Pointer question

Well, at first you should know that a pointer is an integer, the value of this int is the value of the adress it points to.
The only differnce between a "normal int" value and a pointer is the way they are read by a programm.
In c++ you can easily create a pointer to variable:

Code:

void main()
{
    char [] abc={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z};
    int pointer=&abc; //this is a pointer to abc it'll contain the adress of abc
    somemadeupFunctionThatTakesaPointer(*pointer);
    //well if you use pointer as a pointer you'll acess abc
    *pointer=c;
    //this line of code would write a c at the start of abc   
}

this code is just to get an idea of what pointers are, there are properbly mistakes in it and ofcourse it'll never compile ^^
