c debugging boolean variable-assignment unsigned

Why doesn't "a && (b = 5/a)" assign "5/a" to "b"?

Does a && (b = 5/a) assign 5/a to b (for nonzero a)?

My friend says it doesn't, but I'm confused why it wouldn't.

Solution

Your friend is wrong. For nonzero a, the statement a && (b = 5/a) will assign the value 5/a to b.

If a == 0, then the conditional will short circuit and the assignment will not occur.
