RE: [Dev-C++] Why thisC example don't presents the correct result ?

I'm not sure exactly what you are trying to do.  Bounds checking in c =
could be done this way but only if you actually initialized all of your =
subscripts.  Since v[2] is never initialized you are getting whatever =
value is stored in this memory space which could be anything.  Character =
arrays used for strings are the only thing I would know of that would =
store a null in the last position, but even this would only be true if =
you initialized the c string with an actual string instead of =
characters.
=20
char v[3] =3D "AB"; will result in 'A', 'B' and '\0'
char v[3] =3D {'A', 'B'} will result in the 3rd position being =
uninitialized
=20
In short there isn't bounds checking in C and you can't assume that a =
value exists unless you place it in the array yourself. It would be =
safest to keep the size of the array in something like a constant and =
use that for looping through your array.

Hi all,=20
in others compilers this is the result :=20

10=20
200=20

of this program :=20
#include=20
main  <http://pcp.clix.pt/images/canais/webmail2/smile/kiss.gif>=20
{=20
int v[3],i;=20
v[0]=3D10;=20
v[1]=3D200;=20
i=3D0;=20
while(v[i]!=3D'\0')=20
{=20
printf("%d\n",v[i]);=20
i++;=20
}=20
}=20

in dev-c++compiler i have the this result :=20
10=20
200=20
2293664=20
4198592=20
4210688=20
4210692=20
2293664=20
4198757=20
1=20
4138088=20
4139640=20
4198553=20


Why ?????=20

Thanks.=20
