  1. Tutorial 5, Q1. • Briefly describe the purpose and principles of program slicing.

  2. Tutorial 5, Q2 • Consider the program below. a. By inspection give the dataflow slice wrt (10,{sqs}) b What is the smallest possible slice of the program? What criterion would give this slice? • count := 0; • sum := 0; • sqs := 0; • read(x); • while( x >= 0) do • count := count + 1; • sum := sum + x; • sqs := sqs + (x*x); • read(x); • write(count,sum,sqs)
