Round 2 - One-on-one 

(2 Questions)

  • Q1. Why we should use auto keyword in local scope only
  • Ans. 

    Using auto keyword in local scope only ensures type safety and avoids unintended side effects.

    • Auto keyword deduces the type of the variable from its initializer expression.

    • Using auto in local scope avoids unintended type conversions and promotes type safety.

    • Auto keyword should not be used for function parameters or class members.

    • Example: auto x = 10; // x is deduced as int

    • Example: auto y = 3.14; // y is deduced as doub

  • Answered by AI
  • Q2. Why the default value of reg keyword is garbage value only
  • Ans. 

    The default value of reg keyword is garbage value due to performance optimization.

    • Garbage value is faster to assign than initializing to a specific value.

    • Initializing to a specific value would require additional instructions and memory access.

    • The value of reg keyword is expected to be overwritten before use.

    • Garbage value can help in detecting uninitialized variables during testing.

    • Example: int x; // x will have a garba
