to_string c++
// to_string example
#include <iostream> // std::cout
#include <string> // std::string, std::to_string
int main ()
{
std::string pi = "pi is " + std::to_string(3.1415926);
std::string perfect = std::to_string(1+2+4+7+14) + " is a perfect number";
std::cout << pi << '\n';
std::cout << perfect << '\n';
return 0;
}Converting to string c++
- Writing your own conversion function, the simple:
template<class T> string toString(const T& x) {
ostringstream ss;
ss << x;
return ss.str();
}
- Since C++11 you can also use the std::to_string:
string s = to_string(0x12f3); // after this the string s contains "4851"how to convert int to string c++
#include <iostream>
#include <boost/lexical_cast.hpp>
using namespace std;
int main()
{
int i=11;
string str = boost::lexical_cast<string>(i);
cout<<"string value of integer i is :"<<str<<"\n";
