Can anyone tell me why I'm getting build errors on the actual function heading and the line under it (**) saying "type bool is unexpected" and that I'm missing a ; before {? I've looked and can't find anything.

Also, I get this error but there is no line 80 and all my braces match up (I think):
pa2-q1.cpp(80) : fatal error C1075: end of file found before the left brace '{' at '.\pa2-q1.cpp(17)' was matched


Any help is appreciated! :confused:

Any help is appreciated! :confused:

bool Bsearch (int , int , int , int, int&);

bool Bsearch (int chart[], int find, int start, int end, int& tms)

remove the & after the last int in the bool Bsearh fuction

else
{
//bool found=0
if (Bsearch(chart[MAX_ITEMS],find,start,end,tms))
cout<<"Your number was found in the list after "<<tms<<" passes."<<endl;
else
cout<<"Your number was not found in the list after "<<tms<<" passes."<<endl;

cout<<"Search for another number? Enter 1 for Yes or 0 for No: ";
cin>>cont;
} while (cont);

_getch();
return 0;
}

You are missing an ending bracket for the first else. The one right after while belongs to the do/while loop.

remove the & after the last int in the bool Bsearh fuction

Aia, I tried that but it didn't help. :sad:

here is the exact text of the bool and brace errors also:

.\pa2-q1.cpp(59) : error C2062: type 'bool' unexpected
.\pa2-q1.cpp(60) : error C2143: syntax error : missing ';' before '{'

>remove the & after the last int in the bool Bsearh fuction
Why?

2 things I noticed about your code:

  • Your function implementation differs from the prototype in the sense that the prototype doesn't accept an int array for the first parameter. Change it to something like this:
    bool Bsearch (int[], int , int , int, int&);
  • This is NOT how you pass an array: chart[MAX_ITEMS] . Just omit the [] and use chart .

Thank you...thank you!!! I don't know why I can't seem to get it straight on how to pass/declare arrays in a function.


.\pa2-q1.cpp(59) : error C2062: type 'bool' unexpected
.\pa2-q1.cpp(60) : error C2143: syntax error : missing ';' before '{'

The first line I think is because in the prototype you have the first
parameter as an int and in the actual function is a int array.

I always copy my function and use it as a prototype, just adding the ; and the end.

The second error I can not see any missing ; any where. Are you sure that your posted copy is the same you are compiling. In my compiler after fixing the little mispells I don't have those errors.
I have other errors, but will get there... :lol:


What are you trying to do passing as a parameter int& tms?

>What are you trying to do passint as a parameter int& tms?
It's a counter. If it wasn't passed as a reference, it wouldn't update because the variable would be a copy of the original.

It's a counter. If it wasn't passed as a reference, it wouldn't update because the variable would be a copy of the original.

Mister Joeprogrammer,
Am I correct, then, in assuming that this way of reference in a function is something different for C++ than for C? I know you can not do it in C, but my C++ is very limited.

Yes. It's more convenient than a pointer, and much safer, because you don't have to worry about accidentally mispointing it.

Thank you. Much appreciated.

Oh and btw, just call him Joey, he really likes it. :D
