const data members must be initialized using Initializer List. In the following example, “t” is a const data member of Test class and is initialized using Initializer List.
#include<iostream>
using namespace std;
class Test {
const int t;
public:
Test(int t):t(t) {} //Initializer list must be used
int getT() { return t; }
};
int main() {
Test t1(10);
cout<<t1.getT();
return 0;
}
/* OUTPUT:
10
*/
