Understanding Pointers In C By Yashwant Kanetkar Free Pdf 1763 (2027)

Yashavant Kanetkar is a household name in the Indian programming community and globally recognized for his ability to simplify complex concepts. While his magnum opus is arguably Let Us C, his dedicated book on pointers is considered essential reading for anyone who wants to move beyond basic syntax.

The book does not assume you are an expert. It starts from the very basics—what a memory address is—and gradually builds up to advanced concepts like dynamic memory allocation, pointers with arrays, and pointers to functions. Yashavant Kanetkar is a household name in the

  • realloc: preserves existing contents up to min(old,new); returns new pointer or NULL (old remains).
  • Memory leaks & double free: avoid forgetting free and avoid freeing same pointer twice.
  • Alignment and sizeof: allocate using sizeof *p rather than sizeof(int) for safer refactoring.

  • Dereference: *p yields the object pointed to.
  • Address-of operator: &x returns address of x.
  • Size: sizeof(pointer) depends on architecture (commonly 4 or 8 bytes).

  • Swap using pointers:
  • Dynamic array:
  • Function pointer:

  • Pointer declaration examples:

    Dynamic allocation idioms:

    const variations:
