C++ Compiler not working

Thank you for reaching out.

From the information shared, it looks like the issue might be that the executable file is not getting created or not being recognized by the system. To better understand what is happening, please check if test.exe is present in your folder after running the g++ command. Also, kindly share the output of the dir command and let me know if you see any errors during compilation. This will help me assist you further.

PS C:\Users\Prabh\OneDrive\Documents\Prabhjoat University\programming\Microsoft C++ Course> ./test.exe

./test.exe : The term './test.exe' is not recognized as the name of a cmdlet, function, script file, or operable

program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

At line:1 char:1

• ./test.exe

• 
      + CategoryInfo          : ObjectNotFound: (./test.exe:String) [], CommandNotFoundException
  
      + FullyQualifiedErrorId : CommandNotFoundException
  

In PowerShell, the current directory (.) is not on the PATH by default, so running test.exe without a path fails even though the file exists.

Use one of these options from the same folder where test.exe was built:

1. Prefix with ./ (recommended in PowerShell):

      PS C:\Users\Prabh\OneDrive\Documents\Prabhjoat University\programming\Microsoft C++ Course> g++ test.cpp -o test.exe
      PS C:\Users\Prabh\OneDrive\Documents\Prabhjoat University\programming\Microsoft C++ Course> ./test.exe
   

2. Or specify the full path:

      & "C:\Users\Prabh\OneDrive\Documents\Prabhjoat University\programming\Microsoft C++ Course\test.exe"
   

If the compiler command succeeds but test.exe is not created, list the directory contents to confirm:

PS ...> dir

If test.exe is missing, fix any compile errors first, then run it as above.
