A string in C is nothing but a one-dimensional character array whose last character is a \0 or null character. The %s conversion specifier is used with scanf() and printf() for getting string input and displaying output. For getting a line of text, the %[^\n] conversion specifier is used with scanf().

char arr[100];
scanf("%s", arr); /*compiler automatically appends \0*/
printf("%s", arr);

You will find out who has the longest first name in your section! Your section name list can be found in files named "l1p1.txt", "l2p1.txt", etc., and is stored in the directory /home/sharing/. Copy this file to your directory if you wish to. Your program should read the data (names) from the file, print out the longest name and the length of the longest name. Additionally, it should also print out how many total names were stored in the file.
