Noise pollution is a significant environmental issue, particularly in industrial settings. The constant hum of machinery, the clanging of metal, and the roar of engines contribute to a cacophony that can have serious health implications for workers and nearby residents. Addressing noise pollution in industries is not only a matter of regulatory compliance but also a crucial step in ensuring the well-being of employees and the community. Understanding Noise Pollution in Industries Industrial noise pollution stems from various sources such as heavy machinery, generators, compressors, and transportation vehicles. Prolonged exposure to high levels of noise can lead to hearing loss, stress, sleep disturbances, and cardiovascular problems. Beyond health impacts, noise pollution can also reduce productivity, increase error rates, and contribute to workplace accidents. Regulatory Framework Many countries have established regulations and standards to limit industrial noise. Organizations like t
FUNCTIONS
C enables its programmers to break up a program into segments commonly known as functions, each of which can be written more or less independently of the others. Every function in the program is supposed to perform a well-defined task. Therefore, the program code of one function
is completely insulated from the other functions.
Every function interfaces to the outside world in terms of how information is transferred to it and how results generated by the function are transmitted back from it. This interface is basically specified by the function name. For example, look
at below figure which explains how the main() function calls another function to perform a well-defined task.
In the figure, we can see that main() calls a function named func1(). Therefore, main() is known as the calling function and func1() is known as the called function. The moment the compiler
encounters a function call, the control jumps to the statements that are a part of the called function.
After the called function is executed, the control is returned to the calling program.
The main() function can call as many functions as it wants and as many times as it wants. For example, a function call placed within a for loop, while loop, or do–while loop may call the same function multiple times till the condition holds true.
Not only main(), any function can call any other function. For example, look at below figure which shows one function calling another, and the other function in turn calling some other function.
