  If you're working with digital currency transactions, it's important to handle the possibility of invalid input. You can use try-catch blocks to catch any exceptions that may occur during the conversion process. Here's an example: ``` #include <iostream> #include <string> int main() { std::string str = "123abc"; try { int num = std::stoi(str); std::cout << "The integer value is: " << num << std::endl; } catch (const std::invalid_argument& e) { std::cout << "Invalid input: " << e.what() << std::endl; } catch (const std::out_of_range& e) { std::cout << "Out of range: " << e.what() << std::endl; } return 0; } ``` This will output: ``` Invalid input: stoi ``` In this example, the string "123abc" cannot be converted to an integer, so an exception is thrown. The catch blocks handle the exceptions and provide appropriate error messages. I hope this helps! Let me know if you have any further questions.
