C String Concatenation

have the following code:

        char *doencode(const unsigned char *input, int length)
        {
        //irrelevant code
        }

        char *fname, *lname;
        char *encoded, *name;

        name = fname + "|" + lname;
        encoded = doencode(name, 30);

and I get this error: invalid operands to binary +

How can I combine fname & | & lname?

Answer 1

You cannot concatenate char* and char[] (the "|") or any permutation of using +. Use strncat() or snprintf() instead and ensure the destination buffer has enough memory to store the final string.
