Part 1: Functions and the Call Stack Before we can understand pointers and memory management in C, we need to understand how functions work and what happens behind the scenes when your program runs. This foundation will make everything else click int...
Recursion in C Recursion in C is a technique where a function calls itself in order to solve a problem. Each time the function calls itself, a new stack frame is created for that call, containing its own set of local variables. This continues until a...
Pointers in C are a fundamental and powerful concept used for memory management. A pointer is essentially a variable that stores the memory address of another variable. This allows for direct access and manipulation of memory locations, which can lea...
Here are 10 C programming exercises that focus on pointers: Swap using Pointers: Write a program to swap the values of two integers using pointers. Array Manipulation: Create an array of integers and write a program to find the sum and average of t...
Let's explore the differences between a pointer to a constant, a constant pointer, and a constant pointer to a constant in C with detailed code examples: Pointer to a Constant: A pointer to a constant is a pointer that points to a constant value. T...
Function pointers in C are pointers that point to functions. In other words, while a regular pointer holds the address of a variable, a function pointer holds the address of a function. Function pointers are used for dynamic function calls - the func...
