How can I limit my printf statement to 80 characters per line in the code in c++?

My professor requests that my code does not exceed 80 characters per line, but I have some printf statements that exceed this limit. Is there a way to break this statement into two or more lines without changing the output?

Example by request:

printf("\n%-20s %-4d %-20s %-4d %-20s %-4d\n%-20s %-4d %-20s %-4d%-20s %-4d\n%-20s %-4d %-20s %-4d %-20s %-4d\n%-20s %-4d %-20s %-4d %-20s %-4d\n%-20s %-4d %-20s %-4d\n", "1 - Ones", ones, "2 - Twos", twos, "3 - Threes", threes, "4 - Fours", fours, "5 - Fives", fives, "6 - Sixes", sixes, "7 - Three of a Kind", threeOfAKind, "8 - Four of a Kind", fourOfAKind, "9 - Full House", fullHouse, "10 - Small Straight", smallStraight, "11 - Large Straight", largeStraight, "12 - Yahtzee", yahtzee, "13 - Chance", chance, "Total Score: ", score);

In C++, you can break literal strings like this:

printf("This is a very long line. It has two sentences.\n");

into

printf("This is a very long line. "
       "It has two sentences.\n");

Any double-quoted strings that are separated by only whitespace, are coalesced into one string by the compiler before parsing. The resulting string does not contain any extra characters except what is between each pair of double quotes (so, no embedded newline).

For the example included in your post, I might do the following:

printf("\n%-20s %-4d %-20s %-4d %-20s %-4d\n"
       "%-20s %-4d %-20s %-4d%-20s %-4d\n"
       "%-20s %-4d %-20s %-4d %-20s %-4d\n"
       "%-20s %-4d %-20s %-4d %-20s %-4d\n"
       "%-20s %-4d %-20s %-4d\n",
       "1 - Ones", ones, "2 - Twos", twos, "3 - Threes", threes,
       "4 - Fours", fours, "5 - Fives", fives, "6 - Sixes", sixes,
       "7 - Three of a Kind", threeOfAKind,
           "8 - Four of a Kind", fourOfAKind,
           "9 - Full House", fullHouse,
       "10 - Small Straight", smallStraight,
           "11 - Large Straight", largeStraight,
           "12 - Yahtzee", yahtzee,
       "13 - Chance", chance, "Total Score: ", score);
