Function pointers

[aewarnick]

As of yet, I see no use in function pointers. I cannot get it to work. Can anyone figure out why? I am trying to learn how to use them just in case. But just please let me know if they are useless of not.

#include <iostream>
#include <cstdlib>
#include <cstring>
char funk1(char[], const int, char (*)(char, char));
char funk2(char[], char);

int main() {
const int size=100; int h=2;
char g[size]="Hi";
char n[size]={0};

cin.getline (g, size);
cin.getline (n, size);
funk1(g, size, funk2);

system("PAUSE");
return 0;
}

char funk1(char gg[], const int asize, char (*p)(char, char)) {

(*p)(char gg[0], char asize);
}

char funk2(char x[], char y) {
if (strlen(x)<8)
cout<< "xless";
if (y<8)
cout<< "yless";
}
