1. Consider the following program \} (1) Draw the control flow graph of the program, start with Statement S1 (2) For each node, check if there are Definition, C-use or P-use for variable "low". List Definition, C- use or/and P-use for variable "low" (3) List all def-c-use pairs with respect to the variable "low". Use the format (var low, def_line_number, use_line_number) 2. Define the equivalence partitions and give one suitable test case for each partition for the following question: Input variable name: Social Number: Range 001-01-0001 to 729-99-9999 inclusive. Note: You are not required to write a complete test suite with test id, expect and actual outputs for this assignment - just the test input value is required. 30 points)
