Exercise 1-17 Write a program that prints all input lines that are longer than 80 characters long.The code is as follows:#include //contains information about the standard library. #defineMaxRow 10//the maximum number of rows is 10 rows. #defineMAXLINE 100//the maximum number of characters per line is 100. intGetLength (Charcs[]);intMain ()//defines a function named Main, which does not accept parameter val

important. So we built a platform that incorporates programming and gaming. Our goal is to help developers from around the world-regardless of their experience or professional experience-to learn and improve their programming skills and find the ideal job in a game-like way.This excerpt from the official description page of the Codingame website, in short, focuses on writing game programs that emphasize the entertainment capabilities of the game and use it as a starting point to help us exercis

LinkedList classThe LinkedList class uses the linked list structure to save data, most of the methods are the same as ArrayList, but there are several ways to manipulate the end-to-end elements. void AddFirst (e E): Inserts the specified element at the beginning of this list. void AddLast (E E): Adds the specified element to the end of this list.

some guidance, I understand it. In fact, I have been thinking that the conversion process of the decimal number should have a mathematical formula derivation, which leads to the constant conversion of the decimal number, if you focus on the binary number, it's hard to understand. (There may be a mathematical formula, but instead of looking for a formula 15-> 10-> 4, it is easier to understand the process of directly observing the changes of binary strings) Let's look at the number (8 digits) of
