What went wrong? The compilation can be passed,

publi class void main(string args). public static void main(string args)

Estimate what you want is to add up from 1 100, odd to add, even to add, and there are a few other things to change.

public class jiafa{

public static void main(string args)

int sum1=0,sum2=0,sum3=0;

for(int i=1;i<=100;i++)sum1+=i;

for(int i=1; i<=100;i++)if(i%2!=0) sum2+=i;

for(int i=1; i<=100;i++)if(i%2==0) sum3+=i;;

scanf("%d",a);The following is removed, and the &scanf function before a is a standard library function, and its function prototype is in the header file". Like the printf function, C also allows you not to have to include a file before using the scanf function. The general form of the scanf function is:

scanf("Format Control String", address table column);

The formatting control string functions the same as the printf function, but it cannot display the unformatted string, that is, the prompt string cannot be displayed. The address of each variable is given in the address table column. An address is made up of the address operator "&" followed by the variable name.

The error is due to the fact that the rendering of the old punch program is selected with the wrong room selection, and it should be selected as the mercury playback engine.

1. Find Premiere on your Windows computer, open the Premiere post-editing software, find the file at the top of the Premiere window, and click Open File.

2. Open the drop-down menu in the Premiere file menu and select Project Settings.

3. Select Project Settings in the File menu, click on the menu bar on the right side, and select Open General.

4. You will enter the general setting work window of Premiere, at this time, you can see that the renderer program of Premiere is selected as Mercury Playback Engine GPU acceleration (OpenCL).

5. Click on the renderer window, and the drop-down menu will pop up, and then select only the Mercury Playback Engine software.

5. After selecting Mercury Playback Engine Only, click the confirm button below to solve the problem of error when compiling the video and acceleration renderer error.

That's the hell the computer configuration is too low.

A compiler is a translation program that is used to translate a program in the source language (i.e., written in a programming language) into a program in the target language (i.e., written in a pseudo-machine** in binary numbers). The latter is under the Windows operating system platform, and its file extension is usually . obj。

The file usually goes through further connections to generate an executable file (a program written by a machine with a file extension. exe）。There are usually two ways to do this translation, one is compilation and the other is interpretation.

The latter does not generate an executable file, but only translates a statement and executes a statement. Compiling these two ways is much faster than interpreting them.

2. The five stages of the compilation process: lexical analysis; grammatical analysis; Semantic analysis and intermediate ** generation; Optimize; Target generation.

3. In these five stages, the task of lexical analysis is to identify whether there are errors in the words in the source program, and the part of the compiler that implements this function is generally called the lexical analyzer. In a compiler, a lexer is usually only a subroutine of a grammar parser to be called when it needs word symbols. Source program errors found during this compilation phase are called lexical errors.

4. The purpose of the grammatical analysis stage is to identify whether the grammatical structure (i.e., sentences or sentences) of the source program is wrong, so it is sometimes often sentence analysis. The program that is responsible for this function in the compiler is called a parser or parser. Errors found at this stage are called grammatical errors.

5. The (source) program of C language must be compiled to generate the target**, and then linked before it can be run. The source code of Pascal and Fortran also goes through this process. Languages such as C, Pascal, and Fortran are often referred to as high-level languages.

The final executable program is called a machine language program.

6. In the process of compiling a C language program, if an identifier in the source program is found to be too long, beyond the scope allowed by the compiler, this error should be found in the lexical analysis stage, and this error is usually called lexical error.

The task of the lexical analyzer is to identify the words and their attributes of the input source program based on the lexical rules, and identify the word symbols one by one.

The input of lexical analysis is the source program, and the output is a special symbol of each word, called a token (token or symbol).

There are two types of parsers: bottom-up and top-down. Commonly used parsers are:

The recursive descent analysis method is a top-down analysis method, the operator-first analysis method is a bottom-up analysis method, the LR analysis method is a bottom-up analysis method, and so on.

Lexical rules of programming languages are usually described in formal grammar or formal forms, while context-independent grammar is used to describe the grammatical rules of programming languages.

In the grammatical analysis phase, the input data processed is the word symbols from the lexical analysis phase. They are lexical analysis.

Compiling through just means that there are no syntax errors, and if you can't run the result, it's your **logic problem** to take a look at it, and debug it yourself with a breakpoint.

while(r=!0)

Write it the other way around, r!= 0

Otherwise it's a cycle of death ...
