    you could increment your string and place all individually indexed location of the string into each individual location of the character array. you could do it with one loop, a string, and a char array. i unfortunatly do not recall any premade function to do this instantly.

    The string class contains a function that returns the string as a character array:

    Code:
    string c="Hello";
    strcat(a, c.c_str());   // the character array a will now contain "Hello"

    Code:
    #include <iostream>
    #include <cstring>
    #include <string>
    
    int main()
    {
        std::string str1 = "Hello";
        char str2[str1.length() + 1];
        //we can't just use length that would result in not null terminating 
        std::strcpy(str2,str1.c_str());
        
        std::cout<<"str1.length() = "<<str1.length()<<std::endl;//here is proof :)
        std::cout<<"str1 = "<<str1<<std::endl;
        std::cout<<"str2 = "<<str2<<std::endl;
        
        std::cin.get();
        return 0;
    }
    Woop?
