C++ 使用stringstream进行字符串与数字的转换

// using stringstream constructors.
#include <iostream>
#include <sstream>
using namespace std;
int main ()
{
int a;float b;long c;
char d[10],e[10],f[10];

/* string to number */
stringstream ss;
ss << "32";
ss >> a;
ss.clear();

ss << "3.1415";
ss >> b;
ss.clear();

ss << "567283";
ss >> c;
ss.clear();

cout<<a<<","<<b<<","<<c<<endl;

/* number to string */
ss << a;
ss >> d;
ss.clear();

ss << b;
ss >> e;
ss.clear();

ss << c;
ss >> f;
ss.clear();

cout<<d<<","<<e<<","<<f<<endl;

return 0;
}

Output:
32,3.141500,567283
32,3.141500,567283
