why wont this work

Question

#include <iostream>
using namespace std;

template <class T>
class Div {
public:
Div (T x, T y) {
cout <<x / y<<endl;
}
};

template < >
class MyClass<char> {
public:
MyClass (char x) {
cout << x <<endl;
}
};

int main () {
string a, b;
cin >> a >> b;
int x, y;
cin >> x >> y;

Div <string> d2(a, b);
Div <int> d1(x, y);

}

Answer 1

Mando

Because that is not a right template. You have to make template of Div class. My class doesn't not exist.

Check this line:

Div <string> d2(a, b);

And also you have to calculate division of length of string x and y where x is a and y is b

template < >
class Div<string> {
public:
Div (string x, string y) {
cout << x.size() / y.size() <<endl;
}
};

Answer 2

#include <iostream>
using namespace std;

template <class T>
class Div {
public:
Div (T x, T y) {
cout<<x / y<<endl;
}
};

template <class T>
class MyClass {
public:
MyClass (char x) {
cout << x <<endl;
}
};

int main () {
char a, b;
cin >> a >> b;
int x, y;
cin >> x >> y;

Div <char> d2(a, b);
Div <int> d1(x, y);
MyClass <char> mC(a);
}
