In Go, you can pass pointers to functions to modify the original value of variables inside the function. This technique is called pass by reference, where instead of passing the value itself, the memory address (or reference) is passed. This allows the function to directly manipulate the original data, rather than working with a copy. […]

In Go, pointer arithmetic (performing operations like addition or subtraction on pointers) is not allowed. This differs from languages like C or C++, where you can manipulate pointers using arithmetic. 👉 The key reason pointer arithmetic is not allowed in Go is to prevent unsafe memory manipulation. Go prioritizes memory safety, and by disallowing pointer […]

What is a Pointer? A pointer is a variable that stores the memory address of another variable. Instead of holding a direct value, it holds a reference to a value stored elsewhere in memory. 👉 Pointers are used for efficient memory management and allow modifying variables indirectly by passing their address instead of a copy.
