Strange behaviour of a character in a structure while printing

[ZuLuuuuuu]

Hello, I have a strange problem or the problem is very obvious and I can't see it :) I'm kind of a new C programmer so the chance of the latter is more :)

Anyway, I have a structure like this:

#define EN_COK_HECE 40
 
struct kel
{
    char kelime[EN_COK_HECE];
    char sesliHarfler[EN_COK_HECE];
    int sesliHarfKonumlari[EN_COK_HECE];
};

And on my program I use a code like this:

printf("%i ", (kelime->sesliHarfler)[2]);
printf("%i ", (kelime->sesliHarfler)[2]);
 

Yes, same line 2 times. But the strange thing is that they print a different output. The output is like "97 -112". And when I add the same line several times more it does not change (97 -112 -112 -112 -112...). So just the first statement changes the value of the character. But I just do printing, I don't do any assignments, so I cannot understand where the problem is.

I am using Windows platform with MinGW system. And the code above is plain C.

You are trying to print a single character from a character array and instead of using %c you are using %i(i cant find out what is %i).
It is is printing the ASCII value of the character.
Try to use %c instead of %i and try to run ur code.

I did it for debugging purpose. When I change it to %c then I get different characters like getting different numbers:

a Ê Ê Ê Ê Ê....

First one is what it should be but I don't know why it changes into Ê nor continues that way instead of keeping to change everytime I use that statement.

Kelime is pointer to structure kel. Then check weather you have allocated memory for that pointer(kelime). Then try to access that variables, It will work fine.

Yes, the problem was that I didn't allocated memory for my local variable, which is destroyed when the program returns to the main() function. Thanks...
