This article introduces the relevant knowledge of "what is the meaning of sizeof in c language". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. The internal expression of sizeof () does not participate in the real operation, and the operation value is calculated at compile time.

2. Even if there is an assignment expression written inside sizeof, it will not be done in practice. Sizeof will only look at the type of Operand and will not access the corresponding space.

Example

Int main () {int a = 10 political int b = sizeof (a = a + 1); printf ("% d% d\ n", a, b); / / 10 4return 0;} "what is the meaning of sizeof in language c". Thank you for reading.
