Define a string var using char.
In C , string var is not like the python.
You have to declare it first , then make a pointer to the exact string.

At the end of each string , the system will add “\0” at the end. You could use sizeof() func to show its length.
Example Code: see practice_c2.c
Use %s to fill the blank instead of %c , otherwise you will get an error notification from both the compiler and the Clion IDE.
