QUESTION
I just got into C programming and learning in CS50. I was trying to convert the char
generated from the card number into an integer that I can sum with. Basically, I'm looking for an equivalent for Java's charAt()
in C.
ANSWER

is for converting strings (sequences of characters terminated by a null-character) to integers, not for converting characters.
To convert decimal characters to corresponding integer, you can subtract '0'
(the character code for the characer 0
because character code of decimal characters are defined to be continuous in the C specification.
In conculsion, you should replace the two atoi(cardNumber[i])
s to (cardNumber[i] - '0')
.

Blowfish is not supported by all Linux distros, like Ubuntu:

Debian does not support blowfish in crypt as of Debian 10 but should be able to do it in the next release, moving the dependency of crypt from glibc to libxcrypt:

ANSWER
Answered 2021-Apr-17 at 16:53This answer is for everyone, who wants to install powerline only in vim in the windows terminal (using wsl Ubuntu 20.04). It took me quite some time.
The reason why I had this issue was that glyphs where missing in the windows terminal font. I tried to install the powerline fonts according to the documentation(https://powerline.readthedocs.io/en/latest/installation/linux.html#fontconfig) as @romainl suggested but that didn't work. Furthermore I tried to install all powerline fonts from the github(https://github.com/powerline/fonts), I ran both the installation scripts. The one for windows in the powershell console according to this blog() and the one for Linux on the Ubuntu WSL Machine according to the documentation. Didn't work either.
Then I stumbled upon a blog post of Microsoft(https://docs.microsoft.com/en-us/windows/terminal/tutorials/powerline-setup), where the person installed a theming framework oh-my-posh. However, I neither wanted to install a theming framework nor a special version of git. Furthermore I only wanted to install powerline in vim not in my whole console. This was the moment when I asked myself: did I miss something? And indeed I did catch a little detail. The answer was to install a the Cascadia Mono PL font (https://github.com/microsoft/cascadia-code/releases) which includes the missing glyphs. Just download the zip and double click on the font. Furthermore I had to set the fontface in the setting.json of the windows terminal (which can open with pressing (CTRL + ,
) in the terminal). Your settings should look something like this:
