Help with variables (newbee)

I am trying to use conditinal statements to define text in variables.

ex

if (x>0)
{
somevariable="This is summer";
}

i later want to be able to recall the variable.

such as

printf("%s",somevariable);

however, my output reads foreign characters or random lines in the program.

any help is greatly appreciated.

How about posting your actual code, and not some non-complete example? My guess is you forgot your null.

Quzah.

You want to declare your #defines in global space, outside of main(). Also on the line

Code:

---

while (rerun=1) /* user selection handling  */

---

you typo'd and forgot the second =. To fix your printf() statment switch %c to %s for curname.

[edit]umm...I saw code, I replied, and I dont see code anymore :confused: :D . I dont know what just happened, and if a mod wants to delete this post, go ahead.[/edit]

was missing an asterisk in the declaration. thanks....

#define's dont have scope

True, but it's still a good idea to always have them very close to the top of the file. That's where they most often are, and since you gain nothing by having them elsewhere (due to the scopelessness), you might as well have them where people would look for them first.

Well, saying they have no scope isn't quite correct. They can't be used anywhere in the file above where they're defined. For example:

Code:

---

int foo = FOO;
#define FOO 1

---

...won't work.

Scope could be defined as between the #define and #undef directives or the end of the file. I've used that sort of thing before too:

Code:

---

ATTR atr_list[] =
{
#define DOATR(a, b, c, d) { a, d, NULL, c, NULL, NULL },
#include "attrlist.h"
#undef DOATR
  { NULL, 0, NULL, 0, NULL, NULL }
};
#define DOATR(a, b, c, d) ATTR *b;
#include "attrlist.h"
#undef DOATR

---

where attrlist.h is a lot of lines like:

Code:

---

DOATR("Password",          A_PASSWORD,        SDARK|NOMOD,        5)
DOATR("Desc",              A_DESC,            INH|OSEE,          6)

---

So anyway, just thought I'd point that out :)
