Invalid suffix literal error!

Question

#include <iostream>
using namespace std;

int main()
{
cout << "Hello world! \"<< "I love programming!";
return 0;
}

The above code compilation throws an error - "invalid suffix literal"

what does that indicate?

Answer 1

because you use \" and that means that " will be considered as " character and not enclosing string character so you didn't close string then

Answer 2

\ "

i.e. A space between \ and " escapes the whitespace and not the ". Hence, there is no error.

Answer 3

However,

"Hello World! \ "

doesn't throw an error.
\ followed by a space and then " works fine. Error occurs only when there is no space.

Answer 4

thanks guys!
