PAVITHRAN T ECEMar 28, 2024 · 2 years ago1 answers

I am working on a cryptocurrency application in C++ and I need to convert a string to a number. How can I achieve this in C++? Specifically, I want to convert a string representation of a cryptocurrency value, such as '0.001 BTC', into a numerical value that I can use for calculations. Can anyone provide me with a code snippet or guide me on how to accomplish this?

    Hey there! Converting a string to a number in C++ for cryptocurrency applications is a breeze. You can use the 'std::stod' function from the 'string' library. Here's a code snippet to get you started: ```cpp #include <iostream> #include <string> int main() { std::string str = "0.001 BTC"; double number = std::stod(str); std::cout << "Converted number: " << number << std::endl; return 0; } ``` This code snippet will convert the string '0.001 BTC' into the numerical value 0.001. Just make sure to include the 'string' and 'iostream' libraries in your code.
