int main()
{
using namespace std;
int x;
x = 5;
cout << x;

system("pause");
return 0;
}

You need to use pause command to pause the program in compilers like dev-c++
Hope it helps

For beginners, the move from

using namespace std;

to

std::

might be confusing.

Hence I suggest amending the example code accordingly, or leaving a note at the end of the tutorial highlighting the interchangeability feature of the two.

#include
using namespace std;

int main ()
{
cout <<"\nYour Code Here";
return 0;
}

Always remember Preprocessors go outside functions GL

#include

int main()
{

int x;
int y;
int d;
int f;
x = 5;
y = 5;
d = x + y;
f = d + d;

using namespace std;
cout << x + y << endl;
cout << f << endl;
return 0;
