Seriously, as Ace explained, they're used to index the 2D array.

int n=3;
This declares a variable called n of int type and assigns it a value of 3 (initialization).
int i,j;
Creates two variables of int type (no initialization).
Sooo:
int n=3,i,j;
Does all the above!

Answer 3

int n=3,i,j;
What is it???

I can not understand what program you wanted to write
