In this article, you will learn to generate the multiplication table of a number. Examples : Input : 2 Output : 2 * 1 = 2 2 * 2 = 4 2 * 3 = 6 2 * 4 = 8 2 * 5 = 10 2 * 6 = 12 2 * 7 = 14 2 *… Read More »
In this article, you will learn to calculate Sum of First n Natural numbers. The positive numbers 1, 2, 3… are known as natural numbers. The sum of natural numbers up to 10 is: sum = 1 + 2 + 3 + … + 10 Find the sum of numbers for every number from 1 to 4 :… Read More »
This program checks whether the input year is leap year or not. A leap year is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. Leap Year : If a year is divisible by 4, 100 and 400 then it… Read More »
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 »
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 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 »
