Storing transaction using vector and then recall that transaction

Elshot (9)
Is there anyone can do this for me I stuck in this assignment I'm getting more confuse doing it and I don't know what to do.

Here it is.

Requirement 1
The program MUST provide a user interface and functionality for users
to convert between Fijiian Dollars, Vanuatu Vatu and Samoan Tala.

There must be an option to convert from Fijiian Dollars to Vanuatu Vatu and
vice versa.

There must be an option to convert from Fijiian Dollars to Samoan Tala and
vice versa.

There must be an option to convert from Samoan Tala to Vanuatu Vatu and
vice versa.

Requirement 2
The program MUST provide a user interface option and functionality
to recall all the previous transactions since the start of the program.

Requirement 3 The program SHOULD start with an internal opening balance of
FJD$10,000, V10,000,000 and T1,000,000. Each transaction should increment or
decrement the internal balances. Transactions that result in an internal balance
that is less than 0 should be disallowed

Here is my coding for requirement 1 only requirement 2 and 3 that I still stuck in it

Hello Elshot,

Your other program http://www.cplusplus.com/forum/beginner/234841/ covered requirement 1 much better.

As it is your code now does not show options "e" of "f" until all the other options have been displayed and at least one of them chosen before you proceed to the set of choices.

Lines 19 - 31 print out a nice piece of information after the you should loose the pause and display all of the choices at one time, so the user knows what to choose from.

Now that you program is smaller it would also be a good time to shorten what you do have.

In place of all the if statements you could use a switch/case and within that when you ask the user how much to convert you could write one function that will ask for the correct input and return the amount for use.

Hope that helps,

Andy
