C Program.

Q2: (Weekly Pay Calculator) (25 points) Develop a program that calculates weekly pay for group of hourly workers. Design appropriate prompts and outputs of your own design. The program should prompt for the number of hours worked in the week and the hourly rate. Generate the gross weekly pay and print it. Hours over 40 should be paid at time and a half hourly rate. Use a sentinel value to terminate data entry Note: For this program, it is acceptable to use float or double data types for monetary units. However, you should never use float and double data types for monetary unit. Bonus (5 points). Write a small program that illustrates the dangers of using floats (or doubles) for monetary units. Q3: (Bar Charts) (25 Points) Write a program that reads in a series of integers in the range of 1 to 40, with the first number indicating how many integers follow it. Print out a bar chart of the numbers entered. For example, if the following is entered at a prompt Enter integers between 1 and 40 (first number indicates how many there are): 3 10 13 9 You should output the following Q4: (Approximating ) (25 points) The value of can be approximated with the infinite series as follows 1 3 5 7 9 11 Write a program that determines how many terms in takes using the above infinite series to approximate to 3.14159. You can state the answer to this question in the word document you submit, if you obtain the answer through trial and error. Bonus (5 points): Your program should stop itself when the precision is met and output the following It took n terms to approximate pi to 3.14159 Hint: Think about a numerator and a denominator. You learned in a previous homework how to generate odd number sequences. Pay close attention to the sign of each term. Casting: You can eliminate all numbers beyond the 5th decimal position using casting, such as int a = (int)(314159265 * 100000). Here a float is being multiplied by an integer, with the result being a float. The decimal point has been moved 5 places to the right. Use (int) to "cast" that into an integer, truncating all the decimals of the new number, resulting in the new number 314159
