For compiling a c program on your latest macOS just type the following in terminal after saving the file with a .c extension and on reaching the path where the file is saved :

cc yourfilename.c

Once you have checked all the errors after compilation (if any), type the following for executing the code :

./a.out

These commands are tested on macOS Mojave and are working perfectly fine, cheers coding!

1   First you need to install a GCC Compiler for mac  Google it and install it from the net    2  Remember the path where you are storing the C file  3  Go to Terminal and set the path  e g- if you have saved in a new folder ProgramC in Document folder     then type this in Terminal     cd Document     cd ProgramC   4  Now you can see that you are in folder where you have saved your C         program  let you saved your program as Hello c   5  Now Compile your program      make Hello      hello

First save your program as program c   Now you need the compiler  so you need to go to App Store and install Xcode which is Apple s compiler and development tools  How to find App Store  Do a  Spotlight Search  by typing   8984 Space and start typing App Store and hit Enter when it guesses correctly   App Store looks like this     Xcode looks like this on App Store     Then you need to install the command-line tools in Terminal  How to start Terminal  You need to do another  Spotlight Search   which means you type   8984 Space and start typing Terminal and hit Enter when it guesses Terminal   Now install the command-line tools like this   xcode-select --install   Then you can compile your code with by simply running gcc as in the next line without having to fire up the big  ugly software development GUI called Xcode   gcc -Wall -o program program c   Note  On newer versions of OS X  you would use clang instead of gcc  like this   clang program c -o program   Then you can run it with     program Hello  world      If your program is C    you ll probably want to use one of these commands   clang   -o program program cpp g   -std c  11 -o program program cpp g  -7 -std c  11 -o program program cpp

Answer is chmod 755 hello - it makes file executable    It is funny  so no-one answered it  I had same problem on MacOS  which is now solved  nano hello c make hello chmod 755 hello Then you run it by   hello clang --version Apple LLVM version 8 0 0  clang-800 0 42 1  Target  x86 64-apple-darwin15 6 0 nothing was installed  nano make  clang  chmod - all inside MacOS already

To do this    open terminal type in the terminal  nano   which is a text editor available for the terminal  when you do this  something like this would appear  here you can type in your C program type in control      x -  which means to exit  save the file by typing in y to save the file write the file name  e g  helloStack c  don t forget to add  c  when this appears  type in gcc helloStack c then   a out  this should give you your result

First make sure you correct your program    include  lt stdio h gt   int main void       printf  Hello  world  n      printf instead of pintf    return 0      Save the file as HelloWorld c and type in the terminal   gcc -o HelloWorld HelloWorld c   Afterwards just run the executable like this     HelloWorld   You should be seeing Hello World

A  C-program  is not supposed to be run  It is meant to be compiled into an  executable  program which then can be run from your terminal  You need a compiler for that   Oh  and the answer to your last question   Why    is that the file you are trying to execute doesn t have the executable rights set  which a compiler usually does automatically with the binary  which let s infer that you were trying to run the source code as a script  hence the hint at compiling
