Iam writing a Cpp program to read the contents of a file. Iam doing this in my Redmi note 5 Pro Android 9 , oreo through Termux app [rooted].
The thing is it is not recognising my absolute path, but it is able to work with the files in my source code's directory , ~ is my root directory( in my case the home is root.) My Cpp file should be able to locate my file ~/sdcard/b.sh , but it is failing to do so, i wonder why?

This is my code:

After i run this in the terminal
Terminal:

That's a good question, i actually tried an alternative to locate the root directory '/' , but it still landed at the same result.
I tried, " '/'/sdcard. i included '/' instead of / to diffrentiate from the path slash and root slash

PS: Is there any other alternative way that i can try?

First of all, don't create files in root. Start by having the code print which user is running the code so you know which user you need to set the permission to allow writing.
second, try using command lines to do what you want to do to make sure it is even possible (create a directory in a particular directory). Try changing permissions (chmod) as needed and see if It works.
If nothing works and your Android system is locked down somehow, you'll need to somehow make a space that allows you to write from command lines before you bother writing code.
