}
int main(int argc, const char * argv[]) {
// insert code here...
Example obj1(10),obj2(20);
cout<<"Address of objects are "<<&obj1<<" and "<<&obj2<<endl;
obj1.printAddressAndValue();
obj2.printAddressAndValue();
return 0;
}
运行结果
Address of objects are 0x7ffeefbff578 and 0x7ffeefbff570
The object at address 0x7ffeefbff578 has value 10
The object at address 0x7ffeefbff570 has value 20
Program ended with exit code: 0
