Scope in Nested Blocks

Learning Objective: Understand variable scope between nested blocks

Overview

Declare variables in three levels of nested blocks and verify which variables are accessible at each level.

Specifications

• Level 1: Initialize variable a with 1
• Level 2: Initialize variable b with 2 (inside Level 1)
• Level 3: Initialize variable c with 3 (inside Level 2)
• At Level 3, output sum of all variables
• At Level 2, output sum of a and b
• At Level 1, output only a

Output Format

Level 3: a+b+c = 6
Level 2: a+b = 3
Level 1: a = 1
