Homework- Choose one or do both
- Write a program where the user inputs their monthly budget. The loop should then ask the user to input each of their monthly expenses. These expenses should be kept in a running total. The final output should display if the user is over or under their budget for the month, and by how much.
- Write a program where a random number is generated. Then the user tries to guess the number. If they guess too high display something to let them know, and same for if they guess a number that is too low. The loop must iterate until the number is guessed correctly.
