    Need some more help this time with Pointer help

    k so im working on putting the value (what is being pointed to) from a pointer and adding
    it to the end of a string.

    Code:
    STRING& STRING::operator+=(char* c)
    {
        char* Temp = new char [Len+1];
        for (unsigned I= 0; I <Len; I++){
            Temp [I]= STR[I];
        }
        Len+=1;
        
        Temp[Len]=char(c); // this is where im trying to add the pointer
        
        delete [] STR;
        STR = Temp;
        return *this;
    }

    If this is the overload that only adds a single character, then you need to change your code:

    Code:
    STRING& STRING::operator+=(char* c) // Remove part in red
    {
        char* Temp = new char [Len+1];
        for (unsigned I= 0; I <Len; I++){
            Temp [i]= STR[i];
        }
        Len+=1;
        
        Temp[Len]=char(c); // this is where im trying to add the pointer
        
        delete [] STR;
        STR = Temp;
        return *this;
    }
    "What's up, Doc?"
    "'Up' is a relative concept. It has no intrinsic value."
