Reverse a Number in C Language :- This program reverse the number entered by the user and then prints the reversed number on the screen. For example if user enter 123 as input then 321 is printed as output. In our program we use modulus(%) operator to obtain the digits of a number. To invert number look at it...
The length and breadth of a rectangle and radius of circle are input through the keyboard.Write a program to calculate the area and perimeter of the rectangle, and the area & circumference of the circle. Covered Area Problem is a classic algorithm problem used for academic teaching purposes. The basic idea is to give several pairs of Cartesian coordinates as...

My boot loader is GRUB (see LILO boot loader below) Following is the procedure to reset root password if you are using GRUB as a boot loader: Select the kernel Press the e key to edit the entry Select second line...
Algorithms is used for solve the problem step by step. It is the part of Software Designing. An Algorithm defines as the step by step method that can be carried out for solving programming problems. An Algorithm tells Computer that how to solve the problem Systematically to get desired output. We follow following steps to design an algorithm.Step 1...
Write a program using conditional operators to determine whether a year entered through the keyboard is a leap year or not. Definition of leap year: Rule 1: A year is called leap year if it is divisible by 400. For example: 1600, 2000 etc leap year while 1500, 1700 are not leap year. Rule 2: If year is not divisible by 400...
Introducing -- Code ! A new and open zone for budding programmers like me and for amateur developers. I believe that writing codes is not a rocket science, it's fun and interesting. Most people don't find coding fun because they don't see the beauty or they find it difficult. But it's not at all difficult and it's very much fun, you will soon find...
Facebook has designed a new programming language called Hack but it has nothing to do with hacking. It lets programmers build complex websites and other software quickly and without many flaws. "We can say with complete assurance that this has been as battle-tested as it can possibly be," - according to Bryan O'Sullivan, the Facebook engineer behind the language, said...
Write a Program in C to check whether a given number is palindrome or not. The simplest method is to reverse the digits of the original number and check to see if the reversed number is equal to the original. This is not an efficient way of doing it but, for ints or long ints, it works well enough What is...
Indian IT industry has seen many ups and down. After technologically advanced nations denied supply of supercomputer to India in mid-1980s, Center for Development of Advanced Computing (C-DAC) was set up in 1987. Indian Super computer, PARAM series has shown some strength but does it stands along with world's leading Supercomputers? A big NO. India's top supercomputer at present...
