Guys why this code wont run??

Question

I don't know why it wont run,i thought it's the way to send an int to another int
int x=10;
int y=11;
int x=int y;
Why it wont run it says it's wrong

Answer 1

The variables x and y are already defined, and redefining them into a shared scop will cause a "redifination" error.

int x =10;
int y = 11;
x =y;
