Question

std::cout vs cout

Asked by: Klogg96

This is weird:

A description of the problem:
The code here (most likely full of errors / oversights) doesnt seem to operate in the proper timeline.  The std::cout line near the bottom appears to execute prior to the cout commands.  If all cout comands are changed to std::cout the display in the proper order.  Third, I thought the use of namespace std would make all the cout commands change to the equivlent of std:cout bout it doesnt.  Fourth, when namespace std is included the ifstream command doesnt work.  Fifth, I am trying to read space delimited text files that have $XXX as identifiers for keywords (here XXX are the first three letters of the key word) followed by space delimited numbers on the following lines.  Any recommendations?

I know that this is an overwhelming amount of questions all rolled into one request but I am so lost ...

I have very little experience with C or C++ but have much experience with VB (embedded in Excel).  This is also my first experience with the MS Vual C++ environment.  The code below is a command line code that eventually I would like to include in a desktop application.  (This is not school related, simply a personal project)

ANY INFORMATION you can provide is expreamly appriciated!!  Feel free to email too, junkdron@socal.rr.com

#include <stdio.h>
#include <fstream.h>
#include <string>
#include <iostream>

//using namespace std ;

void main()
{
      char FromFile[15];
      std::string FromFile2;

      ifstream InputFile;
      InputFile.open("520HW2.inp");

//      istream& get( char* FromFile, int streamsize=4);

      FromFile[0] = 's';
      cout << "the read value is: \n" << FromFile << "\n";

      strcpy ( FromFile, "hello world strcopy" );
      cout << "the read value is: \n" << FromFile << "\n";

      FromFile2 = "hello world strings";
      std::cout << "the read value is: \n" << FromFile2 << "\n";
}

It appears that you are mixing old headers with new headers :

#include <stdio.h>
#include <fstream.h>    // old non-standard header
#include <string>
#include <iostream>     // standard header

change the fstream include to :

#include <fstream>


It also seems like the fstream.h header includes <iostream.h>, so
the "cout" is from <iostream.h> and the "std::cout" is from <iostream>
