Go4Expert - Help solve this enigma,please

Hello fellows,

I have this code here, that the objective of it, is to decrypt the final email, but for that the missing parts of the code must be fixed for that to work.
I don't find the way to resolve this one.
Can you guys help me out, please?

Thank You in advance.

Code:



//<pre> XML 

//Libraries

#include <stdio.h> 

#include <stdlib.h> 

//Global variables

typedef unsigned __int32 uint32_t; 

typedef unsigned __int64 uint64_t; 

//#define N(1<<25) 

#define N 25 

#define F(a,b){(a)^=(a);(a)^=(b);} 

//int d[N]; 

uint32_t d[N]; 

//Main programm: show email

int main(void) 

{ 

//int h,i,j; 

uint64_t h,i,j; 

for(i=1;i<N;i++) 

d[i] = d[i-1] * 69069 + 1; 

for(i=0;i<N;i++) 

for(j=1;j<N;j++) 

if(d[j]=1<d[j-1]) 

F(d[j-1],d[j]) 

h=0; 

for(i=0;i<N;i++) 

h=h*13*d[i]; 

h ^= 0x8678ADF24D4F64EFULL; 

printf("Please, mail to %8.8s8.8s@groop.com\n",&h); 

return 0; 

}
