URGENT HELP (FIRST-YEAR PROGRAMMING)

[MasterKay]

I don't know how to do this thing. Please copy and paste my code and try to fix it then resend it here fixed. I tried but I cannot do this for 6 days. Please show me the full code. I am new to this programming world, I hope you understand my state.

Thank you in advance!


THIS IS WHAT I HAVE TO HAVE AS AN OUTPUT

THE FOLLOWING IS MY CODE:

    inputFile.open(filename.c_str());

if(inputFile)
{

return 0;

[Handy Andy]

Hello MasterKay,

Kiryu has given you a response that most here will give you if they were to respond.

I have shown you a place to start:
http://www.cplusplus.com/forum/beginner/214897/#msg999629 and
http://www.cplusplus.com/forum/beginner/214897/#msg999647
yet I see by your code that you have made no attempt to change anything. I will help you figure this program out, but you need to make some attempt to show that you are tying. If you want to have someone else write the program for you try a Google search on the parts of the program you do not understand.

Some parts of your program are good and will work others need a little work, but your sort functions need a total rework from what you have.

I see now that if the last names are the same you want to arrange them by first name. The concept of your sort function is good, but you are going about it the wrong way.

Do not work on the whole program at one time. Break it down into smaller pieces and when they work add more.

Hope that helps,

Andy

P.S. Changing the name of the topic does not elicit a better response.

May I add that you also don't tell us what the problem is so I'm not going to bother to also find the problem and solve it.
