Practice Exercise: Control Structures(selection) Objective: Be able to employ the if, if...else, if...else...if The general form for the if statement is: if (expression) statement ...; else ...; Compound statement blocks are surrounded by {}. 1. Simple if statement: Given that an variable item named workHours has been initialized or input, determine whether it is greater than 40, and print the message "Pay Overtime!". 2. Two-Way Selection: Given a variable item named workHours, calculate regularHours and overtimeHours. RegularHours are those workHours less than or equal to 40. OvertimeHours are those workHours exceeding 40. 3. Complex if statements: Given data items for workStatus, payPlan, annualSalary, and payYTD (pay for the year to this date). For workStatus of 'A' (for active) and payPlan is 'M' (for monthly), compute currentPay = annualSalary / 12; then add currentPay to payYTD. 4. Multiple Selection (nested if): Compute tax on currentPay according to the following rules: For currentPay <= 2000.00 tax is 0.00; for currentPay from 2000.00 to 2500.00, tax is 15% of currentPay over 2000.00 (first 2000.00 not taxed); and for currentPay over 2500.00, tax is $75 plus 20% of CurrentPay over 2500.00.
