3 Overloads Have Similar Conversions
Hi everyone,
I overloaded the addition operator for pointer notation in my assignment and I keep getting this error when I compile:
3 overloads have similar conversions
could be 'char *operator +(int,const String &)'
or 'String operator +(char,String &)'
or 'String operator +(const String &,const String &)'
while trying to match the argument list '(int, String)'
note: qualification adjustment (const/volatile) may be causing the ambiguity
It is happening at this part of the code:
Code:
void test15() {
cout << "15. Testing S15: Pointer notation." << endl << endl;
csis << "15. Testing S15: Pointer notation." << endl << endl;
String s15("ABCDE");
for(int i = 0; i < s15.getLength(); i++)
++(*(s15+i));
for (int j = 0; j < s15.getLength(); j++) {
cout << *(j + s15);
csis << *(j + s15);
}
cout << endl;
csis << endl;
wait();
}
And these are my overloaded operators...
I believe this is the one it should be using for the pointer notation in this case:
Code:
char* operator+(int index, const String& str){
char* value;
value = new char[1];
value[0] = str.buf[index];
return value;
}
Code:
char* operator+(const String& str, int index){
char* value;
value = new char[1];
value[0] = str.buf[index];
return value;
}
The following one isn't even supposed to be used for pointer notation, but it came up in the error...
Code:
String operator+(char a, String& str){
int len = str.length;
int count = 0;
char* temp;
temp = new char[len];
for(int i = 0; i < str.length; i++){
temp[i] = str.buf[i];
count++;
}
temp[count + 1] = a;
return temp;
}
So this means that the compiler doesn't know which one to use right? Did I overload them incorrectly?
Thanks for any help!
