C++ fundamental (primitive) types:

• bool
• char
• int
• float
• double

Optionally:

• void

Additional qualifiers for the primitive types:

• signed
• unsigned
• short
• long

Using the two together:

bool: 1 byte (Range: true or false)

signed char = char: 1 byte, (Range: -128 to 127)

unsigned char: 1 byte (Range: 0 to 255)

short = short int = signed short int: 2 bytes (Range: -2^15 to 2^15-1)

unsigned short = unsigned short int: 2 bytes (Range: 0 to 2^16-1)

long = long int = signed long int = signed int = int: 4 bytes (Range: -2^31 to 2^31-1)

usigned long = unsigned long int = unsigned int: 4 bytes (Range: 0 to 2^32-1)

float: 4 bytes (Cannot be unsigned, short, long. Range: 3.4e-38 to 3.4e+38, 7 digits)

double: 8 bytes (Cannot be unsigned, short. Range: 1.7e-308 to 1.7e+308, 15 digits)

long double: 10 bytes (Range:)
