    Converting a string to an integer in C++ for cryptocurrency transactions can be done using the stoi() function. This function takes a string as input and returns the corresponding integer value. For example, you can use stoi("123") to convert the string "123" to the integer 123. Remember to handle any exceptions that may occur, such as invalid input or out-of-range values. Another option is to use the stringstream class. You can create a stringstream object, pass the string to it using the << operator, and then extract the integer using the >> operator. This method provides more flexibility and error handling options compared to stoi(). If you're working with larger numbers, you might need to use a different data type, such as long long int. In that case, you can use the stoll() function to convert the string to a long long integer. Choose the method that best suits your needs and make sure to handle any potential errors that may occur during the conversion process.
