Write a program using recursion to find the summation of numbers from 1 to n
Learn how to write a recursive program to calculate the summation of numbers from 1 to n in this easy-to-follow guide.
Write a program using recursion to find power of a number
#include <stdio.h>// Function to calculate the power of a number using recursionint power(int x, int y){if (y == 0) // Base case: any number raised to the power of 0 is 1{return 1;}else // Recursive case: multiply x by power of (x, y-1){return (x * power(x, y – 1));}}int main(){int n, m, k;// Ask the […]
Write a program to find GCD of two numbers
The Greatest Common Divisor (GCD) or Highest Common Factor (HCF) of two numbers is the largest number that divides both numbers exactly, without leaving any remainder. The formula used in Euclid’s Algorithm for finding the GCD is based on the idea that: GCD(x, y) = x if y = 0 Otherwise, GCD(x, y) = GCD(y, […]
Write a program to print Fibonacci Series
The Fibonacci series is a sequence where each term is the sum of the two preceding ones, starting from 1 and 1. The sequence looks like this: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, … In this program, we aim to generate and print the Fibonacci series up to a specified […]
C Program to Increment every Element of the Array by one & Print Incremented Array

C Program to Print the Alternate Elements in an Array
#include <stdio.h> // Include the standard input-output libraryint main() // Change void main() to int main(){int array[10]; // Declare an array of size 10int i; // Declare the loop variableprintf(“Enter the elements of the array:n”);// Loop to read 10 integers from user inputfor (i = 0; i < 10; i++) {scanf(“%d”, &array[i]); // Store each […]
C program to accept N numbers and arrange them in an ascending order
#include <stdio.h>// Function to perform bubble sortvoid bubbleSort(int arr[], int n) {for (int i = 0; i < n – 1; i++) {for (int j = 0; j < n – i – 1; j++) {if (arr[j] > arr[j + 1]) {// Swap arr[j] and arr[j + 1]int temp = arr[j];arr[j] = arr[j + 1];arr[j […]
