Pointer's error?

Development Tools IDE 1.x

Hi everyone, I'm very new to C coding.

I was just wondering what the mistake is in this code please:

void main()
{

int *p;
int a;
a=20;
*p=a;
printf(“%d”, *p);

}

Thank you

What error are you seeing?

I can guess, but you tell me.

p is allocate, *p is not.

p contains a address (pointer) but you did not allocated a space and attributed the beginning of that space to p

Right.

Sorry man! I missed that there. I haven't compiled it because I haven't got a compiler on this computer.

It is a waste of your time and ours until you get serious about programming and install compiler on your PC.
