Starting with Programming 5 Module, running C programs, the compilation and execution of the code is different. Refer to module 5 “Running C Programs”. Unlike Python, you must first compile the code, then execute it: “gcc -o hello hello.c” where “gcc” calls the C compiler, “-o” defines the output of the compilation to be “hello” and “hello.c” is the file/code to be compiled. After compiling and creating the file named “hello”, to execute the program, type “./hello”. The “./” define the location of the file “hello”. “./” defines the present working directory.
