stringstream用法 https://www.acwing.com/blog/content/5756/
#include <iostream>
#include <sstream>
using namespace std;
int main() {
stringstream ss;
ss << "string" <<" stream";
cout << ss.str();
ss.str("");
ss << "another string";
cout << ss.str();
return 0;
}
#include <iostream>
#include <sstream>
#include <string>
using namespace std;
int main() {
string src("Avatar 123 5.2 Titanic Kv");
istringstream istrStream(src); // 建立src到istrStream的联系
string s1,s2;
int n;
double d;
char c;
istrStream >> s1 >> n >> d >> s2 >> c; // 把src的内容当做输入流进行读取
ostringstream ostrStream;
ostrStream << s1 << endl << s2 << endl << n << endl << d << endl << c <<endl;
cout << ostrStream.str();
return 0;
}
程序的输出结果:
Avatar
Titanic
123
5.2

string str = "89";
int i = stoi(str);
cout << i;
