Hi yet again! This time it’s a madlib. the code is provided below and my problem right now is when I try to compile from Dev-C++ I get… ‘[Linker error] undefined reference to ‘__cpu_features_init’’ and on the next error output line it says ‘Id returned 1 exit status.’ What am I doing wrong this time? thank you…(sorry about all the crap, I don’t know what that is)

Very difficult to read with all the color code there.
Maybe you could provide a file?

I’ll upload a file just as soon as I get home, I’m using a library computer at the moment. thank you for a response

Sorry, I guess I don’t know how to upload a *.c file, the attatchment thing only allows pics, I’ll try with just the text again…

You’ll probably need to include <string.h> and use strcpy() in your switch statements.


/* strcpy() prototype */
char *strcpy(destinationString, sourceString);

/* strcpy() returns a pointer to the destination string
 *
 * example:
 */
strcpy( rthing, "dog");

It worked for me after including stdlib for the srand function

include <stdlib.h>

also try adding a pause at the end so it stays on the screen
system(“pause”);

7

Don’t you need a default switch case?

8

Actually, the default case is optional, as are the break statements (although, leaving out breaks in a case will cause it to plow through each case until it does find a break or the end of the block).

Another thing: I suggested above to use strcpy() since the code uses character arrays, but I normally use char pointers in a case like this:


/* code snippet */
int number;
char *zeroOrNot;

number = 1;

if(number)
  zeroOrNot = "Not Zero
";
else
  zeroOrNot = "Zero
";

printf(zeroOrNot);

I’m sorry, I don’t really understand pointers and more advanced stuff

10

Then it’s about time you learn it…
The statement ’ r_thing==“monster”; ’ does exactly nothing, and i bet your compiler even told you…you probably meant ’ r_thing=“monster”; ’

Btw. don’t forget to free strings when you use strcpy. Welcome to the world of memory leaks…

11

Good catch! I never noticed the “==” in there. That’s been the problem all along. Of course, now when he changes it he’ll find he needs to use strcpy() or it won’t compile.
