In today's world, where we spend a significant amount of our time indoors, the quality of the air we breathe inside our homes and workplaces is crucial for our health and well-being. Poor indoor air quality (IAQ) can lead to various health issues, including allergies, respiratory problems, and even long-term conditions. This blog post explores effective strategies for managing and improving indoor air quality. Understanding Indoor Air Pollutants Indoor air pollutants can originate from various sources: Biological Pollutants: Mold, dust mites, and pet dander. Chemical Pollutants: Volatile organic compounds (VOCs) from paints, cleaners, and furnishings. Particulate Matter: Dust, pollen, and smoke particles. Strategies for Improving Indoor Air Quality Ventilation: Natural Ventilation: Open windows and doors regularly to allow fresh air circulation. Mechanical Ventilation: Use exhaust fans in kitchens and bathrooms to remove pollutants directly at the source. Air Purifiers: HEPA Filt
INTRODUCTION
The programming language ‘C’ was developed by Dennis Ritchie in the early 1970s at Bell Laboratories. Although C was first developed for writing system software, today it has become such a famous language that a various of software programs are written using this language. The main advantage of using C for programming is that it can be easily used on different types of computers. Many other programming languages such as C++ and Java are also based on C which means that you will be able to learn them easily in the future. Today, C is mostly used with the UNIX operating system.
Structure of a C program
A C program contains one or more functions, where a function is defined as a group of statements that perform a well-defined task.The program defines the structure of a C program. The statements in a function are written in a logical series to perform a particular task. The most important function is the main() function and is a part of every C program. Rather, the execution of a C program starts with this function. From the structure given below, we can conclude that a C program can have any number of functions depending on the tasks that have to be performed, and each function can have any number of statements arranged according to specific meaningful sequence.
Note that programmers can choose any function name for functions. It is not compulsory to write Function1, Function2, etc., with an exception that every program must contain one function that has its name as main().
