main.cpp

对于c++primer中前面几章的练习以及书上的例子

#include <cstdlib>
#include <iostream>
#include<string>
#include<cstddef>
using namespace std;

int main(int argc, char *argv[])
{
    size_t ia;
    ia=sizeof(ia);
    ia=sizeof ia;
    ia=sizeof(int);
    int *pi=new int[12];
    cout<<"pi:"<<sizeof(pi)<<"*pi:"<<sizeof(*pi)<<endl;
    string st1("foobar");
    string st2("a maighty cak");
    string *ps=&st1;
    cout<<"st1"<<sizeof(st1)<<"st2:"<<sizeof(st2)<<"ps:"<<sizeof(ps)<<"*ps:"<<sizeof(*ps)<<endl;
    
    system("PAUSE");
    return EXIT_SUCCESS;
