This program is a simple bejewel game... i need to enter the matrix pos[alpabet][number]...eg(a1 or b7)
so if i error input for example:
11 (cout error) this can work
aa (cout error) but this will infinite loop...

please help me... besides some one can tell me what can i do with c++???? i use it to make game like this but it look boring... so what can i use c++ in more advance???

>>what can i do with c++????
You can use vector instead of arrays.

line 5: should be <string> to get std::string class

line 24: use int main()

line 129: you need to make that function return a value if the loop never finds what it is looking for.

Spell out the words in the instructions -- don't use chatroom speak, which make your program look childish.

But the infinite loop error still haven't solve... I will learn better english and re-write it.. and i learning c++ so i'm not very concentrate on the english... sorry~~~~~~~~~~~~~~~~~~

line 44: you can't enter two values without spaces like that. Here is a suggested alternate way to do that: Get the 2 characters as a string then split them apart. See this thread for explaination of the cin.ignore() line

#include <limits>
...
<snip>
      x_char = 0;
      y = 0;
      string input;
      cin >> input;
      cin.ignore ( std::numeric_limits<std::streamsize>::max(), cin.widen ( '\n' ) );
      if( input.length() == 2)
      {
        x_char = input[0];
        if(!isdigit(input[1]) )
        {
            cout << "Error -- second character must be a digit 1-9\n";
            cin.get();
        }
        else
            y = input[1] - '0';
      }

help me check a simple game's error ^^
