Example

// assigning a signed short to its minimum value
short s = -32768;

// assigning a signed short to its maximum value
short s = 32767;

// assigning a signed int to its minimum value
int i = -2147483648;

// assigning a signed int to its maximum value
int i = 2147483647;

// assigning a signed long to its minimum value (note the long postfix)
long l = -9223372036854775808L;

// assigning a signed long to its maximum value (note the long postfix)
long l = 9223372036854775807L;

It is also possible to make these types nullable, meaning that additionally to the usual values, null can be assigned, too. If a variable of a nullable type is not initialized, it will be null instead of 0. Nullable types are marked by adding a question mark (?) after the type.

int a; //This is now 0.
int? b; //This is now null.
