Clang is a compiler frontend for the LLVM compiler infrastructure, designed to be the successor to the GNU Compiler Collection (GCC). It is open-source software developed by the LLVM Project, released under the University of Illinois/NCSA Open Source License. Clang is similar to, and supports most of the same language features as GCC, but it adds advanced features such as a modular code generator, advanced type-checking and many diagnostics including static analysis. Clang is also used as the primary compiler for Apple's operating systems and development tools, including Mac OS X, iOS, and the OpenCL language.
If you're using a laptop, you can use the Function + F keys in combination with your laptop's brightness settings to control the brightness. On a desktop computer, you can usually control brightness through the system settings, either in the Control Panel or in the Windows Settings app. You can also use the Windows Mobility Center to control brightness settings in laptops.Most laptops have a special key combination that you can press to turn on the keyboard backlight. On some laptops, the Fn or Function key is combined with the space bar, F6, or another key. You may have to check your laptop's manual to find the exact key combination. If you can’t find the manual, you can also usually find it online. Once you have located the key combination, use it to turn on the keyboard backlight.Depending on the model of your computer, there are various ways in which you can change the light. Many modern computers feature customizable lighting, allowing you to select the color, intensity, and brightness of the lights. There will typically be a dedicated control panel or utility to do this, which can be accessed either through the operating system or through the manufacturer's website.
In other cases, you may need to open up the computer case and physically adjust the lights or replace them. If you're not comfortable doing this yourself, you can always take the computer to a technician to get it done for you.1. Open the Settings app.
