  Converting a string to an int in C++ for handling cryptocurrency transactions is a common task. One way to do this is by using the stoi() function from the <string> library. Here's an example: ```cpp #include <iostream> #include <string> int main() { std::string str = "12345"; int num = std::stoi(str); std::cout << "Converted int: " << num << std::endl; return 0; } ``` This code will output "Converted int: 12345". Make sure to include the <string> and <iostream> headers and use the std namespace to access the stoi() function. Alternatively, you can also use the atoi() function from the <cstdlib> library to convert a string to an int. Here's an example: ```cpp #include <iostream> #include <cstdlib> int main() { std::string str = "12345"; int num = std::atoi(str.c_str()); std::cout << "Converted int: " << num << std::endl; return 0; } ``` Both methods will give you the desired result, so choose the one that you find more convenient or suitable for your specific use case.
