In C programming language, we can use the scanf() and printf() functions to take input and output data respectively. In this article, we will write a C program to print your own name using these two functions in two way. Example 1: In this example, we print the user name using printf() function. // C program to demonstrate printing of // our own name using printf() #include <stdio.h> int main() { // print name printf("Name : Codegyan"); return 0; } Output :  Name :...

Introduction: Linked lists are data structures that store data elements in a linear manner. Each element of a linked list, known as a node, consists of two parts: data and a pointer that points to the next node in the list. A linked list can have one or more loops or cycles, where a node points to a previously visited node in the list. In this article, we will discuss how to find the length of a loop in a linked list using C programming language. Algorithm: To find the length of a loop in a link... Read More

In this tutorial we'll learn how to check whether a given integer is positive or negative. We have the the number that we need to check that integer is positive or negative number using c program. Problem Description The program takes the given integer and checks whether the integer is positive or negative. Problem Solution 1. Take the integer which you want to check as input. 2. Check if it is greater or lesser than zero and print the output accordingly. 3. Exit. Program/So... Read More

Given an array of integers, our task is to write a program that efficiently finds the second largest element present in the array. Example: Input: arr[] = {12, 35, 1, 10, 34, 1} Output: The second largest element is 34. Explanation: The largest element of the array is 35 and the second largest element is 34 Input: arr[] = {10, 5, 10} Output: The second largest element is 5. Explanation: The largest element of the array is 10 and the second largest element is 5 Input: arr[] =... Read More

Given an unsorted array and an element x, search x in given array. Write recursive C code for this. If element is not present, return -1. Approach : The idea is to compare x with the last element in arr[]. If an element is found at the last position, return it. Else recur elmntSrch() for remaining array and element x. Program : /* * Approach : The idea is to compare x with the last element in arr[]. * If an element is found at the last position, return it. * Else recur el... Read More

Program : C Program to Merge Two arrays in C Programming #include<stdio.h> int main() { int arr1[30], arr2[30], res[60]; int i, j, k, n1, n2; printf("\nEnter no of elements in 1st array :"); scanf("%d", &n1); for (i = 0; i < n1; i++) { scanf("%d", &arr1[i]); } printf("\nEnter no of elements in 2nd array :"); scanf("%d", &n2); for (i = 0; i < n2; i++) { scanf("%d", &arr2[i]); } i = 0; j = 0; k = 0; // Merging starts while (i < n1 &...
