char *name="32000"; What will be sizeof(name) return?
-
4 - it is the size of the pointer
-
5 - it is the number of characters in the string that the pointer points to
-
4 - it is the size when 32000 is stored as integer
-
1 - it is the size of a character variable
The variable name is declared as a pointer to char (char *name). The sizeof operator returns the size of the pointer type itself, which is 4 bytes on a 32-bit system or 8 bytes on a 64-bit system. The stored answer assumes a 32-bit environment.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) 4 - it is the size of the pointer
This option is correct. The sizeof operator returns the size in bytes of the variable or data type. In this case, name is a pointer to a character (char*), so sizeof(name) will return the size of a pointer, which is typically 4 bytes on most systems.
Option B) 5 - it is the number of characters in the string that the pointer points to
This option is incorrect. sizeof(name) does not return the length of the string that name points to. It only returns the size of the pointer itself.
Option C) 4 - it is the size when 32000 is stored as an integer
This option is incorrect. The value assigned to name is a string literal, not an integer. The size of an integer would depend on the specific system and compiler, but it is not relevant to the size of name.
Option D) 1 - it is the size of a character variable
This option is incorrect. sizeof(name) does not return the size of a character variable. It returns the size of the pointer itself.
The correct answer is A) 4 - it is the size of the pointer. This option is correct because name is a pointer, and sizeof(name) returns the size of the pointer.
