structures to organize related data. A structure helps group related geometric properties like radius, height, and calculated areas in a single unit. Syntax struct shape { float radius; float height; float areacircle; float areacylinder; float volumecylinder; }; Formulas Used Area of circle: π × radius² Surface area of cylinder: 2π × radius ...
Read MoreWhat is an anagram in C language?
An anagram is a word or phrase formed by rearranging the letters of another word or phrase, using all original letters exactly once. In C programming, we check if two strings are anagrams by comparing the frequency of each character in both strings. Two strings are anagrams if they contain the same characters with the same frequency, regardless of their order. For example, "listen" and "silent" are anagrams because both contain one 'l', one 'i', one 's', one 't', one 'e', and one 'n'. Syntax int check_anagram(char str1[], char str2[]); Algorithm The anagram ...
Read MoreC Program find nCr and nPr.
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 be in an order or sequence. Syntax nCr = n! / (r! * (n-r)!) nPr = n! / (n-r)! Permutations and Combinations Formulas The formulas to find the permutation and combination of given numbers in C language are given below − ...
Read MoreC program to perform intersection operation on two arrays
In C programming, an array intersection operation finds all common elements between two arrays. The intersection of two arrays contains only the elements that appear in both arrays, without duplicates. Syntax for(i=0; i
