MOOC清华《面向对象程序设计》第2章：auto变量实验

#include <iostream>using namespace std;int main(){auto i = 3;auto f = 4.0f;cout << "i = " << i << endl;cout << "sizeof(i) = " << sizeof(i) << endl;cout << "sizeof(int) = " << sizeof(int) << endl << endl;cout << "f = " << f << endl;cout << "sizeof(f) = " << sizeof(f) << endl;cout << "sizeof(float) = " << sizeof(float) << endl;cout << "sizeof(double) = " << sizeof(double) << endl;return 0;}
