Thread: error help

hi all, I'm a beginner - got a book about C++, there's a example of a program but when I type it, I get an error everywhere where "cout" is here's the code maybe you'll know what's wrong (all it says in the message is: `cout'

Code:

// booltest - compare variables input from the
// keyboard and store the results off
//into a logical variable
#include <cstdio>
#include <cstdlib>
#include <iostream>

int main(int nNumberofArgs, char* pszArgs[])
{
// set output formal for bool variables
//to true and false instead
//of 1 and 0
cout.setf(cout.boolalpha); // HERE

//initialize two arguments
int nArg1;
cout << "Input value 1: "; // THEN HERE etc
cin >> nArg1;

int nArg2;
cout << "Input value 2: ";
cin >> nArg2;

bool b;
b = nArg1 == nArg2;

cout << "The statement, " << nArg1
     << " equals "        << nArg2
     << " is "            << b
     << endl;
     
      //wait until the user is ready before terminating the program
      system("PAUSE");
      return 0; 
}

...I'm using Dev-C++ (came with the booK) if there's any other c++ editors that you'll recommend please let me know

including the error message in ur post would be helpful

change cout to std::cout and cin to std::cin

std::endl

std::cout.setf(cout.boolalpha); // HERE

Your problem is that everything in standard libraries is in a std namespace. To use the names you'll need to prefix every standard library name with "std::" (or use the "using" directive).

Think, why do the issues get fixed when you prefix std:: and why do you get errors in places where you don't...
