Updating Master Files

hagfish88 (20)
Hello. I am in a C++ class and am working on a problem that is in our book where we need to make pseudocode and then translate it into C++, this chapter is on updating a master file from a transaction file. the pseudocode that i have completed and was told by my instructor was correct is

any help translating this into C++ is very much welcome.

If you got that far in pseudocode I know that you have something to show us in C++ code. Have you attempted anything yet?

I posted this right before I went to bed and i just got back from work. I have the declarations figured out but besides comparing similar statements to examples. No i havent attempted this code yet. Il post again in a short bit with some completed things.

this is just up to the first while statement i believe.

    return EXIT_SUCCESS;
}


updated code. stuck on the else if and i just realized that the output statments need to be directed to the MasterFile and im not sure how to send it specifically to that file.

ok i think this is the completed code but i am still getting errors on the else statements. The errors say that there is supposed to be a ; before the else but I cant figure out where Im still messing up. Any help would be much appreciated.
Peter87 (11234)
These errors are easier to find if you make sure to indent the code properly. You have an opening bracket on line 42 but no closing bracket.
hagfish88 (20)
I thought that i put the "end if" closing squigly mark before the TransactionFile is read on line 64. Let me try that and see if it works.
Peter87 (11234)
I guess you are right. I wasn't looking at the whole code. I just assumed the else on line 44 was supposed to belong to the if statement on line 41.

So the problem is that you have an else without an if. Maybe you don't want the else on line 44 at all. Only the if. I don't know for sure because I have only looked at the syntax without trying to understand the program logic.

I fixed the bracket problem and was getting garbage values when the program compiled. So I changed the int number values to double. Now its executing and saying that record 1 and record 5 are not in my source files. Didnt have that problem for the other values in the extra files so im not sure why that is giving me trouble but here is another updated version.
