 char tmpchar1;
 char tmpchar2;
 counter=0;
    while (! inputfile.eof() )

    {

      counter++;

      tmpchar1=getchar(inputfile);

"Program06.cpp", line 61: Error: Too many arguments in call to "std::getchar()".
"Program06.cpp", line 61: Warning: A non-POD object of type "std::ifstream " passed as a variable argument to function "std::getchar()".

Updating my issue:
Heres the code:


inputfile.open(source.c_str());                        //Opens file

 char tmpC;
 char tmpchar1;
 char tmpchar2;
 counter=0;
    while (! inputfile.eof() )

    {

      counter++;

      getline (inputfile,line);
      tmpchar1=line[counter];
      if (tmpchar1 == '/')                                    //checks if file is open

      {
     
cout << "found a comment";
      }

    }

    inputfile.close();


Here is the error:

sr4 $ CC -o Program06 Program06.cpp
"Program06.cpp", line 64: Error: "}" expected instead of "tmpchar1".
1 Error(s) detected.
i dont know why its giving you that error (in the second post) but it looks like getline() doesnt have that overload.

getline() works like this:

istream& getline (char* s, streamsize n );

where s is your character array, and n is the maximum number of characters to read.

also, getline() is a function of the class istream, so you need to do it something like this

char line[256];
inputfile.getline(line, 256);

also, taking a look at your code, it looks like your logic says you want to take the Nth character in the Nth line, meaning if your text file was

run
bob
run

tempchr1 would be

'r' in the first iteration
'o' in the second
'n' in the third

if thats what you want, thats cool, just looked kinda fishy

fool around with what i said, let me know if you have any more questions

Im trying to read a file char by char and count how many time "/*" or "//" show up.
What do you think?
