Size Of Pointer In Cpp

Size Of Pointer In Cpp - sizeof is an operator integrated in the C++ language that returns the size in bytes of its argument. For non-dynamic data types, this value is a constant. Therefore, for example, sizeof(char) is 1, because char has always a size of one.

;On a modern PC the size of a pointer depends on the size of the native word length (32 or 64 bits). But there's nothing to say that a pointer have to be a specific length or size, or even that the size of pointers have to be uniform on a single platform using a single compiler. The difference is because the size of an int is 4 bytes in a 64-bit system. Note: You may not get the same results when you run the program. This is because the address depends on the environment in which the program runs. ... Working of C++ pointers. Changing Value Pointed by Pointers.
