The 4 C++ Type Modifiers: short, long, signed and unsigned

short type Modifier

We can use short for small integers, ranging from -32,767 to 32,767. Short is equivalent to 'short int’.

// small integer
short a = 12345;

long type Modifier

We can use long for large integers, ranging from in the range -2147483647 to 2147483647. Long is equivalent to ‘long int’.

// large integer 
long b = 123456;

signed Modifier

Signed variables can hold both positive and negative integers including zero. By default, integers are signed. signed can only be used with int and char types.

// positive valued integer 
signed int x = 23;

// negative valued integer
signed int y = -13;

// zero-valued integer
signed int z = 0;

unsigned type Modifier

The unsigned variables can hold only non-negative integer values. unsigned can only be used with int and char types.

// positive valued integer
unsigned int x = 2;
unsigned int y = 0;
