============================================== 1.16 Print length of arbitrary long input line ============================================== Question -------- Revise the main routine of the longest-line program so it will correctly print the length of arbitrary long input lines, and as much as possible of the text. Solution -------- .. coderun:: cprogs/ex_1.16_longline.c :language: c Explanation =========== A string in C is a character array which ends in `\0`. getline is a function in our program, which reads one character at a time using getchar and stores it in a character array called s[] and it returns the length of the array. We keep track of each line and it's length using a variable, `max`. If the length of the line is greater than `max`, then we copy that line into the `maxline` using a copy routine. At the end of the program, whichever was the longest line that was copied in maxline array, we just print that. Visualize the Concept --------------------- .. raw:: html
