New Nintendo accessory can trick you into exercising! long int is the same as long (just as short int is the same as short). So are long long and long long int.In both cases, the int is optional.. As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long.. The following table lists the permissible combinations in specifying a large set of storage size-specific declarations. Usually, programming languages specify the range values for given data-type. The long double type was present in the original 1989 C standard, but support was improved by the 1999 revision of the C standard, or C99, which extended the standard library to include functions operating on long double such as sinl() and strtold().. Long double constants are floating-point constants suffixed with "L" or "l" (lower-case L), e.g., 0.333333333333333333L. Data type in C++is a set of values and is determined to act on those values. To make an integer constant of type long long int, add the suffix LL' to the integer. https://software.intel.com/en-us/articles/size-of-long-integer-type-on-different-architecture-and-os. All variables use data-type during declaration to restrict the type of data to be stored. Data type is a system for defining various properties of data stored in memory. In C, each variable has a specific data type, where a data type tells us the size, range and the type of a value that can be stored in a variable. It is used to modify the size of the built-in data type in C++. Values may be negative, positive, or zero. Therefore, we can say that data types are used to tell the variables the type of data it can store.

The short is usually smaller, the long can be larger or the same size as an int and finally the long long is for handling very large numbers.long long is an integer type which is at least 64-bit    (8 byte )wide. In some of the systems it behaves like an int data type or a long long data type as follows: Well it also varies from compiler. Derived data types : Derived data types are nothing but primary datatypes but a little twisted or grouped together like array , stucture , union and pointer . But there is a catch, the size of “long” data type is not fixed unlike other data types. For this reason, int variables can be different depending what type of computer you are using. As you can see, the size of long int and long double variables are larger than int and double variables, respectively. You can alter the data storage of a data type by using them. Number types are divided into two groups: Integer types stores whole numbers, positive or negative (such as 123 or -456), without decimals. In C, signed and unsigned are type modifiers.
