How to Convert String to Double in C++

To convert a string to double in c++, we can use the stod() function by passing a string as an argument.

Here is an example that converts the string "90.556" to an double.

#include <iostream>
#include <string>

using namespace std;

int main() {
 string price = " 90.556 ";
 double result = stod(price);
 cout << "string (\"" << price << "\") is " << result << '\n';
}

Output:

string (" 90.556 ") is 90.556
