In this article, you will learn to find the quotient and remainder when an integer is divided by another integer. Examples : Input: A = 2, B = 7 Output: Quotient = 3, Remainder = 1 Input: A = 27, B = 5 Output: Quotient = 5, Remainder = 2 We can compute quotient and remainder using division… Read More »
In this article, you will learn to swap two numbers in C programming. Examples : Input : x = 10, y = 20; Output : x = 20, y = 10 Input : x = 50, y = 100 Output : x = 100, y = 100 Algorithm : Assign x to a temp variable, i.e., temp =… Read More »
C Program for Sum of digits of a given number. Examples : Input : 123 Output : 6 Input : 1995 Output : 24 Algorithm : To get sum of each digits by c program, use the following algorithm: Get number by user Get the modulus/remainder of the number Sum the remainder of the number Divide the number… Read More »
In this article, you will learn to calculate the factorial of a number. Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example factorial of 6 is 5*4*3*2*1 which is 120. The factorial of a positive number n is given by: factorial of n (n!) = 1 * 2 *… Read More »
In this article, you will learn to print the Fibonacci sequence of first n term. Fibonacci Series generates subsequent number by adding two previous numbers. The first two terms of the Fibonacci sequence are 0 followed by 1. The Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21 … In mathematical terms, the sequence Fn of… Read More »
In this example, you will learn to reverse the given number using these two methods. Examples : Input : 123 Output : 321 Input : 1995 Output : 5991 Approach used : We can reverse a number in c using loop and arithmetic operators. Take input number Find its quotient and remainder. Multiply the separate variable with 10… Read More »
C Program to check whether the given integer is positive or negative. Examples : Input: 50 Output: Number is Positive. Input: -25 Output: Number is Negative. Input: 0 Output: Number is Positive nor Negative, i.e. 0 Approach used : A number is said negative if it is less than 0 i.e. num < 0 and said positive if… Read More »
In this article, you will learn to print “Hello, World!” on the screen in C programming. Most students of programming languages, start from the famous ‘Hello World’ code. This program prints ‘Hello World’ when executed. In the first program we are displaying the message using printf function and in the second program we are calling a user defined… Read More »
Given an integer n, find value of its square root. Examples : Input: n = 16 Output: 4 Input: n = 8 Output: 2 Note – floor value of 2.8 is 2. There can be many ways to solve this problem. Method-1: Simple Approach, in O(√ n) time complexity Output : 2 Note – If n is not… Read More »
