Question

What is Indirection or Dereference Operator ( * )?

Answer 1

t is a unary operator that is used in the declaration of the pointer and accesses a value indirectly, through a pointer.  The operand of the indirection operator should be a pointer and the result of the operation is value addressed by the operand (pointer).

Let see an example,

int *iPtr; // Use of indirection operator in the declaration of pointer

a = *iPtr; //Use of indirection operator to read the value of the address pointed by the pointer

*iPtr = a; //Use of indirection operator to write the value to the address pointed by point
