Now it is time to enable OpenMP support and disable optimization for both projects. Right click on project "Part ONE" in ''Solution Explorer'' and select ''Properties'' (Shortcut Alt + Enter when project "Part ONE" is selected). In ''Part ONE Property Pages'' dialog, expand ''Configuration Properties'' and select ''Language [Intel C++]'' sub-section under ''C/C++'' section (In the leftmost window), then enable OpenMP support by selecting ''Generate parallel Code (/Qopenmp)'' from ''OpenMP Support'' dropdown. Next, select Optimization sub-section under ''C/C++'' section, and disable optimization by selecting ''Disabled (/Od)'' from ''Optimization'' dropdown. Finally, enable OpenMP support and disable optimization for project "Part TWO" as we just did for project "Part ONE".

'''NOTE:''' Since we will be referring to the specific lines of code by its line numbers, it is important you enable line numbers in your Visual Studio (If it's not enabled already). To enable line numbers, select ''TOOLS > Options...'', then in ''Options'' dialog expand ''Text Editor'' section and select ''All Languages'' sub-section in the leftmost window. On the right side you will see ''Line Numbers'' as one of the checkboxes. Ensure that it is checked and click ''OK''.
