Long Data Type In C++

C++ Long Data Type ?

Long data is a 64-bit signed two's complement integer.

➦ The minimum value is -9,223,372,036,854,775,808 and maximum value is 9,223,372,036,854,775,807(inclusive)

➦This type is used when a wider range than int is needed.

Example:
long a= 100000L, int b= 3200000L

➦ Long is a data type used in programming languages, such as Java, C++, and C#. A constant or variable defined as long can store a single 64-bit signed integer.
