A data-type that holds values from -128 to 127.
signed and unsigned
It's their value range:signed char: -128..127unsigned char: 0..255
Consult your limits.h and math.h. For char it will be -128..127 or 0.255 (signed and unsigned).

signed char unsigned long int void *
AnswerAn unsigned char is a byte; its value can be between 0 and (2^8) - 1 (i.e., 0-255).
As integers, within range -128..127 if signed, 0..255 if unsigned.
What is the significance of declaring a constant unsigned integer?
There are far more than 4 integral types in C++. As of C++11, there were 27 integral types: bool char signed char unsigned char wchar_t char16_t char32_t short signed short unsigned short short int signed short int unsigned short int int signed int unsigned int long signed long unsigned long long int signed long int unsigned long int long long signed long long unsigned long long long long int signed long long int unsigned long long int
The primitive data types in C include:[signed|unsigned] char[signed|unsigned] short[signed|unsigned] int[signed|unsigned] long[signed|unsigned] long longfloatdoublelong doubleEnumerations (enum) and arrays may also be considered to be primitive types.
Basic built-in data types in the C programming language are scalar types in variations of char, int and float:char, unsigned char, signed charint, signed int, unsigned int, short, signed and unsigned short, long, signed and unsigned longfloat, doubleNamed enumerations are supported. These are weakly typed constant literals of type int. Bitfields are supported as range-limited signed or unsigned integers. Neither qualify as a type in their own right.Some dialects also support additional types, such as wide character, extra large integers or floating point scalars.The language also knows a related keyword void, which is used to express the fact that the related item has no known or no specific type. void in itself is not a type (it is rather the absence of a type).The C programming language also supports three basic aggregates: structure, union and arrays.Pointers can reference any of the scalar built-ins, enumerations, structures, unions, arrays, and the infamous void. Pointers are viewed as a data type by many.Other members of the C family of languages also support class and interface types and strongly typed enumerations.
There are a number of things that could be meant by a signed watch. It could be a watch with a signed face by the artist.
