Hello,
This should be pretty straightforward.
First, you need to create two data structures in memory. They will be the same structures, but one will be the master file data, and the other will be the transaction file.
Couple things for you to think about:
* Array or linked list?
* Look up the string compare function to see how to compare account numbers
* How will you handle bad data in the transaction file?
* When the program is done, write out the memory to a flat file.
Go ahead and code this out. If you need more help, please show us some psuedo code, and let us help. We cannot go too much further in assistance, as it would violate DaniWeb homework policy.
