Size of unsigned char array c.The sizeof operator returns the size in bytes of its operand. Whether the result of sizeof is unsigned int or unsigned long is implementation defined—which is why the declaration of malloc above ducked the issue by omitting any parameter information normally you int main( int argc, char argv ) sizeofxy(xy) the problem is that sizeofxy prints size of xy struct.

This cant be done with pointers alone. 4 isnt the size of the string, because samplestring isnt a string. Its a char, whose size is (on your platform) 4, divided by 1 (size of char) is, correctly, 4.
