  If you prefer a more advanced and flexible approach, you can use the Boost library in C++. Boost provides a wide range of utility functions and classes, including a powerful string conversion library. Here's an example of converting a string to an integer using Boost: ```cpp #include <iostream> #include <string> #include <boost/lexical_cast.hpp> int main() { std::string str = "91011"; int num = boost::lexical_cast<int>(str); std::cout << "Converted integer: " << num << std::endl; return 0; } ``` In this code snippet, the lexical_cast function from the Boost library is used to convert the string "91011" to the integer 91011. This function automatically handles the conversion and throws an exception if the conversion fails. It is a powerful tool for string-to-integer conversion in C++.
