Global variables are described at the top of a program, outside of all functions. The value of a global variable remains constant throughout the execution of the program. Every function that is declared in the program, can access the global variable. #include<iostream> using namespace std; //global variable int a = 5; void display() { cout<<a<<endl; …
In this article, we look into the delay() function in C++. There can be many cases where we need to create a delay in our programs before exiting out of execution. We can use a delay for this purpose in our code which is used to delay the program’s exit time. We can call the delay …
Most new C++ programming students are taught to add “using namespace std” in the global scope after introducing the headers needed for their programs to compile successfully. As a result, students grow accustomed to engaging in this practice without realizing how bad it is. Including ‘using namespace std’ in the global scope is bad practice. …

In this section we will be studying the concepts of variables in C++ programming language. We hope you guys must have heard about variables in C or somewhere else. Though it is not a very complex topic to discuss in detail but let’s see what we have to say for this. C++ Variables We can …
Here you will learn about C++ tokens, keywords, constants, identifiers, strings, operators and special symbols. What are Tokens? In simple words, we can say that tokens are the smallest component pertaining to any program that make sense to the compiler, i.e. compiler can very easily understand that. We can classify the tokens into six different …

We have completed the basic introduction to C++ and the language features. Hoping that you have set the environment necessary to run the C++ programs in your machine. Let us jump to write first C++ program to print hello world. Before that we need to know some basics of the language. The ISO C++ standard …
Computer can’t directly understand the program that we write in C++ language. Compiler converts the program into machine language that is understand by the computer. As we already know C++ is a compiled language. This means that every source file needs to be converted into an intermediate code called the object code with the help …
To say exactly, creating a computer program is like trying to swim an ocean. You will eventually drown if you jump into it without proper knowledge. So, the question here is, in which language you should start training to get strong grip in software field. The answer is ambiguous. You can start with any language …
