Everytime I open terminal it's in cat.

Hey,

So i am a bit of a noob and wanted to install C/C++ compiler MinGW-w64 to run C in VS Code.

When I did it I used couple of commands in terminal:

- arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

- arch -x86_64 brew install MinGW-w64

After this when I opened my terminal it's default state is "cat". When I press CONTROL + C I am no longer in cat "editing" but where I had to be. (pictures shows before and after pressing CONTROL + C)

My question is how to I revert things back to normal. Thanks in advance !!
