Question

In the statement int *ptr;, what does the keyword "int" represent?

A) Initialization
B) Pointer type
C) Integer value
D) Memory address

Answer 1

The keyword "int" in the statement int *ptr; is used to specify the Pointer type, indicating that ptr is a pointer to an integer.

Step-by-step explanation:

In the statement int *ptr;, the keyword "int" represents Pointer type. It indicates that the pointer ptr is meant to point to an integer. When we declare a pointer, in this case, an integer pointer, the type keyword specifies the type of data the pointer is expected to point to. It is not initializing the pointer, specifying an integer value, nor providing a memory address. Instead, it is declaring the variable ptr as a pointer to an integer type, which means that this pointer will hold the address of a variable of type int.
