Hello all,

I am working on a program that takes input from a file, removes extra white spaces and outputs the edited text to another file.

So far my program deletes 1 whitespace whether the whitespace should be deleted or not.

I have read about peek() and putback(). I am pretty sure I need to implement these two functions but quite frankly I am not sure how to go about doing this.

I don't want anyone to just give me the answer I would really appreciate it if someone gave me a hint as to where my logic went south or my structure or enlighten me about some predefined function you think I may not be aware of.

Any help is appreciated. Thank you.

using namespace std;
void check_blank(ifstream& instream, ofstream& outstream);
int number = 0; //keeps track of how many spaces have been deleted

int main() 
{
  ifstream instream;
  ofstream outstream;
  bool     t;
  
  instream.open("hw4pr6input.txt");         //Open file: text to be edited
  if(!instream.fail())                      //Make sure file opened successfully
  {
  cout << "test from open";
     //Call function that finds blanks and edits
  }
  else
  {
    cout << "File failed to open (1st)";
    exit(1);
  }
  
  outstream.open("hw4pr6output.txt");       //Open file: edited text will go
  if(!outstream.fail())                     //Check if open failed
  {
   t = true;   
   check_blank(instream, outstream);              //Call function to input edited text into file
