Comma operators and assignment operators - return values

Question

The following code segment get an output of 32, I am kind of confusing why?

 int i=(j=4,k=8,l=16,m=32); printf(“%d”, i); 

Answer 1

Start reading inside the first set of parentheses.

The comma operator evaluates each of several expressions subsequently. It returns the return value of the last expression - in this case, it is 32, because the return value of an assignment is the value assigned.
