Thread: newbie question

I have an exam on C coming up and one of the past papers has the following question:

we have this loop :

Code:

for( i = 0; i < 127 && (c=getchar()) != '\n'; i++)
        s[i] = c ;

the question is:

If the user types in a line of text at the keyboard and presses ENTER what statement must be placed after the for loop to ensure that the array s contains a properly teminated string containing exactly what the user just entered (excluding the newline)

any help would be greatly appreciated

s[i] = '\0';
