ok, heres the code, im sure uve all seen it b4...
#include <iostream>
int main()
{
std::cout << "Hello World!\n";
return 0;
}
When i run the program... nothing happens... isn't it supposed to display hello world to my screen???
(simplest program and i can't get it right :( )
It was just the window disppearing before i could even see it, thanks
either you have to use iostream.h or if you are using iostream
you have to write
using namespace std...
try removing theCode:#include <iostream>
int main()
{
cout << "Hello World!\n";
return 0;
}
std::
and use the code above
If you mean that the screen just closes after about a second, try taking some input before closing like this:
PHP Code:#include <iostream>
int main()
{
int i;
cout << "Hello World!\n";
cin>>i;
return 0;
}
When you #include <iostream>, you must either include the line "using namespace std;", the lines "using std::<object here>;", or prefix all standard object names with "std::". Here is the hello world program with all three options:
Code:#include <iostream>
using namespace std;
int main()
{
cout << "Hello World!\n";
return 0;
}
Code:#include <iostream>
using std::cout;
int main()
{
cout << "Hello World!\n";
return 0;
}
abdul is also correct. If the window simply flashes on and off screen again, try adding an input call like he did.Code:#include <iostream>
int main()
{
std::cout << "Hello World!\n";
return 0;
}
Z.
also, try flushing the buffer.
cout << "blah"; will stay in the buffer untill you flush the buffer into the screen. you have to use endl to flush the buffer or the function flush.
try:
Notice the endl to finish the line, it does more than just add a '\n' at the end. It also flushes the buffer.PHP Code:#include <iostream>
int main()
{
std::cout << "Hello World!" << endl;
return 0;
}
