The assignment operator is the single equal sign =.
It has this general form:
variableName = expression;
Here, the type of variableName must be compatible with the type of expression.
The assignment operator can create a chain of assignments.
For example, consider this fragment:
int x, y, z; x = y = z = 100; // set x, y, and z to 100
This fragment sets the variables x, y, and z to 100 using a single statement.
The = is an operator that yields the value of the right-hand expression.
The value of z = 100 is 100, which is then assigned to y.
