Freshman's Introduction to Computer Science
The following are some of the possible types of real questions and sample answers for the first year of computer science: ** 1. Computer system composition ** 1. ** Part of a complete computer system ** - A complete computer system consisted of a hardware system and a software system. The hardware system includes arithmetic units, controllers, memory, input devices, output devices, etc. The software system includes system software (such as operating systems) and application software. 2. **CPU components ** - The CPU was made up of two major components, an arithmetic unit and a controller. The calculator was responsible for arithmetic and logic operations, and the controller was responsible for commanding the various components of the computer to coordinate their work. ** 2. Storage related ** 1. ** Comparing the read and write speeds of different storage devices ** - Generally speaking, it was "Disk","Disk","Disk", and "Disk". The speed of the CPU was the fastest, and it was used to temporarily store the data that the CPU might access frequently in the near future to improve the operating efficiency of the computer. The RAM was used to temporarily store programs and data while the computer was running. The hard disk was used to store data for a long time, and its speed was relatively slow. The read and write speed of the soft disk was the slowest, and it was rarely used now. 2. ** Memory capacity (For example, what does the memory capacity of a micro computer refer to?)** - The memory capacity of a micro-computer mainly referred to the capacity of the random access memory (ram). The data in the RAM will be lost after the computer is powered off. When the computer is running, the program and data need to be loaded into the RAM before being executed by the CPU. ** 3. Data representation is related to conversion ** 1. ** Byte code related (e.g. how many different codes can be written in a single syllable)** - A character was composed of 8-digit digits. According to the principle of permutations and combinations, a maximum of 256 different codes could be written (2 to the power of 8 equals 256). 2. ** Numbering conversion (such as converting a decimal number to a decimal or hex number)** - For example, if the decimal number 27 was converted to a binary-based number, the result would be 11011. The decimal number 175 was converted to hex, and the result was AFH by dividing by 16. ** 4. Operating System ** 1. ** Operating System hierarchy ** - The operating system was divided into three layers according to its functional relationship: the system layer, the management layer, and the application layer. 2. ** Operations related to the operating system (such as the folder structure of the operating system, the operation of the trash bin, etc.)** - The tree structure was used in the folder structure of Windows. This structure had a clear hierarchy and was easy to manage files. When restoring a file in the trash, the restored file will return to the location where it was deleted. - In the windows menu, if there was a black triangle to the right behind a command, it meant that the command had a lower menu. ** 5. Office software related (Word, Excel, etc.)** 1. **Word document operations (such as font, font size default settings, view-related, etc.)** - In Word, the default font when creating a new document was Song, and the font size was 5. The WYSIWYG view was the page view. When editing a document in the page view, the display effect of the document was basically the same as the print effect. 2. **Excel operations (such as displaying problems in cell calculation results, entering text paragraph operations in cells, etc.)** - #########appeared after calculating a set of data in a cell of an Excel sheet. This was due to the lack of cell display width. If you enter two sections of text in the same cell in Excel, you should use Alt + Enter after the first section.

Freshman C language basic knowledge encyclopedia
The following is a summary of the basic knowledge of the C language: ** 1. Program structure ** 1. ** Function composition ** - C language programs were composed of functions, and there must be a function called main, which was the entry point for the program to start executing. In the C language, the main function was unique. Its basic structure was main() { }, and the contents of the function body were in parenthesis. Even if the function body was empty, the curly parenthesis could not be omitted. - Every statement in the function body had to end with a semi-colon (;), and the content in the curly brace was the part that the computer actually needed to execute. 2. ** Data Type ** - It supports a variety of data types, such as int, float, double, and character. 3. ** logical value ** - There were only two logical values: true and false. In the C language, non-zero values represented true and zero represented false. For any expression, a value of zero represents a false value, and a non-zero value (whether positive, negative, integral, or real) represents a true value. ** 2. Variant and constant ** 1. ** Variant definition ** - Before using a variable, you need to define the data type of the variable. For example, to define the int variables a, b, and sum, you can write int a,b,sum;. Then, you can assign a value to the variable, such as a = 20, which is to assign the number 20 to the variable a. 2. ** Constant ** - There were literal literals (such as numbers and characters written directly in code), and symbolic literals could also be defined in some ways. However, the basic concept of literals was that their values could not be changed during the running of the program. ** 3. In terms of operators ** - It contains arithmetic operators (such as +, -, *,/, etc. for numerical calculations), and relation operators (such as>,<,==,!=). , etc., used to compare relationships), logical operators (such as &||、! (used for logical judgment). ** 4. In terms of expressions and sentences ** 1. ** expression ** - It was a combination of variables, constant, operators, and so on. For example, a + b was an expression. After evaluating the expression, a result could be obtained. 2. ** Sentence ** - An expression or control structure ending with a semi-colon could be called a statement, such as sum=a + b, which was an assignment statement. ** 5. Control structure ** 1. ** Condition statement (if statement)** - It is used to execute different code blocks according to the conditions. For example, if (a>b) { /* code executed when the condition is true */ } else { /* code executed when the condition is false */ }. 2. ** Loop statement ** - **for loop **: for (initialisation expression; condition expression; update expression) { /* loop body */ }, such as for (int i = 0; i<10; i++) { /* code that is executed 10 times */ }. - **while loop **: while (condition expression) { /* loop body */ }. As long as the condition is true, the code in the loop body will be executed. ** 6. Arrays ** 1. ** Concepts and Subscripts ** - Arrays are a type of data. For example, an int array [10] is an int array containing 10 elements. The array index starts from 0, which means that the elements of this array are arrr [0], arrr [1],... arr[9]。 2. ** Random access feature ** - Arrays have random access characteristics, which means that any element in the array is accessed at the same time. This was because the element address could be calculated by adding the offset to the starting address of the array (the offset was equal to the index multiplied by the number of words occupied by the element). For example, for an array with an element type of int (assuming int takes up 4 words), the address of earl [3] can be calculated by adding 3*4 to the first address of the array. ** 7. Function ** 1. ** Function definition ** - When you define a function, you need to specify the function's return value type, function name, argument list, and function body. For example, int add(int a, int b) { return a + b; } define a function called add, which takes two int parameters and returns their sum. 2. ** Function Call ** - You can call a defined function in the program. For example, you can use int result = add(2,3) in the main function to call the add function and assign the result to the result variable. 3. ** Function parameters passing and value returning ** - The passing of parameters could be value passing (a copy of the actual value of the parameters is passed to the formal parameters in the function), and the function could return a value through the return statement (the return value type must match the return value type when the function was defined). ** 8. The scope and storage type of variables ** 1. ** Range ** - The scope of a variable determines the visibility and lifespan of the variable in the program. For example, a variable defined inside a function is called a local variable, and its scope is limited to the inside of the function, while a variable defined outside the function (global variable) can be used in the entire program file (without other restrictions). 2. ** Storage Type ** - The storage type determines how the variable is stored in the memory, such as auto (automatic storage type, generally used for local variables), static (static storage type, can be used for local variables to retain the value after the function call ends, and can also be used for global variables to limit its scope). ** 9. Pre-treatment process ** - Preprocessing instructions start with #. For example,#include is used to include the header file, which may contain function declaration, macro definition, and so on. For example,#include <stdio.h>is used to include standard input and output header files, so functions such as print can be used.
