help guys please!! =((

Answer 1

helpers.c does not contain a main function, so it cannot be compiled into an executable. Its code is used in find.c, make find instead of helpers, using either

make find

or

clang -ggdb3 -O0 -std=c99 -Wall -Werror -o find find.c helpers.c -lcs50 -lm

and use calls to find to debug helpers.c.
