C++ compile time polymorphism doubt ?
- by user313921
Below program contains two show() functions in parent and child classes, but first show() function takes FLOAT argument and second show() function takes INT argument.
.If I call show(10.1234) function by passing float argument, it should call class A's show(float a) function , but it calls class B's show(int b).
#include<iostream>
using namespace std;
class A{
float a;
public:
void show(float a)
{
this->a = a;
cout<<"\n A's show() function called : "<<this->a<<endl;
}
};
class B : public A{
int b;
public:
void show(int b)
{
this->b = b;
cout<<"\n B's show() function called : "<<this->b<<endl;
}
};
int main()
{
float i=10.1234;
B Bobject;
Bobject.show((float) i);
return 0;
}
Output:
B's show() function called : 10
Expected output:
A's show() function called : 10.1234
Why g++ compiler chosen wrong show() function i.e class B's show(int b) function ?
