Before we start with basics of pointers, it is strictly recommended to go through the concepts of pointers from the Learn C Online (Click here). We have attempted to cover pointers in the most simplest manner possible. But, it will be impossible for you to grasp the knowledge of the ...
Pointers to Pointers It is possible and often useful to create pointers to pointers. This technique is sometimes called ahandle, and is useful in certain situations where the operating system wants to be able to move blocks of memory on the heap around at its discretion. The following example...
Pointers: Common Bugs Bug #1 - Uninitialized pointers One of the easiest ways to create a pointer bug is to try to reference the value of a pointer even though the pointer is uninitialized and does not yet point to a valid address. For example: int *p; *p = 12; The pointerpis uninitia...
Passing a pointer to an array to a function C program Pointers in C - C program Linked Lists in C - C program Recursion in C What is an embedded system ? An embedded system is a computer system designed to perform one or a few dedicated functions often with real-time computing. C ...
For several subjects, this tutorial will only provide pointers to other resources dedicated to each topic (especially Sparkfun tutorials as I find them quite complete). What is KSP? Kerbal Space Program is a game where you build rockets and they fly them. If you don't know it, you may ...
Structures are great for representing collections of related attributes, and they take very little effort to use! We'll cover more involved uses of structures, such as arrays of structures and pointers to structures, in an upcoming post.
Memory Management: While arrays demand manual memory management when dynamically allocated (using pointers and new/delete), std::vector handles this automatically, reducing the risks of memory leaks or access to deallocated memory. Insertions and Deletions: Inserting or removing elements in the middle ...
POINTERS As you know, every object in the program (variable, procedure, subroutine, etc.) is assigned one specific memory address. When declaring a variable in the program, the compiler automatically assigns it a free RAM location. During programming, these addresses are kept hidden from programme...

Pointers in Go allow us to reference a memory location that stores a value of a particular type. We use pointers because sometimes we need to pass large structures by reference instead of by value for efficiency. In simple terms, a pointer contains the memory address of a value. We define...
