cout problem

[Draahl]

im extremely new to c++ programming, started today actually and ive come across a small problem.

I get an error when trying to do a simple sizeof program using cout.

#include <limits.h>

int main(void)

{
    int n_int = INT_MAX;
    short n_short = SHRT_MAX;
    long n_long = LONG_MAX;
    
    cout << "int är " << sizeof(int) << " bytes.\n";
    cout << "short är " << sizeof (short) << " bytes.\n";
    cout << "long är " << sizeof (long) << " bytes.\n";
    
    cout << "Maxvärden:\n";
    cout << "int: " << n_int << "\n";
    cout << "short: " << n_short << "\n";
    cout << "long: " << n_long << "\n";
    
    cout << "Minsta intvärde = " << INT_MIN << "\n";
    return 0;
}

Have i done anything wrong? And if so, what do i need to do to fix it?
Im using Dev C++ 4.9.9.2.

I think that you haven't included the right header #include<iostream> or #include<iostream.h> for the cout I/O flux. Try to include those headers and see if it works!

I was able to compile it this way in MS visual C++ 2008 Express. Not sure about Dev C++. Try leaving out the

#include "stdafx.h"

if it doesn't want to compile.

// Sizeof.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include <limits.h>

int main(void)
{
    int n_int = INT_MAX;
    short n_short = SHRT_MAX;
    long n_long = LONG_MAX;

    std::cout << "int är " << sizeof(n_int) << " bytes.\n";
    std::cout << "short är " << sizeof (n_short) << " bytes.\n";
    std::cout << "long är " << sizeof (n_long) << " bytes.\n\n";
    
    std::cout << "Maxvärden:\n";
    std::cout << "int: " << n_int << "\n";
    std::cout << "short: " << n_short << "\n";
    std::cout << "long: " << n_long << "\n\n";
    
    std::cout << "Minsta intvärde = " << INT_MIN << "\n";
    std::cout << "Maxsta intvärde = " << INT_MAX << "\n";  // Not sure of wording. Just showing INT_MAX
    return 0;
}

You need to add iostream not limits.h. Further you write "using namespace::std;" (without quotes) after including the specified directive. This will solve your problems.

I love you guys, thanks! the iostream.h worked :)
