What will be the output of the following C++ code?
#include <iostream>
using namespace std;
template<typename T>class clsTemplate
{
public:
T value;
clsTemplate(T i)
{
this->value = i;
}
void test()
{
cout << value << endl;
}
};
class clsChild : public clsTemplate<char>
{
public:
clsChild(): clsTemplate<char>( 0 )
{
}
clsChild(char c): clsTemplate<char>( c )
{
}
void test2()
{
test();
}
};
int main()
{
clsTemplate <int> a( 42 );
clsChild b( 'A' );
a.test();
b.test();
return 0;
}
#include <iostream>
using namespace std;
template<typename T>class clsTemplate
{
public:
T value;
clsTemplate(T i)
{
