Dangling Pointer in C Language: The most common bugs related to pointers and memory management in C Programming Language is Dangling/Wild Pointers. Sometimes as a programmer, we forgot to initialize the pointer with a valid address, and when we do so, then this type of uninitialized pointer is known asContinue Reading

Passing Structure as a Parameter to a Function using Call by Value in C Language: Let us understand how to pass a structure as a parameter to a function using the call by value mechanism in C Language. For a better understanding of this let us first create a structureContinue Reading

Passing Array as a Parameter to a Function in C Language: Let us understand this directly with an example. Please have a look at the following example. As you can see in the below code, the main function is having an array of size 5 and it is also initializedContinue Reading

Let us understand How to Access a Structure using a Pointer in C Language with an example First, we will see how to access the structure using normal variables, and then we will see how to access the structure using pointer variables. Please have a look at the following code example.Continue Reading

Error Handling in C Program: There is no direct support for Error Handling in C language. However, using the return statement in a function, there are few methods and variables defined in error.h header file that can be used to point out the error.  A programmer has to prevent errors in theContinue Reading

What is a File? A file is the name of a physical memory location in the secondary storage area. The file contains a sequence of bytes of data in the secondary storage area in the form of an unstructured manner. In the implementation, when we were required to interact withContinue Reading

Dynamic Array: Static array variables are fixed in size. They are linked in the data area or stack area or in the const area depending on the declaration. Now, this element group is fixed and cannot be changed. To affect this shortcoming dynamic arrays are often defined. Dynamic array isContinue Reading

Memory Management in C In the C Programming language, we are having two types of Memory Management Static Memory Management in C Language Dynamic Memory Management in C Language Note: Dynamic Memory Allocation related all predefined functions are declared in <malloc.h>, <alloc.h>,<stdio.h> Dynamic Memory Allocation Related Predefined Functions in C Language:Continue Reading

Typedef in C Language: It is a Keyword, by using this keyword, we can create a user-defined name for an existing data type. The typedef is a keyword in the C programming language which is used to provide meaningful names to already existing variables inside a C program. In short,Continue Reading
