he backslash \ tells C to print the character following it, in this case a quote " and not to treat it as a closing quote for the one at the start of the printf statement. You can use the backslash for literal characters e.g. \" is a quote, or for special characters \n is a new-line, \t is a tab

the %s tells the printf to replace he %s with the variable given, in this case word, and to print it as a string, i.e. to interpret the variable word as a list of characters.

Whats the purpose of \"%s\"?
