Question

Answer 1

This is a quirk of the c-language.

It is not allowed to have a
declaration like
int num;
directly after a case statement

//not allowed
case 2:
int num;
printf("\nYou Entered 2 :\nEnter any number to check whether it`s odd or even : ");

//allowed
case 2:
printf("\nYou Entered 2 :\nEnter any number to check whether it`s odd or even : ");
int num;

//allowed and a very good practic use brackets!!
case 2:{
int num;
printf("\nYou Entered 2 :\nEnter any number to check whether it`s odd or even : "); }

It worked fine. I entered the following lines for 4 different runs:

Got 11, -1, 30, and 0 as answers all what I expected.

There are a lot of small bugs in your code.
I added what I did in the comments
Please read the compiler messages carefully, when trying to solve bugs.
The contain the line number, the bug is on.
And most of the time usefull information about the problem on that line.
Use brackets to make your code more readable and less buggy.

Please notice that in case 2 :
The equation is not the way to check for even and odd
