You might have come around two types of people in your life till now. One always talks about equality and the other who thinks that not everyone is equal in whatever manner. Since C++ is also not so much different from our real-life scenarios, the two operators like the thinking exist. These come under the…
At one time, all of us were tired of maths, but it has some fundamental concepts still in use, and everyone might know about it: Constants. Like in our life, we have some constants, i.e., whose place no one can take or which can not be changed, and in mathematical terms, its value can not…
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.…
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…
