i have finished writing my program, but teacher want me to write a checkbook balancing program of a user's account. It has to use getline () to read a line, which will contain either the word "withdrawal" or "deposit". After reading each pair of line, the program should compute and print new balance. I think i need to declare a variable to hold the running balance. The program must warn when the user if the withdrawal exceeds the balance.
*input should be somthing like this:

1.deposit
2.100
3.withdrawal
4.12.34
5.withdrawal
6.49.00
7.deposit
8.7.01

*OUT PUT of the program should print something like:

balance:100.00
balance:87.66
balance:38.66
balance:45.67

Help with what? You need to explain whatever problem you are having.

You also need to format your code because, as posted, it's unreadable.

The program must warn when the user if the withdrawal exceeds the balance.
*input should be somthing like this:

1.deposit
2.100
3.withdrawal
4.12.34
5.withdrawal
6.49.00
7.deposit
8.7.01

*OUT PUT of the program should print something like:

balance:100.00
balance:87.66
balance:38.66
balance:45.67
