Scope in Nested Blocks

In this problem, you will create a program that verifies the difference in variable scope inside and outside a nested block (if block), calculates the sum of an outer and inner variable, and displays the results to standard output.

Learning Objective: Understand variable scope in nested blocks

Overview

Variables declared in an outer block can be used in inner blocks, but variables declared in inner blocks cannot be used outside. Verify this behavior.

Specifications

• Initialize variable outer with 100 in main method
• Inside an if block, initialize variable inner with 50 and calculate the sum of outer and inner
• Output the sum inside the if block
• Output outer's value outside the if block

Output Format

Sum: 150
Outer: 100
