c++ stringstream 实现字符串与int之间的转换

#include <iostream>
#include <sstream>
using namespace std;
int main()
{
    //string转int
    string str="10";
    int num;
    stringstream ss;
    ss<<str;
    ss>>num;
    cout<<num+1;
 
    ss.clear();//将读写状态重置
    ss.str("");//将内容置空
    
    //int转string
    int num2=100;
    string str2;
    ss<<num2;
    ss>>str2;
    str2[0]='d';
    cout<<str2;
}
