  • Ans. 

    Union in C++ is a data structure that allows storing different data types in the same memory location.

    • Unions are similar to structures but all members share the same memory location.

    • Only one member of a union can be accessed at a time.

    • Unions are useful when you need to store different data types in the same memory space.

    • Example: union MyUnion { int i; float f; };

    • Example: MyUnion u; u.i = 10; // Accessing integer member

  • Q3. What is weak pointer
  • Ans. 

    Weak pointer is a type of smart pointer in C++ that does not control the lifetime of the object it points to.

    • Weak pointers are used to break circular references in shared pointers.

    • They do not increase the reference count of the object.

    • They are used in scenarios where the object may be deleted while there are still weak pointers pointing to it.

  • Q2. Find the voltage through the resistor
  • Ans. 

    To find the voltage through a resistor, use Ohm's Law: V = I * R

    • Use Ohm's Law: V = I * R, where V is the voltage, I is the current flowing through the resistor, and R is the resistance of the resistor

    • If the current flowing through the resistor is 2A and the resistance is 5 ohms, the voltage would be V = 2 * 5 = 10V

    • Make sure to use the correct units for current (Amps) and resistance (Ohms) to get the voltage in Volts
