// This program shows some different functions that you can use to help 
// you manipulate anything to do with strings. You can find these functions
// in the standard library <string.h>. The functions we will demonstrate here
// are: strcpy (copy a string from one array to another - destination/source), 
// strlen(find length of a string), and 
// strcmp (compare two strings, return 0 if they are the same)

    //to another (destination, source):
    strcpy(word, "Sasha");

    //Example using strlen to find string length (returns int not including
    // '\0':
    int length = strlen("Sasha");
    printf("The size of the string Sasha is: %d\n", length);
    
    //Example using strcmp to compare two strings character by character: 
    //this function will return 0 if strings are equal
    //other int if not the same
