有如下程序： #include＜iostream＞ using namespace std; int fun(int a, int b) {return(++a*b++);} void main() { int x=3,y=4,z=5,r; r=fun (fun (x,y),z); cout＜＜r＞＞endl; cout＜＜x＜＜endl; cout＜＜y＜＜endl; } 该程序的输出的结果是( )。
A．85 3 4
B．60 3 4
C．126 4 5
D．85 4 5
参考答案：A
解析： 注意运算符“++”在变量前与后的区别；fun()函数采用值传递的方式，所以调用前后x和y的值不会发生变化。
