Re: just a quick question here
Well, C++ can compile almost any C code, except for a few minors differences. Post the code and I'll see.

Re: just a quick question here
I know that c++ can compile most of c code, but i just need c++ code not c code heres the code:
C++ Syntax (Toggle Plain Text)
  1. #include <stdio.h>
  2. #include <string.h>
  3.  
  4. void addTeam(char[50], int);
  5. void calculateResult(int, int, int, int);
  6.  
  7. char newTeam[50];
  8. int menuChoice = 0;
  9. int numOfTeams = 0;
  10. int team1, team2, team1Score, team2Score;
  11.  
  12. typedef struct

Re: just a quick question here
Just look up printing and getting input using cout<< and cin>>. Also, use
C++ Syntax (Toggle Plain Text)
  1. #include <iostream>
  2. using namespace std;
That seems to be the only things you really need to change on first glance.
I'm sure William or someone else will correct me if I'm wrong.

  145.  
  146.  return 0;
  147. }
and these are the errors im gettin, look like it need a ";" or something like that???
In function `int main()':
33 elements of array `team teams[6]' have incomplete type In function `int main()':
33 storage size of `teams' isn't known
86 a function-definition is not allowed here before '{' token

Re: just a quick question here
You need to put return 0; at the end of main() and remove it from the end of the code. Remove the last 2 lines of the last code you posted.
