I just watched the C lecture the other day, and tried making my first program in the online developer environment (CS50 IDE). Just like the lecture, I am trying to use the compiler command to turn my "source code" (titled: feelings) into "machine code." When I type "clang feelings.c", it says that it does not exist. When I type "clang feelings", it says "clang-7: error: linker command failed with exit code 1 (use -v to see invocation."
