How many bytes is unsigned long

Websize_t • Computer memory keeps increasing • 32-bit int was enough in the past to for data length • But now it is not. size_t: • Unsigned integer • Type of the result of sizeof operator • Can store the maximum size of a theoretically possible object of any type • 32-bit, or 64-bit WebThe size of both unsigned and signed long integers depends on the type of compiler that we use. The size is typically about 32-bits or 4 bytes on a 16/ 32-bit compiler. Yet, it varies depending on what compiler we are using. There is no specification of the data types sizes according to the C standard, except the character.
