    Cool strings and char[]

    Hi there!!!!!!!!,

    I have two c type char arrays that I want to add together (with a space in between) and put into a cpp string. I am assuming da dis is the best way 2 do it.

    eg)

    Code:
    char n1[10] = "Bill";
    char n2[10] = "Stone"
    string str = n2 + " " + n1;
    I appreciate that stirng can be added but not like this.

    Anyone have any ideas for me plz?

    Thanks!!!

    Use the strcat function.

    Or you can use:
    sprintf(fullbuffer, "%s %s", n2, n1);
    Just make sure you have a big enough buffer.

    Or, if you want to actually use C++ style strings from C style array strings:
    Code:
    string str = string(n1) + " " + string(n2);

    Code:
    stringstream strs << n1 << " " << n2;
    string str = strs.str();

    Brilliant!!!!!!!!!!!!!!!!

    Would that be classed as type casting the char *'s??????

    That would be creating a temporary string out of a char* using the respective constructor.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
