發現一個好用的string轉float float轉string的東西

#include<iostream>
#include<string>
#include<sstream>
using namespace std;
int main()
{
    stringstream ss;
    /*string s = "123.1";
    ss << s;
    float a;
    ss >> a;
    cout << a + 1;*/


    float b = 10.1;
    ss << b;
    string p;
    ss >> p;
    cout << p;

}
