6, enter ./A and then enter, you can see the execution results of the program A.C: print out Hello world! at the terminal This sentence.

macbook-pro-2: ~ mac$./Ahelloworld! MacBook-pro-2: ~ mac$

Note: The code for step 5th above is actually made up of four steps:

(1) Preprocessing: Use-e to generate. I files:

GCC-E A.c-o A.I

(2) Assembly: use-S to generate. s files:

Gcc-s A.i-o A.S

(3) Compile: Generate. o Files using-c:

Gcc-c A.s-o A.O

(4) Connection: Use-o to generate the executable file:

GCC A.o-o A
