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
DECLARATION OF ARRAYS
We have already seen that every variable must be declared before it is used. The same concept holds true for array variables. An array must be declared before being used. Declaring an array
means specifying the following:
* Data type—the kind of values it can store, for example, int, char, float, double.
* Name—to identify the array.
* Size—the maximum number of values that the array can hold.
Arrays are declared using the following syntax:
type name[size];
The type can be either int, float, double, char, or any other valid data type. The number within brackets indicates the size of the array, i.e., the maximum number of elements that can be stored in the array. For example, if we write,
int marks[10];
then the statement declares marks to be an array containing 10 elements. In C, the array index starts from zero. The first element will be stored in marks[0], second element in marks[1], and so on. Therefore, the last element, that is the 10th element, will be stored in marks[9]. Note that
0, 1, 2, 3 written within square brackets are the subscripts. In the memory, the array will be stored as shown in Fig
