C :: How To Initialize Variable Word In Separate Statement From Its Declaration

I wrote the following program to initialize a string after the variables is declared, but it isn't working. A warning is given by the compiler, and the execution of the program shows a strange string. How do I initialize variable word in a separate statement from its declaration?

Code:

#include <stdio.h>
int main( void )
{
char word[20];
*word = "Hello";

printf( "The string is %s.
", word );
return 0;
}
