    convert string to int

    I have this program where the user can enter commands, followed by either a string, or int, depends on which command asks for.

    so i store the input all into one string, then cut it into two strings command and input

    is there a simple way to convert a string of numbers into integers?

    Code:
    #include <sstream>
    #include <string>
    #include <iostream>
    
    int main()
    {
        std::string str = "123 456 789";
        std::stringstream sstr(str);
        int number;
    
        while( sstr >> number )
            std::cout << number << std::endl;
    
        return 0;
    }
    Output:
    Code:
    123
    456
    789
