Int a 5 b ++a c a++

Nettet29. mar. 2012 · int a = 10; int b = a++; In that case, a becomes 11 and b is set to 10. That's post-increment - you increment after use. If you change that line above to: int b = ++a; then a still becomes 11 but so does b. That's because it's pre-increment - you increment before use.

That is, whether the first ++a is evaluated first or the second ++a is evaluated first in either case a is incremented twice and then the + operator takes effect, so the eventual equation is either b = 2 + 3; or b = 3 + 2 thus b = 5. When I get home I will try this on with my C compiler.Nettet8. des. 2024 · @Saurabh P Bhandari, It's not UB. You might be thinking of a++ + a which is UB because it both reads from and writes to a. C uses the longest sequence that forms a token when tokenizing, so a+++b mans a++ + b, which is perfectly ok. –Nettet7. aug. 2024 · 所以，这个语句执行顺序是：. 先做 ++a， 这个时候a的值已经变成了1并且参与运算（就是先赋值，后参与运算）. 然后做 a++， a的值变成了2但是不参与运算（就是先参与运算，运算结束后赋值）. 然后在运算的时候，两个a参与运算的值都是1，b就是2了. 然 …churches savannah ga
