Is it difficult to use the second level C language, and is the second level C language difficult?

It's not difficult, I didn't pass the written test for the first time, but it's just 60 on the computer, as long as you are careful, because you can at least know the right and wrong of the program on the computer.

It's simple! As long as you read the book carefully, you will definitely be able to get by.

Good luck with the exams.

It is recommended that you make up a bedtime story for children:

Pony and his mother live by a beautiful creek with green grass. Except when his mother crossed the river to deliver food to the village on the other side of the river, he always followed his mother's side every step of the way.

He was happy, and time flew by.

One day, Mom calls Pony to her side and says, "Pony, you're grown up and can help Mommy." Today you can send this bag of grain to the village on the other side of the river. ”

The pony happily agreed. He hurried to the creek with the grain. But there was no bridge over the river, so I had to cross it by myself.

But I don't know how deep the river is. The hesitant pony looked up and saw Uncle Niu grazing not far away. The pony hurriedly ran over and asked

Uncle Niu, do you know how deep the water is in that river? ”

Uncle Niu straightened up his tall body and said with a smile: "Not deep, not deep." It's just down to my calves.

The pony happily ran back to the river, ready to cross it. As soon as he stepped on his legs, he heard a voice say, "Pony, don't go down, this river is deep."

The pony looked down and saw that it was a baby squirrel. The little squirrel cocked her beautiful tail and opened her round eyes, and said very seriously

Two days ago, one of my buddies accidentally fell into the river and the water swept him away. The pony was out of ideas. Uncle Niu said that the river is shallow, and the little squirrel says that the river is deep, what can I do? I had to go back and ask my mother.

From afar, the mother saw the pony come back with her head down and carrying the grain. Thinking that he must be in trouble, he goes over and asks the pony. Pony cried and told his mother what Uncle Niu and the little squirrel had said.

Mom comforts the pony and says, "It's okay, let's go and see it together." ”

Pony and Mom go to the river again, and Mom lets Pony test how deep the river is. The pony cautiously probed and flowed across the river step by step. Oh, he understood, the river was neither as shallow as Uncle Niu said, nor as deep as the little squirrel said.

You will only know if you have tried it yourself.

Pony glanced affectionately at her mother and said, "Thank you, good mother." ”

Then he turned and ran towards the village. He's especially happy today, do you know why?

Level 2 wants to get a high score;

The written test relies on super memory;

The machine relies on luck and a little memory;

Generally, those who take the second level exam are lucky;

If you just want to get on the plane, it's very easy;

However, before the exam, I still practice the computer-based questions;

It's not difficult, do a few sets of real questions before the exam, make sure you understand them, test them on the computer if you don't understand, and practice programming on the computer, basically no problem.

Introduction to the Level 2 C Language for Computer Science:

National Computer Grading Examination Level 2 C Language is a book published by the Electronic Industry Publishing House in June 2009, the authors are Guiyang, Wang Gongming. This book is mainly based on the past test questions, using the method of statistical analysis, to scientifically make conclusions on the questions and the future trend of the questions.

Based on the past test questions, using the method of statistical analysis, scientifically making conclusions and future question trends is a major feature of this book. This book can ensure that the necessary knowledge points of the exam are not missed, and the burden of test takers is not increased, so that test takers can easily and happily grasp the knowledge points and understand the true meaning of the Level 2 C language test.

With a book in hand, you can pass the test without worry". For the computer-based test, after an in-depth analysis of the content of the computer-based test question bank, the author of this book has carefully organized 5 sets of full-scale mock test questions, which involve all aspects of the content of the previous exams.

This book can be used as a review book for taking the National Computer Grading Examination - Level 2 C Language Examination, and can also be used as a reference book for learning C language.

The national computer level 2C language programming includes 40 multiple-choice questions (one point for each question) and three operation questions (60 points).

In the multiple-choice questions, 1 10 questions are about Level 2 common basic knowledge, and 11 40 questions in the multiple-choice questions are in the C language.

The operation questions include one question each of the program fill-in-the-blank (18 points), the program error correction (18 points) and the programming question (24 points).

Fill-in-the-blank is the process of removing two or three places from a complete program for the candidate to fill in completely. Due to the different questions drawn by each candidate, there are 2 to 3 blanks to fill in the blanks.

Procedural error correction is also a complete procedure, in which there are 2 3 errors that require the candidate to correct them.

Programming questions are the result of asking candidates to write a program and then run the stem requirements. The main function main() will be given in its entirety, and the fun() function will be called in the main function, and the fun function will be written by the candidate himself. Programming questions are scored based on the results of the run, and they must be run after the writing is completed, otherwise there will be no points.

The Level 2 C Programming exam involves two parts: common basic knowledge and C language. The content of common basic knowledge includes four parts: data structure and algorithm, programming basics, software engineering basics, and database design basics. Each of the 10 multiple-choice tests is worth 1 point.

The C language has four major parts: basic knowledge (C language overview, constants and variables, data types, operators and expressions), three major programming structures (sequential structure, selection structure, and loop structure), arrays, functions, and pointers, and other contents (preprocessing commands, structs and commons, bit operations, and files). The focus is on the first.
