How to compile notepad into c

Configure the compiler (Recommended learning: notepad use)

Download and install MinGW from the official website

change:

Select "mark for installation" of "mingw32-gcc-g -bin" and select "Apply Changes" of "Installation" in the upper right corner. There were no other problems when I didn't install the other items. Later, other problems arose and I had to ask for insurance before installing them. In total, just under 400MB was installed.

Edit environment variables

Control Panel\All Control Panel Items\System, Advanced System Settings→Environment Variables, Look for the PATH variable in the "Administrator's User Variables" column. If there is none, create a new one. If there is, edit it. The variable name is "PATH". Add "C:\MinGW\bin;" to the variable value based on the original value. This value is the same as each Personally, it depends on the location where MinGW is installed, which varies from person to person. The significance of ";" is that when the value of PATH has multiple items, use it to separate these items.

Two methods to check whether the first two steps are successful

Enter the cmd console and enter gcc -v or g -v to view The compiler version that has been added to the environment variables. It is normal to display the content in the yellow box, indicating that the first two steps were successful. Create a simple C source code file and make sure the code runs correctly. For example, Hello.cpp:

//Hello.cpp
#include<iostream>  
using namespace std;
int main()
{
    cout<p> In the cmd console cd to the directory of the source code, then execute g Hello.cpp -o Hello.exe, and then execute the Hello.exe /k command. It can run normally. It shows that the first two steps are fine. <br>The former command is to use the g compiler to compile the source code and output the exe file to this directory. The latter command is to run the exe file (the /k parameter makes it stay in the program interface after running, while /c will cause It is closed. That is the comparison between keep and close). The first two commands can actually be combined into one using "&&", that is, g Hello.cpp -o && Hello.exe Hello.exe /k. <br>We are already more than half successful here, because as you can see, you can already compile and run the source code in the cmd console. To give Notepad this ability, you only need to let Notepad "execute the currently opened source file with cmd in one step" Compile and run commands" only. </p>
<p><strong>Notepad adds run command</strong></p>
<p>Open Notepad and press F5 to bring up "Run". Copy the command mentioned later and run it. It is recommended to save it with any name. </p>

<p>You can also find "Run (R)" in the toolbar </p>
<p>Referenced a lot of information about Notepad run commands and cmd commands, modified My last command is </p>
<pre class="brush:php;toolbar:false">cmd /k pushd "$(CURRENT_DIRECTORY)" && g++ -o "$(NAME_PART).exe" "$(FULL_CURRENT_PATH)" && "$(NAME_PART)".exe & PAUSE & EXIT

(no branch, it is a whole command). To understand this command, you can divide it into six, that is:

cmd /k: open cmd console, let it stay after running the program without automatically closing.

pushd "$(CURRENT_DIRECTORY)": Change the working path to the path where the source file is located. For example, 'pushd E:\kkk' is equivalent to e: and then cd kkk in cmd. This command is in the source code This is especially important when you want to call a file in the same directory and only write a relative path. Because Notepad's default working path is its own installation path.

g -o "$(NAME_PART).exe" "$(FULL_CURRENT_PATH)": Call the compiler g .exe in the environment variable to compile the source code into an exe file with the same name and output it to the same path.

"$(NAME_PART)".exe: Run the executable file compiled from the source code.

PAUSE: Pause, prompt "Press any key to continue", and cooperate with the next command to achieve the effect of "Press any key to close". If neither of them is available, the program will close in seconds after running.

EXIT: Close the cmd console. If not, press any key to return to the cmd command console, waiting for the next command to be entered.

$(CURRENT_DIRECTORY) represents the path of the directory where the file is located.

$(NAME_PART) indicates the file name without the suffix part of the file.

$(FULL_CURRENT_PATH) represents the current complete file path.

Double quotation marks (half-width): used to prevent directories or file names from containing spaces.

"&&" and "&": The former means that the next command will be executed after the previous command is executed normally, and the next command will not be executed if it is abnormal; there is no need to worry about the latter. For example, the last two subcommands after dividing into six means that regardless of whether the source code is compiled and run successfully, the words "Press any key to continue" will appear, and the cmd console will be closed after pressing any key.
