long is short name for long int bytes bits -2147483648 to 2147483647 u n s i g n e d l o n g A double spaced integer without any sign bytes bits to , , , signed long A double spaced integer with sign bytes bits -2147483648 to 2147483647 The above table clearly shows that an integer type accepts only bytes of data whereas a long int accepts data that is double this size i.e., bytes of data. So, we can store more digits in a long int. (long is a modifier and int is a fundamental data type) char type Table .

× - long double signed more precision fractional value bytes bits . × - to . × - Memory allocation is subjected to vary based on the type of compiler that is being used. Here, the given values are as per the Turbo C++ compiler.
Dev C++ provides some more space to int and long double types. Following Tables . shows the difference between Turbo C++ and Dev C++ allocation of memory. Table .
