If your problem is with the actual programming, you need the input of the other people here; if your problem is with the logic you need mine.

The trouble is, I don't know how much you already know, and, if you put in things you haven't covered yet, your tutor will know that it didn't come out of your own head. The fact that you refer to the structure definition as a chart suggests you haven't covered them yet, and maybe you haven't covered file input/output either. If both of those is the case, you are probably being expected to store the input in arrays.

Or is your problem in understanding the book keeping terms? I don't know.

However in a kind of pigoen English rather than C:

define array of maybe twenty integers for account numbers
define array of maybe twenty floats for transaction ammounts, etc.

choice = 'x'
index = 0;

index = 1

until user wants to quit, or arrays are full, and you can't accept any more input
{
get user's choice

if user wants to enter transaction
{
get account number
store number in account_array[ index ]
get amount
store number in amount_array[ index ]

==== etc ======

when finished getting input for this transaction increment index by one
}

if( user wants to see journal )
{
use data you have got stored in the arrays to show jounal entries,
probably using the printf function to do it.
}

if( user wants to see balance sheet )
{
similarly, use data in arrays to do it, and use printf to display
balance sheet on screen
}

if( user wants to quit )
quit
}

end of program
