Simply put, the file integer, the executable file, doesn't exist. Only the source code file integer.c exists. You need to make integer first, in order to compile the source code and produce the executable file integer. THEN, you can run it with the command ./integer.

you have to use "make filename" and then run the program with "./filename"
