2.30.2.Ambiguous function call when data type casting from int to char and unsigned char

#include <iostream>

using namespace std;



char myfunc(unsigned char ch);

char myfunc(char ch);



int main()

{

  cout << myfunc('c'); // this calls myfunc(char)

  //cout << myfunc(88) << " "; // ambiguous



  return 0;

}



char myfunc(unsigned char ch)

{

  return ch-1;

}



char myfunc(char ch)

{

  return ch+1;

}
