# A bug collector collects bugs every day for five days. Write a program that keeps a running
# total of the number of bugs collected during the five days. The loop should ask for the
# number of bugs collected for each day, and when the loop is finished, the program should
# display the total number of bugs collected.

# Write a program that calculates the amount of money a person would earn over a period
# of time if his or her salary is one penny the first day, two pennies the second day, and
# continues to double each day. The program should ask the user for the number of days.
# Display a table showing what the salary was for each day, then show the total pay at the
# end of the period. The output should be displayed in a dollar amount, not the number of
# pennies.

# Write a program with a loop that asks the user to enter a series of positive numbers. The
# user should enter a negative number to signal the end of the series. After all the positive
