  Another way to convert a string to an integer in C++11 for cryptocurrency applications is by using the atoi() function. This function takes a string as input and returns the corresponding integer value. However, it does not handle error checking, so you need to ensure that the string is a valid integer before using this function. Here's an example: ```cpp #include <iostream> #include <cstdlib> int main() { char str[] = "67890"; int num = std::atoi(str); std::cout << num << std::endl; return 0; } ``` This will also output 67890. In conclusion, there are multiple ways to convert a string to an integer in C++11 for cryptocurrency applications. You can choose the method that best suits your needs based on factors such as error handling and performance requirements.
