Warning Configurations in Compiler

We can configure the compiler to show warning diagnostics for the programs so that we can make the program better.

Provide the following flags to the compiler to configure warnings.

<compiler> \
    - Wall
    - Weffc++
    - Wextra
    - Wconversion
    - Wsign-conversion

• -Wconversion flag configures the compiler to issue warning for any lossy numeric conversion.
