Answer 1

You can put semicolon (empty statement) at the end of case statement (right after colon), like this:
case 1: ;
int num;
.....
.....
case 2: ;
...

Or, better, move all variable declaration outside of the switch.
Put it before switch statement

int num;
int r;
int n;
char word[8];
switch(j)
{
.....

Declare variable before switch statement
