  When it comes to converting a string to an int in C++ for cryptocurrency data, you can also consider using the std::stoll function. This function is similar to std::stoi, but it converts the string to a long long int instead of a regular int. Cryptocurrency data can sometimes involve large numbers, so using std::stoll ensures that you don't encounter any overflow issues. Here's an example: ```cpp #include <iostream> #include <string> int main() { std::string str = "12345678901234567890"; long long int num = std::stoll(str); std::cout << "Converted integer: " << num << std::endl; return 0; } ``` This will output: ``` Converted integer: 12345678901234567890 ``` Using std::stoll provides a reliable way to convert cryptocurrency data strings to integers, even when dealing with large numbers or potential overflow issues.
