hi im in a trouble with c++ i made a project with c but icant convert c
++ here is the code with c

[ 8< --- massive amounts of code snipped ]

Comment out parts of the program until it compiles cleanly. When it
compiles successfully for the first time, you know that the last part
you commented out has an error as far as your C++ compiler is
concerned. Fix it.

Un-comment a little more. Repeat the fixing process as necessary.

Of course, using C-style code in a C++ program just isn't a good idea,
anyway. malloc and company are used very little indeed in C++.
std::vector<> should be used for dynamically sized arrays.

You should also look at sprinkling in some polymorphism too, perhaps,
if you're up to it, rather than littering the code with switch
statements.

There seems to be a couple of things wrong with this program
1. There seems to be a few misplaced brackets.
2. In main you are trying to access MyArray directly. Its a private
datamember of clas proje. So you need to create a method within proje
to return you this structure.
3. Menu is a member function of proje, you cannot access it directly.
You need to do something like
proje p;
p.menu();
4. The do loop should look like
do
{
system("CLS");
secim=p.menu();
p.menuIslemleri(secim);
}while(secim!=7);
5. use cin and cout instead of scanf and printf

Once you are done with these changes maybe we can help you further.
