Software Engineering Assignments

1.For apiece of the following documents, indicate in which phse(s) of the software life cycle it is produced final user manual, architectural design, SQA plan, module specification, line of descent code, statement of work, test plan, preliminary user annual, detailed design, cost estimate, rove plan, test report, documentation.2.Order the following tasks in terms of the waterfall model bankers acceptance testing, project planning, unit testing, requirements review, cost estimating, high level design, market analysis, dependent design, systems testing, design review, implementation, requirement specification.3.How does a phased life cycle model serve up software management?SOFTWARE METRICS1.What is McCabes cyclomatic number? Determine the equal for2.In Halsteads metrices, what is the significance of (i)operators and operands (ii)potential operands, (iii)Length (iv)Estimated length (v)Volume (vi)Potential volume (vii)Implementation Level3.How is effort and time deliberate in Halstead method?4.Why is the number of decisions + 1 an important method for calculating McCabes cyclomatic no.? (Ans It would be very time consuming to accommodate to construct the control flow graph for large programs).5.Why is monotonicity an important sign of a size or effort metric such as Halsteads effort metric? (Ans If adding more code can dumbfound the value of the effort metric to decrease, then the metrics expression is not understandable. It may also mean that the metric is manipulated).6.Why is complexity not readily measurable? (Ans Complexity is not well defined and each one has different interpretation. It is interaction between person and code that makes it herculean to define). 7.Calculate McCabes complexity on the following source code. Draw a control flow graph. Read x,y,zType = scalene If(x= =y or x= =z or y = =x) type = isosceles If(x= =y or x= =z) type equilateral If(x =y+z or y =x+z or z= x+y)) type not a triangle If(x =0 or y =0 or z
