C program to convert roman numbers to decimal numbers
Roman numerals are a numeral system that originated in ancient Rome and remained the usual way of writing numbers throughout Europe. In C programming, converting roman numbers to decimal requires understanding the basic roman symbols and their subtraction rule. Roman Numeral System The basic roman numerals and their decimal values are − Roman Decimal Roman Decimal I 1 L 50 V 5 C ...
Read MoreC program to compute geometric progression
In C programming, a geometric progression (GP) is a sequence where each term after the first is found by multiplying the previous term by a common ratio. The sum of a geometric progression follows the formula: 1 + x + x² + x³ + ... + xⁿ. Syntax sum = 1 + x + x² + x³ + ... + xⁿ Algorithm The algorithm to compute geometric progression is as follows − Read values for x (common ratio) and n (number of terms) Initialize sum to 0 Use a loop to calculate ...
Read MoreC Program to delete n characters in a given string
In C programming, deleting n characters from a specific position in a string involves shifting the remaining characters to fill the gap. This operation modifies the original string by removing a substring starting from a given position. Syntax void deleteString(char str[], int position, int n); Algorithm The algorithm to delete n characters from a given position in a string is as follows − Step 1 − Read the input string Step 2 − Read the starting position for deletion Step 3 − Read the number of characters to delete Step 4 − ...
Read MoreC program to find GCD of numbers using recursive function
The greatest common divisor (GCD) of two numbers is the largest positive integer that divides both numbers evenly. In C programming, we can find the GCD using the Euclidean algorithm implemented with a recursive function. Syntax unsigned int GCD(unsigned i, unsigned j); Algorithm The recursive GCD algorithm follows these steps − Step 1 − Define the recursive function. Step 2 − Read the two integers a and b. Step 3 − Call recursive function with the following logic: a. if j > i then return GCD(j, i) b. if ...
Read MoreC 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 ...
