In this problem, you will create a program that declares variables with proper block scope awareness and displays the results of accessing variables inside and outside their scope to standard output.

variable Scope

Variables can only be used within the block where they are declared.

Scope Example

int result; // Available throughout method
if (condition) {
  int temp = 10; // Only available inside if
  result = temp; // result is available outside if
}
System.out.println(result); // OK
// System.out.println(temp); // Error!

Learning Points

• Variables are only valid within their declared block
• Variables declared outside are accessible inside
• Declare variables outside blocks if needed later
