The address of the first byte of reserved space is assigned to the pointer ptr of type int.

WebThe malloc line allocates a block of memory of the size specified -- in this case, sizeof(int) bytes (4 bytes). The sizeof command in C returns the size, in bytes, of any type. The code could just as easily have said malloc(4), since sizeof(int) equals 4 bytes on most machines. Using sizeof, however, makes the code much more portable and readable.
