What is a long integer constant?
An integer constant is a decimal (base 10), octal (base 8), or hexadecimal (base 16) number that represents an integral value. Use integer constants to represent integer values that cannot be changed.

What is a long constant?
A long constant is written with a terminal l (ell) or L , as in 123456789L ; an integer constant too large to fit into an int will also be considered long. Unsigned constants are written with a terminal u or U, and the suffix ul or UL indicates unsigned length.
Is Long Long an integer?
7 answers. long and long int are identical. So are long long and long long int . In both cases, the int is optional.
What is a character constant in C?
Character constants and strings in C: A character constant is a single alphabet, single digit, or single special symbol enclosed in single quotes. The maximum length of a character constant is 1 character. String constants are enclosed in double quotes.
Is 0 an octal integer constant?
An octal constant consists of the prefix 0 optionally followed by a sequence of digits from 0 to 7 only. A hexadecimal constant consists of the prefix 0x or 0X followed by a sequence of decimal digits and the letters a (or A) to f (or F) with values from 10 to 15 respectively.
What are the limits of the int data type?
The INTEGER data type stores integers ranging from -2,147,483,647 to 2,147,483,647 to 9 or 10 digits of precision. The number 2,147,483,648 is a reserved value and cannot be used.
Can a long long be an int in C++?
long long is not part of the C++ standard but is only (generally) supported as an extension. This affects the type of literals. Decimal integer literals without any suffix are always of type int if int is large enough to represent the number, long otherwise.
What are the integer bounds for unsigned int?
UINT_MAX. Maximum value for a variable of type unsigned int. 4294967295 (0xffffffff) LONG_MIN. Minimum value for a variable of type long. -2147483648. LENGTH_MAX. Maximum value for a variable of type long. 2147483647.
What is the longest unsigned integer in C?
Unsigned long long integer type. Contains at least the range [0, +18,446,744,073,709,551,615]. Specified since the C99 version of the standard. A real floating-point type, often called a single-precision floating-point type.
Why is the integer constant too big for the “long” type?
Closed 9 years ago. Writing a simple program for an Euler project problem. He refuses to compile because “the integer constant is too large for the ‘long’ type”, even though it should be within the size limits of an unsigned long . Using the dev-c++ compiler.
