Question

I need to make sure none of the lines in my code exceeds a a certain length.

Normally I separate lines where there’s a comma or another suitable break.

How can I separate this line into 2?

cout<<"Error:This is a really long error message that exceeds the maximum permitted length.\n";

If I just press enter somewhere in the middle it doesn’t work.

Answer 1

Two options:

cout << "Error:This is a really long "
 << "error message that exceeds "
 << "the maximum permitted length.\n";

Or:

cout << "Error:This is a really long "
    "error message that exceeds "
    "the maximum permitted length.\n";

The second one is more efficient.
