Adding a comment

[Samuel Onate]

Can someone help? Please check this code. After the do while loop, I want to put a comment. how can this be done? What I have here does not work.

#include <iostream>

Thanks in advance. Hoping someone can help me.

Sorry, but I don't read long code that is not in code brackets. Use [ code ] and [/ code] around your code if you want us to read it.

As for comments there are two things that I suspect you mean:
first: Just put // in front of whatever you want commented.
second: just put cout << something; wherever you like in your code.

Oh ok...thanks for the tip my friend, you guys arent just being jerks. : )

Ah ha, I see your problem now:

You can't put {} inside of a while loop condition.

while (something != {...}) is invalid. When I try to compile I get:

1>Snippets.cpp(31): error C2143: syntax error : missing ')' before '{'

I think you'll have to do this inside of the while loop instead:

const char kcaaInitial[4][4] = {
{'1', '2', '3', '4'},
{'5', '6', '7', '8'},
{'9', 'A', 'B', 'C'},
{'D', 'E', 'F', ' '}};

do {
  // Your stuff
  // ...

  bool match = true;
  for (int i = 0; i < 4; i++)
    for (int j = 0; j < 4; j++)
      if (caaBoard[i][j] != kCaaInitial[i][j])
        match = false;
} while (!match);

If you like you can make this a function:

bool match(char array1[4][], char array2[4][])
{
  for (int i = 0; i < 4; i++)
    for (int j = 0; j < 4; j++)
      if (array1[i][j] != array2[i][j])
        return false;
  return true;
}

Then your while loop condition would look like this:

const char kcaaInitial[4][4] = {
{'1', '2', '3', '4'},
{'5', '6', '7', '8'},
{'9', 'A', 'B', 'C'},
{'D', 'E', 'F', ' '}};

do {
  // Your stuff
  // ...
} while (!match(caaBoard, kCaaInitial));
