How do you get the value of a pointer variable?

Steps:

1. Declare a normal variable, assign the value.
2. Declare a pointer variable with the same type as the normal variable.
3. Initialize the pointer variable with the address of normal variable.
4. Access the value of the variable by using asterisk (*) – it is known as dereference operator.

How do you get the memory address of a variable in C++?

In c++ you can get the memory address of a variable by using the & operator, like: cout << &i << endl; The output of that cout is the memory address of the first byte of the variable i we just created.

What is pointer explain with example to print the address of variable using pointer?

A pointer is a variable that stores the address of another variable. Unlike other variables that hold values of a certain type, pointer holds the address of a variable. For example, an integer variable holds (or you can say stores) an integer value, however an integer pointer holds the address of a integer variable.

How do I find the address of a character in C++?

2) The address of the string “hello” is displayed by: char *st = “hello”; cout << (int)st << endl; this displays the address of the pointer, as above in 1). If you wanted to see assigned 0, then you would display the value of the char*, as above in 2).

What operator is used to get the memory address of a variable?

What Does Address-of Operator (&) Mean? An address-of operator is a mechanism within C++ that returns the memory address of a variable. These addresses returned by the address-of operator are known as pointers, because they “point” to the variable in memory.

How do you print the address of a variable in C?

To print the memory address, we use ‘\%p’ format specifier in C. To print the address of a variable, we use “\%p” specifier in C programming language. There are two ways to get the address of the variable: By using “address of” (&) operator.
