The dereference operator, also known as the indirection operator, is a symbol used in programming languages to access the value stored at the memory address pointed to by a pointer. It is typically represented by the asterisk (*) symbol.

The indirection operator (or dereferencing operator) ( * ) operates on a pointer, and returns the value stored in the address kept in the pointer variable. For example, if pNumber is an int pointer, *pNumber returns the int value "pointed to" by pNumber .

Certainly! As an experienced tutor specializing in C++ Language Training and registered on UrbanPro.com, I'll explain the dereference operator (*) in C++, underlining the effectiveness of my C++ Language Training online coaching. In C++, the dereference operator (*) is a fundamental concept, especially when working with pointers. This operator is used to access the value stored at the memory address pointed to by a pointer. Let me illustrate this with an example: cpp #include <iostream> int main() { // Declare a variable and a pointer int num = 42; int* ptr = &num; // Pointer pointing to the address of 'num' // Use the dereference operator to access the value through the pointer std::cout << "Value of num: " << num << std::endl; std::cout << "Value through pointer: " << *ptr << std::endl; return 0; } In this example, ptr is a pointer that holds the memory address of the variable num. The dereference operator (*) is used to access the value stored at that memory address, which is the value of num.

What is the actual size of INT in the C language, 2 or 4 bytes?
The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
