Am I doing my C codes right? They are failing to compile

[php111]

I am not sure how to write the code tags here. I am going to try to write them with tags. If I am doing them wrong, will someone please edit my post and fix it? Thank you.



I was trying to compile code and it was failing to compile.

Here is the code from the C Primer Plus 5th Edition book.

code:

#include <stdio.h> int main(void)                /* a simple program             */ {     int num;                  /* define a variable called num */     num = 1;                  /* assign a value to num        */     printf("I am a simple "); /* use the printf() function    */     printf("computer.\n");     printf("My favorite number is %d because it is first.\n",num);     return 0; }

Here is my code:

code:

#include <stdio.h> int main(void) /* a simple program */ {         int num; /* define a variable called num */                 num=1; /* assign a value to num */                 printf("I am a simple "); /* use the printf function */                 printf("computer. \n");                 printf("My favorite number is %d because it is first. \n",num);                 return0; }

Here is the error I get.

Wow. I seen I done the code tags right. Lol.

[Clayton]

code:

return0;

Should be:

code:

return 0;

Note the space.

[php111]

Clayton,

I did put a space this time and it's still failing.

code:

#include <stdio.h> int main(void) /* a simple program */ {         int num; /* define a variable called num */                 num=1; /* assign a value to num */                 printf("I am a simple "); /* use the printf function */                 printf("computer. \n");                 printf("My favorite number is %d because it is first. \n",num);                                 return 0; }

I don't think you installed your compiler properly. Either that or try replacing

code:

#include <stdio.h>

with

code:

#include "stdio.h"

Tried it and failed.

To make sure I had downloaded the right one.

I got the one in the Orange color.

Did you try building a Windowed app instead of a Console(Command Line) app?

Do not use Microsoft Visual Studio. It expects you to use precompiled headers (most useless thing ever in my experience), when you don't even know what a header is.

Use a text editor and a command-line compiler, you will learn things a lot quicker and easier.

[php111]

Alright, everyone is going with command line. I got Ch again.

The code up in my original, how do I write it and compile it using Ch?

[btiffin]

Type it in to a text file

From Ch prompt, this is how I plowed my way through ... the beauty of an interactive system ... do something stupid, it'll let you fix it.

code:

lang/ch6/src> ./sample.c lang/ch6/src/sample.c: Permission denied lang/ch6/src> sample.c ERROR: variable 'sample.c' not defined ERROR: command 'sample.c' not found lang/ch6/src> chmod +x sample.c lang/ch6/src> which chmod /bin/chmod lang/ch6/src> ./sample.c I am a simple computer. My favorite number is 1 because it is first. lang/ch6/src>

So basically you execute the code by naming the source in Ch shell. I used ./ (dot slash being a POSIX thingy for; execute the program from this directory and don't bother looking through the PATH) and chmod +x to get permissions. Early Unix and C coders didn't use many vowels. chmod reads as Change Permission and or Attribute Modes. chmod is NOT a normal Windows command, but Ch is a fairly complete shell space. chmod +x tells the machine to allow execute permissions under a POSIX system. Get used to POSIX. POSIX good.

And when I say POSIX I mean Unix and GNU/Linux and the Ch shell, in spirit of standard if not technically "compliant". And realize ... Ch interprets the code, not really learning some of the ins and outs of compiling code.

Don't spend too much time on Ch, Learning C is worthless if you don't learn to use standard tools. GCC, by way of being both very good and very free is exceedingly popular.

It also scales well. Compiling a very simply program with gcc is exceedingly simple.

code:

$ cat simple.c #include <stdio.h> int main() {     printf("Listen to the duck. The duck is good.\n");     return 0; } $ gcc -o simple simple.c $ ./simple Listen to the duck.  The duck is good. $

What? I am sorry but I do not understand. I do not know how to fix it and even if it was the right way, I still don't know how to write it in a Ch editor.
