Statements of C++

By Md Shoriful Islam

 Statements

A computer program is a sequence of instructions that tell the computer what to do. A statement is a type of instruction that causes the program to perform some action.

Statements are by far the most common type of instruction in a C++ program. This is because they are the smallest independent unit of computation in the C++ language. In that regard, they act much like sentences do in natural language. When we want to convey an idea to another person, we typically write or speak in sentences (not in random words or syllables). In C++, when we want to have our program do something, we typically write statements.

Most (but not all) statements in C++ end in a semicolon. If you see a line that ends in a semicolon, it’s probably a statement.

In a high-level language such as C++, a single statement may compile into many machine language instructions.

For advanced readers

There are many different kinds of statements in C++:

  1. Declaration statements
  2. Jump statements
  3. Expression statements
  4. Compound statements
  5. Selection statements (conditionals)
  6. Iteration statements (loops)
  7. Try blocks

By the time you’re through with this tutorial series, you’ll understand what all of these are!

 ⭕ Whiteboarding interviews are a common way of assessing the technical and non-technical skills of candidates for software development positions. They involve solving a coding problem or designing a system on a whiteboard, either in person or virtually, while explaining your approach and reasoning to the interviewer.  ⭕ Some of the benefits of whiteboarding interviews are that they can test your problem-solving ability, communication skills, and coding proficiency in a realistic scenario. They can also help you demonstrate your creativity, collaboration, and passion for the role. However, some of the drawbacks of whiteboarding interviews are that they can be stressful, artificial, and biased. They can also favor memorization over understanding and overlook other aspects of your skills and experience.  ⭕ If you want to ace a whiteboarding interview, you should practice beforehand, prepare for the interview setting, set objectives and expectations, create a good candidate ...

Version Control with Git: A Beginner’s Guide

By Md Shoriful Islam
Version Control with Git: A Beginner’s Guide If you are a developer, you probably know how important it is to keep track of your code changes and collaborate with other developers on a project. But how do you do that effectively and efficiently? The answer is version control. Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. It allows you to revert files back to a previous state, compare changes over time, see who last modified something, and more. Version control also enables you to work with other developers on the same code base without stepping on each other’s toes. One of the most popular version control systems in the world is Git. Git is a free and open source distributed version control system that is designed to handle everything from small to very large projects with speed and efficiency. Git has many features that make it superior to other version control systems, such as: Cheap local branchin...

Callback function in JavaScript What is a callback function in JavaScript? A callback function is a function that is passed as an argument to another function and is executed after the first function has completed its task. Callback functions are useful for handling asynchronous events, such as network requests, file operations, or timers. For example, you can use a callback function to display the result of a calculation after the calculation is done. Callback function in JavaScript Here is a simple example of a callback function in JavaScript: // Define a function that takes a callback as an argument function sayHello (callback) { // Do some task console .log ("Hello, world!"); // Invoke the callback function callback (); } // Define another function function sayGoodbye () { // Do some task console .log ("Goodbye, world!"); } // Call the first function and pass the second function as a callback sayHello (sayGoodbye); // The output will be: // Hello, wo...
