Great tip Striver bhaiya but those who don't want to do these much set-up they can just install one chrome extension "CPH for Competitive programmers" this extension will automatically access test case and run it for all test case in your VS code system.

[IF ANYONE WANTS TO KNOW WHAT'S HAPPENING] This video is awesome! Just wanted to break down what's happening behind the scenes: The trick is to use tasks.json to redirect the default input stream to cin. Notice the command line options uses '' for output.txt. Those are actually compiler flags for g++! Super cool trick. 👍 For reference, see the value of tasks[1]["command"] in tasks.json at line 22 visible at the 5:21 mark in the video. I am just adding context to the magic! Thanks again for sharing.

So, yeah for me, it wasn't as simple as that but the AI ChatGPT, helped a lot. In my case, the code was compiling and running if both are done separately, Ctrl + Shift + B compiled the program and Ctrl+Shift+P > Run tasks > Run with input or output used to put the output in Output.txt. ChatGPT said the following steps, will work according to the case that C++ file is main.cpp ,input file is input.txt ,and output file is output.txt 1. Create the file build_and_run.bat and write the prompt in it @echo off g++ main.cpp -o main.exe main.exe < input.txt > output.txt 2. Next, change the json prompt to the following: { "version": "2.0.0", "tasks": [ { "label": "Compile and Run with Input and Output", "type": "shell", "command": "${workspaceFolder}\\build_and_run.bat", "group": { "kind": "build", "isDefault": true }, "detail": "Compiles and runs the program with input redirection and writes output to output.txt" } ] } The next time you use Ctrl + Shift + B, it will compile and run too. Hope it helps 👍

Day 1: Introduction to DSA and Environment Setup Download the vs code required extensions then set-up your ide Day 1: Setting Up Your IDE Like a Pro Introduction When starting your coding journey, having an organized environment can significantly boost your productivity and ease the debugging process. Today, we’ll walk you through setting up your IDE using a JSON file to manage your coding files, input, and output separately. We’ll cover setups for Java, C++, and Python. Step 1: Why Use a JSON File? Using a JSON file to organize your projects helps in keeping your code, input, and output files separate, making it easier to manage and test your programs. It also allows for easy switching between different languages and projects. Step 2: Creating Your Project Structure (It can vary on every individual this is just an example) First, let’s create a directory structure: bash Copy code /my_project ├── code/ │ ├── main.cpp (or main.java, main.py) ├── input/ │ ├── input.txt ├── output/ │ ├── output.txt ├── config.json • code/: This folder contains your main source code file. • input/: Place your input files here. • output/: Your program’s output will be stored here. • config.json: This file will manage the paths and commands for running your program. Step 3: Writing the JSON Configuration Note : for windows users : it will not work if your default terminal is Powershell make it cmd then it will work. to change default terminal : press->clt+shift+p->write:default terminal->change it to cmd Create a config.json file in your project directory. C++ : { "version": "2.0.0", "tasks": [ { "label": "Compile and run C++", "type": "shell", "command": "g++", "args": [ "-std=c++17", "-O2", "${file}", "-o", "${fileDirname}\\${fileBasenameNoExtension}.exe", "&&", "${fileDirname}\\${fileBasenameNoExtension}.exe", "", "output.txt", "&&", "del", "${fileDirname}\\${fileBasenameNoExtension}.exe" ], "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$gcc"] } ] } For Java: { "version": "2.0.0", "tasks": [ { "label": "Compile and run Java", "type": "shell", "command": "javac", "args": [ "${file}", "&&", "java", "-cp", "${fileDirname}", "${fileBasenameNoExtension}", "", "output.txt" ], "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$javac"] } ] } Python: { "version": "2.0.0", "tasks": [ { "label": "Run Python", "type": "shell", "command": "python", "args": [ "${file}", "", "output.txt" ], "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$python"] } ] } These configurations will work for their respective languages, using input.txt for input and writing to output.txt for output. Conclusion With this setup, you’ll have a neatly organized workspace where your code, input, and output are separated, making testing and debugging your programs easier. This structure is a best practice for professionals.

Thanks Striver 🙌 For C++ & JAVA was facing some errors of syntax in tas.json file on windows. Pasting working json This will dynamically take the file that is active and you are working and run that. { "version": "2.0.0", "tasks": [ { "label": "Compile and run", "type": "shell", "command": "cmd", "args": [ "/C", "g++ \"${file}\" -o \"${fileDirname}\\${fileBasenameNoExtension}\" && \"${fileDirname}\\${fileBasenameNoExtension}\" < \"${workspaceFolder}\\input.txt\" > \"${workspaceFolder}\\output.txt\"" ], "presentation": { "reveal": "never" }, "group": { "kind": "build", "isDefault": true }, "problemMatcher": { "owner": "cpp", "fileLocation": [ "relative", "${workspaceRoot}" ], "pattern": { "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$", "file": 1, "line": 2, "column": 3, "severity": 4, "message": 5 } } } ] } For those who want the same configuration for JAVA Make sure you have jdk installed and added in path { "version": "2.0.0", "tasks": [ { "label": "Compile and run Java", "type": "shell", "command": "cmd", "args": [ "/C", "javac \"${file}\" && java -cp \"${fileDirname}\" \"${fileBasenameNoExtension}\" < \"${workspaceFolder}\\input.txt\" > \"${workspaceFolder}\\output.txt\"" ], "presentation": { "reveal": "always" }, "group": { "kind": "build", "isDefault": true }, "problemMatcher": { "owner": "java", "fileLocation": [ "absolute" ], "pattern": { "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$", "file": 1, "line": 2, "column": 3, "severity": 4, "message": 5 } } } ] }

hi need help figuring out that i followed each and every step very carefully but still i get errors like the code ended with error and so on and i really cannot figure out anymore how to resolve the issue also there appeared to be no errors in the problems section this is the error that i get : The terminal process "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command g++ -std=c++17 -o "demo" "C:\Users\Dell\OneDrive\C++\demo.cpp" && .\demo < input.txt > output.txt" terminated with exit code: 1. * Terminal will be reused by tasks, press any key to close it. would appreciate any guidance

[@Goutam-tr2ls]

I'm also having similar problem 😢

[@abhinavpandey840]

you are doing a mistake as you are running in windows powershell terminal and not in command prompt terminal and in new version of vs code you cannot change your default terminal as shown by other youtubers, for changing try following this steps: 1: Go to setting icon of vs code in lower left corner. 2: Go to setting option (where shortcut is showing ctrl+,). 3:search for default terminal. 4: here select the default terminal profile for Windows and change it to command prompt. NOTE : You need to change from workspace (it is just below the search bar where you had type default terminal) ,if you change from user side it will not change ,also it was the error from the beginning because you were changing default terminal from the user side and not the workspace side

[@abhinavpandey840]

i can tell you are running in powershell terminal because it is written in your path C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe (see you are running in powershell.exe) if you were ran this code in command prompt it had shown cmd.exe and striver bhaiya already said you have to run in command prompt terminal for working and not in powershell terminal
