Delete Conda Environment (7 commands)

In this article, we have explained and presented 7 commands to delete a Conda environment permanently. We can delete a conda environment either by name or by path.

C++

Return value of main() in C / C++

The return value of main() function shows how the program exited. The normal exit of program is represented by zero return value. If the code has errors, fault etc., it will be terminated by non-zero value.
