Hello world obfuscated

I encountered the following code

#include <stdio.h>

int main(void)
{
    long long P = 1,E = 2,T = 5,A = 61,L = 251,N = 3659,R = 271173410,G = 1479296389,
              x[] = { G * R * E * E * T , P * L * A * N * E * T };
    puts((char*)x);
    return 0;
}

The case is I do not quite understand how it works,It is very confusing to me. Can someone you please explain this in detail?
