Answer 1

i'm not very good at c# but here is what i can find.

while statement use lowercase w. not While but while.

ReadLine doesnt take parameter. unlike python in here you need to print the message beforehand

last you cant declare same variable inside each case in switch. instead declare it before the switch statement
int result = 0
//switch here

Thanks, you’re right on the 1st and 3rd point. After a few failed attempts, I’ve figured out/come to the conclusion that you can’t, for some reason, reassign variables like you can in Python by redeclaring them.

Adding int result=0; before switch statement causes an error.

Also, doing
int result=0
int result=1
produces an error

So I think I meed to get rid of “int” before “result” in the switch statement

Answer 3

This is true. In c# a variable is declared once. Redeclaring a varable is not allowed.

You can assign another value to the variable as many times you like.
1) int result=3; //declare variable and initialze
2) result=4; //assign another value
3) result=5; //assign another value
4) Console.WriteLine(result);//display value
