Removing Precompiler Secure Warnings by Default in Visual Studio

In Visual Studio, when working with functions like scanf(), developers often encounter precompiler secure warnings. To disable these warnings, a common practice is to add a line to project options or include #define _CRT_SECURE_NO_WARNINGS at the start of the code. However, this approach can be tedious when creating multiple projects.

To resolve this issue, Visual Studio provides a way to set preprocessor secure warnings as NO_WARNINGS by default for all projects. By following these steps, developers can avoid the need for repetitive configurations:

1. In Solution Explorer, select all desired projects.
2. Press Alt F7 or right-click and choose "Properties."
3. Under "Configurations," select "All Configurations."
4. Click on "Preprocessor Definitions."
5. Choose "Edit" from the dropdown menu.
6. Copy "_CRT_SECURE_NO_WARNINGS" into the "Preprocessor Definitions" text box.
7. Save the changes.

By completing these steps, all projects in the solution will have precompiler secure warnings turned off, eliminating the need for manual configuration. This simplified process ensures a more efficient workflow for developers, especially when working with numerous projects.
