Nettet26. sep. 2010 · a=6，b=16 这题没什么难度，主要是看先加和后加，首先可以确定的是，不管先加还是后加，a的值都会加到6，所以两次a都等于6，对于b，第一次是a是后加，所以b的值等于3+3+3（9），第二次a的值先加等于6+5+4（16）。 Nettet7. jul. 2015 · int b = a++;他的详细过程是 先将a现有的值赋值给b，然后对a进行自加操作a+=1; 完整的列出来给你看下 int b = a++; 相当于下面两步 int b =a; a+=1; 顺便提一下++a;++a的计算过程是，先计算a+=1，然后将a的值赋值给b 相当于: a+=1; int b=a; 次序正好与上面相反，但是无论哪个，最后a的值都是变化的。 如果你想要a不变化，就这样 … mill creek sports complex millbrook al
