#include<stdio.h>
main()
{
int i=1;
printf("\n%d%d, i<<=1%2);
return 0;
}
In the above program the output is 2 as expected .
now since
#include<stdio.h>
main()
{
int i=1;
printf("\n%d%d ",i<<=2,i<<=1%2);
return 0;
}
Now since we are introducing an another statement which modifies i in the
same line , the previous value of i gets affected and changes to the new
value provided by the first i<<=2
So above o/p will be 8 8
though i<<=1%2 is 2 initially
it gets affected by i<<=2 and so value changes to 8 of both i's
Hope this is clear ...
