This is the "Address of" operator. It extracts the hexadecimal memory address of a variable.
The publisher sells a DRM-protected PDF directly. The price is around ₹250–400 INR ($3–5 USD). This is the edition, fully searchable, with high-resolution diagrams. You pay once and download immediately.
"Instead, you can use a special kind of catalog that tells you exactly where the book is located. This catalog is like a map that shows you the address of the book. If you want to find the book, you can simply look up its address in the catalog and go straight to that location.
A pointer is simply a special variable that stores the memory address of another variable. You declare a pointer by placing an asterisk ( * ) before its name. pointers in c by yashwant kanetkar pdf free download new
Before you search for the PDF, it is important to understand what makes Kanetkar’s approach unique. Unlike dry, academic textbooks, Kanetkar writes in a conversational, example-driven style.
Every variable you create in C is stored in a specific location in your computer's RAM, known as a . A pointer is simply a variable that stores the memory address of another variable.
It finds an empty memory box (for example, box number 6482520 ). It labels that box age . This is the "Address of" operator
One of C's unique features is the ability to perform math on pointers. However, pointer arithmetic does not work like standard math. It is entirely dependent on the data type the pointer references.
The book's provides a complete picture of its scope:
#include int main() int age = 25; // A regular integer variable int *ptr; // Declaration of an integer pointer ptr = &age; // ptr now stores the memory address of age printf("Value of age: %d\n", age); printf("Address of age: %p\n", (void*)&age); printf("Value stored in ptr: %p\n", (void*)ptr); printf("Value pointed to by ptr: %d\n", *ptr); return 0; Use code with caution. Breaking Down the Code The price is around ₹250–400 INR ($3–5 USD)
operation = mul; // switch to `mul` apply(operation, 4, 5); // 20
If you want to learn more about pointers in C, I recommend checking out Yashwant Kanetkar's book "Let Us C" or searching for online resources. With practice and patience, you'll become a master of pointers in no time!
