字符char、字符串string、整数int之间的转换

#include <iostream>
#include <string>
#include <sstream>

using namespace std ;

void i2s(int x, string &basic_string) {
    stringstream ss;
    ss << x;
    ss >> basic_string;
}

void s2i(string &basic_string , int &x ) {
    stringstream ss;
    ss << basic_string;
    ss >> x;
}

void c2s(char c , string & s){
	stringstream stream;
	stream << c;
	s = stream.str();
}

int main(){

	string str = "123";
	int  c ;

	s2i(str , c);

	cout << c ;
}
