GlobalLogic Interview

 Toplevel traversal in a BST Class with parent virtual function defined (program) Virtual destructor copy constructor, copy constructor why do we give reference Polymorphism Frequency of characters in "globallogic" If we declare a constructor as private, can we create an object ? Ans: we can't create object on stack but we can create on heap using new  Even or odd using Thread coding question #include <thread> #include <iostream> using namespace std; void even_func(int n) {     if(n%2 == 0)     {         cout << "Number is even" <<endl;     }      } void odd_func(int n) {     if(n%2 != 0)     {         cout << "Number is odd" <<endl;     }      } int main() {      for(int i=0; i< 100; i++)      {         thread th1(even_func, i);         thre...

Euronet interview questions

Some questions were from test4geeks  void GetSomeVariable(int **i) {    if(*i == NULL)    {       *i = new int;    }   **i = 20;   } int main() {    int someValue = 10;    GetSomeVariable(&someValue);    cout << someValue <<endl;        int *ptr = nullptr;    GetSomeVariable(&ptr);    cout << *ptr <<endl; } How to make the code compilable without changing GetSomeVariable? Solution: Use Function overloading or Type traits #include <iostream> #include <type_traits> void g(int*) { std::cout << 'L'; } void g(int**) { std::cout << 'R'; } template<typename T> void f(T t) {     if (std::is_same_v<T, int>) { std::cout << 1; }      if (std::is_same_v<T, int*>) { std::cout << 2; }      if (std::is_same_v<T, int**>) { std::cout <...
