The allocation of dynamic memory is very simple, we need to call a library function (malloc, calloc, etc.) to allocate the memory at runtime (from the heap), after using the allocated memory it again called a different function (free, realloc) to release the allocated memory. The allocation of memory at the runtime is great features […]

In this article, I shall not discuss the all the storage duration, only discuss the dynamic memory allocation and the library function that is used to allocate memory at runtime. There are also some advantage and disadvantage of dynamic memory allocation, so I shall also try to focus on this points. According to C standard,

The const volatile are fascinating keywords that make many people confuse. The volatile keyword is a type qualifier that prevents the objects from the compiler optimization. According to C standard, an object that has volatile-qualified type may be modified in ways unknown to the implementation or have other unknown side effects. You can also say

In this tutorial, you will learn about the dangling pointer, void pointer, NULL, and wild pointer in C. I have already written a brief article on these topics. The main aim of this blog post to give you a quick introduction to these important concepts. Also, I will describe different states of the pointer with

Generally, I saw many people asked the question that what is the difference between memcpy and memmove (memmove vs memcpy)?. So to solve the question I am writing an article on it but before going to compare them, I want to explain the implementation and working of memcpy and memmove. What is memcpy in C? The

In this article, we will learn what is void pointer in C and how we can use void pointer in our C code. If you are new in c programming, you should read this article “C pointer concept“. In the C language pointer is used to store the address of any variable or function but
void pointer in C/C++, you should know Read More »
When talking about the operators in C language, we found that C language contains a lot of operators to perform different tasks. Generally, every programmer is familiar with the functionality of pre and post-increment and decrement operators but I am here to discuss some of the important points and the problem to create clear visibility
Increment and decrement operators in C. Read More »
Many times I have found that people make mistakes when they are using signed and unsigned integers. Sometimes the basic mistake can create hidden issues and waist you’re a lot of time searching for the bugs. I know, everybody is aware of the signed and unsigned integer but still, they are making mistakes that’s why

Previously when C99 had not introduced flexible array people used the technique of struct hack to create a flexible length member. The struct hack technique gives permission to the user to create a variable length member in the structure. In the struct hack techniques, we need to create an array whose length is 0 (some

flexible array member introduced in C99. This feature enables the user to create an empty array in a structure. The size of the empty array can be changed at runtime as per the user requirements. But this empty array must be declared as the last member of the structure and the structure must contain at
