In C++ pointer and reference, both are used to access the object indirectly. So it is important to know when to use the pointer and when to use reference. This article explains the difference between pointer and reference (Pointers vs References) in C++. Here, I will discuss some important differences between the reference and pointer […]

This blog post explains the importance and use of the “explicit keyword in C++”. You will learn here when and how to use the explicit keyword in C++ programming with some example codes. But before going in depth-first we need to know that an explicit keyword is a function specifier, like virtual. Note: Function-specifiers can

This blog post explains the importance and use of the “C++ mutable keyword”. You will learn here when and how to use the mutable keyword in C++ programming with some example codes. But before going in depth-first we need to know that mutable is a storage class specifier, like static, thread_local, and extern. What

In this blog post, we will learn about variables, constants, and literals in C++ with the help of examples. C++ Variables: A variable is a storage location that contains some value known or unknown. A symbolic name (identifier) is associated with a variable and usually, we used this name to refer to the stored value.

The C Compilation Process is the sequence of steps that transforms C source code into an executable program. In this process, the source code goes through preprocessing, compilation, assembly, and linking before it can be executed by the computer. This process is necessary because computers cannot directly understand C code. They understand only machine code,

We have already written an article on bit operation and already covered many tricky questions related to bit manipulation. In this blog post, we will only discuss how to write macros for bit manipulation. So let’s see some macros for bit manipulation. If you are new and don’t know how to manipulate bits in C/C++

If you are an embedded software developer, then believe me this article will help you. Before the C99, the C standard only introduced built-in types with no defined size. This ambiguity is intentional in the original C standard to give the compiler vendors more flexibility. But sometimes it creates a problem and reduces portability. According

The assert macro puts diagnostic tests into programs. It is a very good habit to implement a self-test in the program. It solves many critical issues. When the assert is executed, if the expression is false (0), the assert macro writes information about the particular call that failed on the standard error stream in an
