Input value to "Wire.begin()" using variable [SOLVED]

What variable type i need to declare, so i can use it to give pin numbers for "Wire.begin()" ?

Example code:

const char* wires = "0,2";

Wire.begin(wires);

Currently i get error: call of overloaded 'begin(const char*&)' is ambiguous

The input parameter for that function is a seven bit slave address. 0-127

Are you using an ESP8266? If so, the syntax for the begin function is:

Wire.begin(int sda, int scl);

The begin function does not take a string, but 2 numbers of the int data type.

You could do:

int sda = 0;
int scl = 1;

void setup()
{
Wire.begin(sda, scl);
...
}

This works for me. Thank You
