Question

Working on outputting either a real number or integer number
i’m reading in a number character by character from a file. It will read an integer and push it into integerQueue up until it reaches a ‘.’, then it will switch to inputting it into a realQueue.

Then when i print, it needs to print out i.e. Real: 123.4343

But right now the output is Real: 123. Integer 4343

Somehow my while loop or my if statement isn’t doing its job. I just can’t find my error

question is, How do I fix my output so that it prints out 123.4343

    //if the realQueue is empty, then we just read in an integer, currentState must be 1, in order to print integer
            if(realQueue.empty() || currentState == '1')//implementation of the FSM
            {
                    writeFile <<"Integer:       ";
                    while(!integerQueue.empty())
                    {
                    writeFile <<integerQueue.front();
                    integerQueue.pop();
                    }
            }
            //since the realQueue has values in it, then it must bea real Number
            else
            {
                //currentState = '2';
                // currentState must be == '2', since wwe have a real number to print

                    writeFile<<"Real:           ";
                        //currentState has to be in real mode for it to print out to file
                        while(!integerQueue.empty() && currentState == '2')
                        {
                        writeFile <<integerQueue.front();
                        integerQueue.pop();
                        }
                        // currentState has to be in real mode for it to print out to file
                        while(!realQueue.empty() && currentState == '2')
                        {
                        writeFile <<realQueue.front();
                        realQueue.pop();
                        }

            }

Try comminting this loop out and see what happens.

while(!integerQueue.empty() && currentState == '2') 
{ 
  writeFile <<integerQueue.front(); 
  integerQueue.pop(); 
}
