Can you put breaks in a string literal?

This is a constant I am using, it is split like this because I did not want to have to scroll my editor 

const string PROGRAM_DESCRIPTION = "Program will calculate the amount "
"accumulated every month you save, until you reach your goal.";

int main() 
{
    cout << PROGRAM_DESCRIPTION;
    return 0;
}

Currently prints out in command prompt as

Program will calculate the amount accumulated every month you save,until you re
ach your goal.

When this prints out I would like it to print on two separate lines like below...

Program will calculate the amount accumulated every month you save,
until you reach your goal.

I do not know where to put break statements in a string so I can get it to print out correctly.

Well answers are good, however my offer is to use \r\n for new line. Read here some more, these two symbols should always work (unless you are using Atari 8-bit OS).

And some more explanation.

  • \n - Line Feed. This should move printing pointer one line lower, but it may or may not set printing pointer to beginning o line.

  • \r - Carriage Return. This sets line pointer at the beginning o line, and may or may not change line.

  • \r\n - CR LF. Moves printing pointer to next line and sets it at the beginning of line.

Just insert a line break "\n" in the position you want in your const string, as you would do in a normal literal string:

const string PROGRAM_DESCRIPTION = "Program will calculate the amount\naccumulated every month you save, until you reach your goal.";

cout << PROGRAM_DESCRIPTION;

Simple. Just the same way as you should me used to in using a literal string:

cout << "Program will calculate the amount\naccumulated every month you save, until you reach your goal.";

Right?

In C++11, you can use a raw string literal

const char* stuff =
R"foo(this string
is for real)foo";
std::cout << stuff;

outputs:

this string
is for real

(I put this answer here for pedantic reasons, use \n)

You can use \n at the end of the first part of the literal for that, like this:

const string PROGRAM_DESCRIPTION = "Program will calculate the amount\n"
"accumulated every month you save, until you reach your goal."; //   ^^

You do not have to split the literal into parts if you do not wish to do so for readability:

const string PROGRAM_DESCRIPTION = "Program will calculate the amount accumulated every month you save,\nuntil you reach your goal.";

Add \n in the string where you want the line to break.

Just insert a \n character to force a new line 

const string PROGRAM_DESCRIPTION = "Program will calculate the amount "
"accumulated every month you save, \nuntil you reach your goal.";
