error C2446: '==' : no conversion from 'int' to 'char *'

[QuantNeeds]

Help I am having the following error:
error C2446: '==' : no conversion from 'int' to 'char *'

When I tried the following it ignores my counter and I am not sure why. This is a serious problem because it creates and infinite loop that keeps printing.

if(char(seating[openSeat + potential]) == '#')
      counter2++;

My code is the following:

void Tickets::displayOptions()
{
cout << "The following blocks are available: " << endl;

for(int openRow = 1; openRow < row; openRow++)
{
cout << "row " << openRow << ": ";
for(int openSeat = 1; openSeat < seat; openSeat++)
{
      int neededSeatsOpen = (seat-1) - (openSeat - 1);
      if(neededSeatsOpen >= qty)
      {
	int counter2 = 0;				
	for(int potential = qty - 1; potential >= 0; potential--)
	{
                     if(char(seating[openSeat + potential]) == '#')
	     {
		counter2++;
	      }
	}
	      if(counter2 = qty)
	     {
		for(int available = 0; available <= qty - 1; available++)
		{
	                	cout << seating[openSeat + available] << " ";
		}
                     }
       } // end if
} // nested end for
}// end for
} // end function display Options

Why the cast to type char regarding the variable seating[]? Or in otherwords, seating is an array of what type?

seating is an array of type char

[Lerner]

If seating is an array of char, then there is no need to cast seating[] to type char because seating [] is a char.

I don't see where you are trying to equate an int with a char pointer or char array, though I've never tried to cast a variable to it's own type to know what would happen. If dropping the cast to type char doesn't work then trying to isolate the error some other way will be needed for me to be of help.

I do know that this isn't doing what you want:

if(counter2 = qty)

That should be the equal operator, not the asssignment operator.

[Duoas]

The compiler believes that seating is an integer. The OP placed the cast there to try to get rid of the error message.

Can we see the class definition where seating is declared? Is there anything else between the class and the variable? Did you #include the header in the .cpp file?

Hope this helps.

thank you - I did not even catch that.

Sure - below is my entire code. Where I actually call the displayOptions() function I commented out so I could work with my other functions.
Basically if I do not use the cast char to convert it and only use this:

if(seating[openSeat + potential] == '#')
{
     counter2++;
}

I get the following error:
.cpp(259) : error C2446: '==' : no conversion from 'int' to 'char *'
.cpp(259) : error C2040: '==' : 'char [31]' differs in levels of indirection from 'int'

Hence I left my code as with the char but there is still something strange going on in that displayOptions() function that produces garbage and that is why I cannot use my function.

Please help. My code is the following:

	int theaterAvailability;

};

Ah, it is because seating is declared as a 2D array, but you are only indexing one dimension. Hence the error.

Did you mean to treat seating as a 1D array in your function? I'm not sure how you are trying to index the seating array in your function...

If I am reading it right (from just a quick glance over your code) it should be: if(seating[openRow][openSeat + potential] == '#') Hope this helps.

Thanks@! I hate when I spend so much time trying to fix code and it turns out to be something that should have been so obvious.

Thanks again :)

I know what you mean. When I was first learning C I spent three or four days once trying to figure out an error -- which turned out to be a missing } in an #included file...

An extra pair of eyes if always useful for these kinds of things.
