#C

Most of this code comes from an answer to Find the beginning of the first word that is a palindrom [sic] posted by BLUEPIXY, which outputs the word mom. At lines 21 and 22, the hello is printed by a code snippet at the end of an answer to printf(“%%%s”,“hello”) by user142019 (who fortunately added a semicolon at the end), and the space between the words comes from an answer to How to print space with padding in c by M Oehm.

###Output:

%hello        mom

I wasn't able to eliminate the extra spaces or the percent character, unfortunately :(
