There is a space in the directory name "Programming 1", so that with
$ /Users/dawasherpa1/Desktop/Programming 1/Strings/bin/Debug/Strings
the shell tries to execute "/Users/dawasherpa1/Desktop/Programming" with the argument "1/Strings/bin/Debug/Strings". You have to enclose the entire path in quotation marks
$ "/Users/dawasherpa1/Desktop/Programming 1/Strings/bin/Debug/Strings"
or escape the space with a backslash
$ /Users/dawasherpa1/Desktop/Programming\ 1/Strings/bin/Debug/Strings
to execute your program.
