if-else

Code:

---

#include <stdio.h>
main()
{
char a,sk8;
printf("give password:");
scanf("%c",&a);
a=sk8;
if (a=sk8)
printf("well done\n");
else
printf("wrong password\n");
}

---

but can not understand else.anything i give to it,tells me well done.

if (a=sk8)
Use == for comparing, = for assignment.

You've written (essentially)
if ( (a=sk8) != '\0' )

Code:

---

#include <stdio.h>
main()
{
char a,sk8;
printf("give password:");
scanf("%c",&a);
a=sk8;
if (a==sk8)
printf("well done\n");
else
printf("wrong password\n");
}

---

ok.i change if but the same problem

What is sk8? If you dont initialize it, it'll be a garbage value.

a=sk8;
if (a==sk8)
Where between these two statements do you expect a to change to something different from sk8?

You have
if ( 1 == 1 )
for all that's worth.

And besides, you make sure a and sk8 are the same thing directly above that line, by assigning the current value of sk8 to a (discarding the typed-in value you had just read).

sk8 is the password.i initialize it char because is a character.sorry for my english but i dont know to speak verry well =[

so a=sk8; is not needed because i initialize it into if.wright?

yes. First initialize it

It's not needed because it doesn't do what you want. You've already gotten a single character read into a, and sk8 is garbage (you presumably want to initialize it at some point). Although why you want a single-letter password I don't know.

i dont know programming even C.i try to make something simple only for learn how to use if,char,int.the first steps =]

You need a good book and more reading. Your current understand is too weak for attempting any kind of programming with C.
Also, main must return int. So in effect, your
main()
must be written as
int main()
And for heaven's sake, indent your code!
