In C++, the main() function is a very important function. It is responsible for starting a program, controlling the flow through the program, and providing a place in the program for error reporting.
What is Main() Function?
The main() function is the central entry point to a C++ program. It has two main jobs. First,…
Identifiers in C++ are a way of naming things. They are names for variables, functions, classes, and more. The number of unique identifiers is essential because it limits the scope of a variable, for example. Identifiers follow specific rules and provide some protection from mistakes.
In the previous blog, "keywords in c++," we studied the…
Keywords in C++ are the collection of reserved words and predefined identifiers. These are written in lower cases and have a special meaning defined by the compiler. There are 95 keywords in the C++ programming language, of which around 30 are unavailable in the C language. These are always used for a particular purpose in a program,…
A namespace is a group of related terms, classes, or attributes that exist within your project. Usually, namespaces have some sort of contextual relevance that influences their structure.
When we start writing any program, we add a pre-processor directive, but it does not end here. Our basics for writing a code include much more than…
The compilation is an important phase of the software development cycle. The compilation is not a short task to perform and has many stages. The first stage is called preprocessing. The Preprocessor of the C++ programming language is a computer program and code used to perform different types of tasks before compiling the source code.…
C++ is a very convenient and easy language to learn as it's a language that provides access to even minor and critical details. Wrapped up within these extraordinary features, we have a unique operator known as the "sizeof" function. The sizeof c++ is one of the fundamental operators used for reference while programming.
The Sizeof…
As we know, data types are essential to declare a variable in our program, but isn't the efficiency of our program important? Don't you think so? The answer is "Yes, it is"; hence, in C++, an introduction to data type modifiers is crucial. Let's understand the Modifiers in C++ to get the answer "what are…
People are known by their families’ names when they are born. Similarly, every piece of information is of a family. And this family of data together is what we call data types. Now, if you think it’s the end; well, it’s not; there’s a lot more to it, so let’s get started.
So now you…
Comments are used to add information or explain what the piece of code does without changing the code's functionality. They're also helpful for programmers who don't speak English well. Comments ignore the additional information as we use comments in our source code that do not get printed, executed, or compiled by the compiler. Thus, they…
In the journey of the C++ programming, we would see tons of errors and warnings, which will restrict our program from successful execution and will lead to headache(s) as well; It just gives us an idea of whether we should let our system die by throwing our screen on the wall or use our brand…
