I’m trying to write a piece of code that will read user input, store it inside a double or a char depending on the input’s type. It works fine, unless I input “i”, “j”, “I” or “J”. These characters are read correctly if the first scanf looking for doubles does not run. What’s happening?

Why when I run this code:

I wonder why the following code does not work as I expect:

I cannot save information of students from file to struct, When i tried to printf my struct its not working, I think it should work but i dont understand, why it is not working. When i did only struct or use file like this it works.

I am learning C language. This is my code run in linux.

I’m trying to parse this string:

when i input “yy” scanf() uses the second y automatically and doesn’t wait for another char input.
