How to use to_string In C++

 In C++, use std::to string to convert a double to a string. The required parameter is a double value, and a string object containing the double value as a sequence of characters is returned.

C++




// C++ Program to demonstrate Double to
// String Conversion using to_string
  
#include <iostream>
#include <string.h>
using namespace std;
  
int main()
{
  
    double n = 456321.7651234;
    string str = to_string(n);
    cout << "String is: " << str;
    return 0;
}


Output

String is: 456321.765123

C++ Program For Double to String Conversion

Here, we will build a C++ program for double to string conversion using various methods i.e.

  1. Using to_string
  2. Using stringstream
  3. Using sprintf
  4. Using lexical_cast

We will keep the same input in all the mentioned approaches and get an output accordingly.

Input:

n = 456321.7651234 

Output: 

string: 456321.7651234
