Understanding Pointers in C Pointers are variables that store the memory address of another variable. They are used extensively in C for various purposes, such as accessing array elements, passing arguments to functions by reference, and dynamic memory allocation. Pointers provide a way to manipulate...
Before you proceed this section, we recommend you to checkC dynamic memory allocation. Sometimes, the number of struct variables you declared may be insufficient. You may need to allocate memory during run-time. Here's how you can achieve this in C programming. Example: Dynamic memory allocatio...
int * a, b, c; // a is a pointer, b and c are integers. Assigning to pointer variables A variable with a pointer value allocates space to hold the pointer, but not to hold anything it points to. As with any other variable in C, a pointer-valued variable will initially contain ga...
in languages like c and c++, the size of the array should be fixed at compile-time unless you're dealing with dynamic memory allocation. however, in some modern languages, arrays can be dynamically resized, but those aren't technically arrays of pointers in the c/c++ sense. how do i ...

They provide important support for dynamic memory allocation, are closely tied to array notation, and, when used to point to functions, add another dimension to flow control in a program. Pointers have long been a stumbling block in learning C. The basic concept of a pointer is simple: it ...
"Heap" memory, also known as "dynamic" memory, is an alternative to local stack memory. Local memory (Section 2) is quite automatic � it is allocated automatically on function call and it is deallocated automatically when a function exits. Heap memory is different in every way. The progra...
