Question

I can’t find the problem. I am trying to use char as parameter for a class template:

#include <iostream>

using namespace std;

template <class Type1, class Type2> class myclass
{   
    Type1 i;
    Type2 j;
public:
    myclass(Type1 a, Type2 b) {i=a; j=b;}
    void show() { cout << i << ' ' << j << '\n'; }
};

void main()
{   
    myclass<int, double> ob1(10, 0.23);
    myclass<char, char *> ob2('X', Just show ");
    ob1.show();   
    ob2.show();
}

Answer 1

You are missing an opening quote before Just:

myclass<char, char *> ob2('X', Just show ");
//                             ^ 
// should be:
myclass<char, char *> ob2('X', "Just show");

Note though that you should use const char* when you want to allow passing string literals and that this has ownership issues. Preferrably use std::string instead.
