Extracted text: 2. hello world Write a hello.c file that contains two functions. The function sayHello should take a single string (char *) parameter and write the message "hello" followed by the value passed in. So if you call sayHello("world"), the result should print hello world You should use printf to do the printing. The function main should call sayHello("world") as its only work. Make sure your hello can be compiled all the way and correctly runs. Generate hello.s and comment it as above. Note that the compiler can do some different things for main.
