The -warnaserror+ option treats all warnings as errors
Syntax
-warnaserror[+|-][:warning-list]
Remarks
Any messages that would ordinarily be reported as warnings are instead reported as errors, and the build process is halted (no output files are built).
By default, -warnaserror- is in effect, which causes warnings to not prevent the generation of an output file. -warnaserror, which is the same as -warnaserror+, causes warnings to be treated as errors.
Optionally, if you want only a few specific warnings to be treated as errors, you may specify a comma-separated list of warning numbers to treat as errors.
Use -warn to specify the level of warnings that you want the compiler to display. Use -nowarn to disable certain warnings.
To set this compiler option in the Visual Studio development environment

3.Modify the "Warnings As Errors" property.
