It depends upon the variable type. Ex: if the variable is
declared as unsigned int then if we increment the value will
not become negative.

Answer / sachin
after a limit of the variable ,it becomes -ve.
for ex:-
#include<stdio.h>
void main()
int i;
if(i<=32767)
{
printf("%d",i);
i++;
}
}after printing 1 to 32767,it tries to become 32768 which is
outside the limit,so it goes to the other side and become
-32768 and loops become indefinite.
