Nettet15. feb. 2012 · First of all, the Java Language Specification doesn't say anything about timing. But assuming we're using a typical compiler such as Suns javac we see that all of the above examples ( a++, ++a, a += 1, a = a + 1) could either be compiled into something like: iinc instruction, working on variables: Nettet11.对for(表达式1;;表达式3)可理解为(B) A for(表达式1;0;表达式3) B for(表达式1;1;表达式3) C for(表达式1;表达式1;表达式3) D for(表达式1表达式2;表达式3) 12.若i为整型变量,则以下循环执行的次数是(B) A3 2 1B2 1 0C3D2

Nettet7. aug. 2013 · It would seem that having a sequence point is immaterial in the expression b=++a + ++a; 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. NettetAccording to the C operator precedence, it is actually looks like: int a=2, b=3, c; c = (a++) + b; // 2+3=5 and 'a' will be 3 after that line printf ("%d\n",c); // c = 5 c = a + (b++); // …
