Segmentation Fault core dump..please help!

hi i wrote this program... it compiles with out any errors.. but when i try to run it in G++ compiller it gives the error "Segmentation Fault (core dump)"... i did a debug on visual c++
and it breaks at line 32 **which is marked below.

what the program does is, it takes 3 arguments, a number and 2 symbols,,, and draws a diamond...

it worked fine before i put the arguments to int main()..... can enyone point out the error for me please...i just have no friggin idea what went wrong

the codes are as follows......thanks :)...............

#include <iostream>
#include <stdio.h>
#include <ctype.h>
using namespace std;

void diamondrun(int * , char  , char );
void diamonddraw (int  , int , char , char );

cout << "size must be integer > 0" << '\n';
cout << "outside and inside must be single chars" << '\n';
}
else
{
cout << '\n';
cout << "starting diamond" << '\n';
