Can you explain elaborately how to use time?

my command in wsl :

I'm using x64 Windows 10 and ubuntu as wsl2.

• Executing task: copy "C:\Users\shaik\OneDrive\Documents\New folder\hello.cpp" 'C:\Users\shaik\OneDrive\Documents\New folder\jspwTest.cpp' && g++ jspwTest.cpp -o jspwTest && jspwTest < input.txt > output.txt && del jspwTest.exe && del jspwTest.cpp

Whatever setting you've mentioned over here I have done all exactly but it's not working
when I press ctrl + shift + B then in downward something like building is happening for 5 seconds then it also stops
Please tell me how I can resolve this issue...

P.S. I use Windows OS(64-bit)

Here's my folder structure

Hello
I recently discovered that when i am trying to run task in learn.cpp it is working fine but when I run same task in learnC++.cpp it showing me an error
Does anyone has any idea how I can solve this problem ?
i am using the latest tasks.json file and cmd as default shell

I had recently updated my laptop and PowerShell would also have had been updated with that. Currently there were two errors

1. "&&" was not being recognised but it was corrected using "-and", I don't know if it will work or not but yes.
2. I have attached the image of the associated error where it is showing "The '<' operator is reserved for future use."
   

hey
after adding code in the tasks.jason file and performing all the steps as it is the termial shiw the following errors
and even when the errors are solved the output.txt file does not show the output with the input.txt file input

I was following the tutorial for getting everything working on Windows. I was wondering if it would be possible to make it, so that we can use PowerShell instead of having to set the default terminal as CMD?
