C++ 对象参数传递
#include<iostream.h>class Test{public: int month;};/*副本传递对象，副本对象的属性改变了，但原来的没有改变，语法和java一样，但实际的效果不一样 */void changeObject(Test t){t.month=3;}void changeObjectII(Test & t){t.month=4;}void changeObjectIII(Test * t){t->month=5;}void main(){ Test t; t.month=1; changeObject(t); /*引用传递和指针传递都会改变对象的属性 */ cout << t.month; changeObjectII(t); cout << t.month; changeObjectIII(&t); cout << t.month;}1 , 4, 5
