What is long data type example?

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. An integer is a whole number that does not include a decimal point. Examples include 1, 99, or 234536.

What is the range of long double?

Float variables typically requires 4 byte of memory space. Double Floating Point: Double Floating Point data type is used for storing double precision floating point values or decimal values….Long.

Data Type Size (in bytes) Range
short int 2 -32,768 to 32,767
long double 12
wchar_t 2 or 4 1 wide character

What’s a long value?

long: The long data type is a 64-bit two’s complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1.

What is the difference between long and long long in C?

It is clear from the above discussion that the main difference between long and long long is their range. Also, standard mandates minimum ranges for each, and that long long is at least as wide as long.

What is primary data type in C?

char: The most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers. int: As the name suggests, an int variable is used to store an integer. float: It is used to store decimal numbers (numbers with floating point value) with single precision.
