What will be the output of the following program?

#include<iostream.h> 
class AptitudeCrack
{
    int K; 
    public:
    void AptitudeFunction(float, int , char);
    void AptitudeFunction(float, char, char);
    
};
int main()
{
    AptitudeCrack objIB;
    objIB.AptitudeFunction(15.09, 'A', char('A' + 'A'));
    return 0;
}
void AptitudeCrack::AptitudeFunction(float, char y, char z)
{
    K = int(z);
    K = int(y);
    K = y + z;
    cout<< 'K = ' << K << endl; 
}
