macOS Complete Noob Question - learning C Hello World problems

Hi All,

I am completely new to programming and am currently learning C using X-Code and an ebook I downloaded from Spiderworks.com

It's a real beginner course and I am stumbling at the first block.

I have downloaded the Xcode program which opens and runs fine.

However when using the simple example programs which are designed to simply display text on the screen.

When I press build and go i get another window showing that "build was successful" but there is no output of the relevant text.

Here is the code (remember it's only C):

#include <stdio.h>

void SayHello( void );

int main (int argc, const char * argv[])
{
SayHello();
SayHello();
SayHello();

return 0;
}


void SayHello( void )
{
printf( "Hello, world!\n" );
}


Please can someone tell me where I'm going wrong?

Many thanks in advance.

Doesn't the "Build and Go" button compile it and then run it??

@TEG

I literally started the ebook this morning so what you say is still double dutch to me.

What is GCC??

@Cromulent

Thanks man. When I did that it showed all of the 50 thousand times i'd presses Build and Go.

Thanks to all for they help here. Lets see how I get on.
