Write it using Visual Studio C Language.

Problem 1

Workers at a particular company have won a 7.6% pay increase retroactive for 6 months. Write a program that takes an employee's previous annual salary as input and outputs the amount of retroactive pay due to the employee, the new annual salary and the new monthly salary. Use a variable declaration with the modifier const to express the pay increase. Your program should allow the calculation to be repeated as often as the user wishes.

Retroactive - taking effect from a date in the past

Sample output as follows:-

Enter current annual salary: 100000

Program should return new annual salary, monthly salary, and retroactive pay.

new annual salary 107600

new monthly salary 8966.67

retroactive salary due: 3800

Problem 2

An employee is paid at a rate of $16.78 per hour for the first 40 hours worked in a week. Any hours over that are paid at the overtime rate of one-and-a-half times that. From the worker's gross pay, 6% is withheld for Social Security tax. 14% is withheld for state income tax and $10 per week is withheld for union dues. If the worker has three or more dependents, then an additional $35 is withheld to cover the extra cost of health insurance beyond what the employee pays.

a) Write a program that will read in the number of hours worked in a week and the number of dependants as input and will then output the worker's gross pay, each withholding amount, and the net take-home pay for the week.

b) Modify your program so that it allows the calculation to be repeated as often as the user wishes. User enters the sentinel value -1 to terminate the program. Save this with a different filename from part (a).

Problem 3

The following flowchart contains a series of questions to determine what kind of haircut to get. Write a program that asks the questions to the user and outputs the recommended haircut.
