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>
