Here it is a little clearer [hopefully?]

#include <stdio.h>

// x will be 1 (the name of this app would be in argv[0]) if we
// don't invoke the app with some args.
//
main(x)
{
char c;

// zero then!
//
--x;

while(c = "J!Mpwf!Zpv\1"[x])
{
// No need for the -1 if we add 1 to the literal's characters...
//
// "I Love You\1"
//
c = c - 1;

x++;

putchar(c);
}
}
