Overview In this tutorial, we will develop a Java Program to compute Cube of a Number. The program should prompt the user to input the number. The simplest way to compute the cube of a number is: output= n*n*n; Math.pow() However, in Java we can leverage the Math class helper static methods. We cannot instantiate […]
Overview In this post, we will fix the error multiple definition of `main’ in C++ project. The error occurs if the C++ project has multiples main functions defined in the project. Error Sample error log: Documents/CProjects/TestingDocsProject/syntax.cpp:10: multiple definition of `main’ obj\Debug\main.o:/Documents/CProjects/TestingDocsProject/main.cpp:10: first defined here In this example, the source code files syntax.cpp and main.cpp […]
Features Of Linux Operating System In this post, let’s learn some of the features of the Linux operating system. Linux is virtually found and used everywhere. Developers run the code on Linux boxes. Most of the production servers run on Linux machines. Testers run the tests and the DevOps team deploys the application on Linux […]
Overview In this tutorial, we will learn two Linux commands for setting and viewing ACLs (Access Control Lists Commands) in Linux. The commands are getfacl and setfacl commands. These commands are used to set file or directory permissions. setfacl command This command sets the Access Control Lists to files and directories on the Linux box. […]
What is a Computer? Computers are an integral part of our daily lives, revolutionizing how we work, communicate, and entertain ourselves. A computer is an electronic device designed to process and manipulate data. While computers interpret data as sequences of 1s and 0s, they are capable of combining this data to generate meaningful outputs for […]
Overview In this tutorial, we will learn how to draw nested squares using a recursive turtle graphics program. We will use Eclipse IDE to run the python program. Create graphics window and turtle handle. WindowTurtleScreen=turtle.Screen() tDocsTurtle = turtle.Turtle() The recursive function is NestedSquare. This function calls itself. Initially, we will call the function from the […]
