PROGRAM 1:

Write a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is $4,000; for married people, the standard exemption is $7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is:

• Between $0 and $15,000, the tax rate is 15%.
• Between $15,001 and $40,000, the tax is $2,250 plus 25% of the taxable income over $15,000.
• Over $40,000, the tax is $8,460 plus 35% of the taxable income over $40,000. Prompt the user to enter the following information:
• Marital status
• If the marital status is “married,” ask for the number of children under the age of 14
• Gross salary (If the marital status is “married” and both spouses have income, enter the combined salary.)
• Percentage of gross income contributed to a pension fund Your program must consist of at least the following functions:
• Function getData: This function asks the user to enter the relevant data.
• Function taxAmount: This function computes and returns the tax owed.

To calculate the taxable income, subtract the sum of the standard exemption, the amount contributed to a pension plan, and the personal exemption, which is $1,500 per person. (Note that if a married couple has two children under the age of 14, then the personal exemption is $1,500 ∗ 4 = $6,000.)

Since your program handles currency, make sure to use a data type that can store decimals with decimal precision of 2.

​

PROGRAM 2:

Instructions

You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that a student may not have a middle name.) 

Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name in a variable and must consist of a function that takes as input a string, consists of a student’s name, and returns the string consisting of the altered name. Use the string function find to find the index of ,; the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.

PROGRAM 3:

Instructions

Write a program that prompts the user to enter a string. The program outputs the sum of the values (collating sequence or ASCII value) of the characters in the string. For example, if the string is "spring", then the sum of the values of the characters is 115 + 112 + 114 + 105 + 110 + 103 = 659.
