Pointers

• A pointer is a variable that stores or holds the memory address of another variable.
• A pointer is a variable that stores or holds the memory address of another variable.
• A pointer is a variable that stores or holds the memory address of another variable.
• A pointer is a variable that stores or holds the memory address of another variable.
• Key Concepts of Pointers:

  • Memory Address
  • Pointer Variable
• Key Concepts of Pointers:

  • Memory Address
  • Pointer Variable
• Memory Address - is a unique identifier of computer memory location.
• Pointer Variable - it is a variable that is designed to store a memory address of a variable.
• Why Use Pointers?

  • Direct Memory Manipulation
  • Dynamic Memory Allocation
  • Passing by Reference
  • Working with Data Structures
• Why Use Pointers?

  • Direct Memory Manipulation
  • Dynamic Memory Allocation
  • Passing by Reference
  • Working with Data Structures
• Direct Memory Manipulation - it is more efficient in accessing and modifying the data in every variable.
• Dynamic Memory Allocation - it enables the programs to allocate memory during runtime.
• Passing by Reference - it allows modifying the data in the original variables and program efficiency.
• Working with Data Structures - it is essential in implementing dynamic data structures (flexibility of dynamic memory allocation).
