Question

What is the address of operator ( &)?

Answer 1

It is also a unary operator and gives the address of the operand. According to C standard “The operand of the unary & operator shall be either a function designator or an lvalue that designates an object that is not a bit-field and is not declared with the register storage-class specifier”.

Let see an example,

int data = 0; // declaration of integer variable

&data => Give the address of the data

int *pData ; // declaration of pointer

&pData => Give the address of the pointer
