More on Scope

• The scope of a variable is the set of places in which it can be referenced. A variable can be declared only once within a method. We call this a local variable.

• The scope of a local variable of a method is the sequence of statements following it

• Example: // Set y to the maximum of p and -p

  public void sety(int p)
  

{int x;

x= p;

if (p > -p)

x= -p;

y= p;

}
