address of pointer is stored is of type ” int long” which means size is 4 (depends upon the processor 16 bit or 32 bit) thats why it is returning size is 4 in above c code snippet.
hope this helps you .

@Stuart: actually d size of every pointer in c is of 4 bytes, whether it is char or int doesn’t make any difference…

u all guys are not familiar with C.
so please go to library and read some good book on C.

@Stuart, @Steven
> Are you talking about a 4 bit byte in your answer?

i think steven has a typo, he meant bytes there instead of bits.

@Stuart, the C standard does not define the number of bits in a byte, but states that sizeof(char) will ALWAYS be 1, regardless of bits per byte.

sizeof(char*) is not defined by the standard. It is equal to the size of any other pointer, ie sizeof(void*), which on modern operating systems and computers will be 4 or 8 BYTES.

Using a global integer to store return values in is ridiculous, and why would you return a pointer to it? You will not be employed by a reputable company by writing such code.

43.What is the value of sizeof(a) /sizeof(char *) in C code snippet below
char *a[4]={“sridhar”,”raghava”,”shashi”,”srikanth”}; explain

Are you talking about a 4 bit byte in your answer?
Actually a char is 8 bits – 1 byte.
the size of char * is 8 bits 1 byte as well.
The sizeof operator returns the size in bytes of its operand.

The answer is still the same but the explaination is incorrect.
