In C programming, when declaring a variable, you typically start by specifying its data type followed by the variable name and, optionally, an initial value. For example, int a = 1; declares an integer variable named "a" with an initial value of 1.
This approach works well when dealing with a small number of variables. However, when you need to work with a large number of variables, it can become cumbersome to declare each one individually. This is where arrays come in handy. An array is a container that can hold multiple values of the same data type. To declare an array, you specify the data type, followed by the array name and its size in square brackets. For example, int ar[5000]; declares an array named "ar" capable of holding 5000 integers.
The way arrays work is that they only declare the first element, and the other elements are located in adjacent memory locations. In example, if the first element of the array is stored at memory location 410 bytes, the next element will be at 414 bytes, with a 4-byte gap, assuming each element is an integer. This contiguous memory arrangement allows for efficient access and manipulation of array elements.
