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

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
