Design and develop a Visual Basic program to compute the net monthly pay for an employee. The employee receives a base salary and 10% of the base salary as benefits, the sum of which yields the gross pay. Deductions include tax withholding at 15% of gross salary, social security at 2% of gross salary, pension contributions at 10% of gross pay, and health insurance at 8% of gross pay. The net pay is the difference between gross pay and deductions.
