C++ Arrays

In C++, an array is a data structure that is used to store multiple values of similar data types in a contiguous memory location.

For example, if we have to store the marks of 4 or 5 students then we can easily store them by creating 5 different variables but what if we want to store marks of 100 students or say 500 students then it becomes very challenging to create that numbers of variable and manage them.

Now, arrays come into the picture that can do it easily by just creating an array of the required size.

Properties of Arrays in C++

An Array is a collection of data of the same data type, stored at a contiguous memory location.
Indexing of an array starts from 0.

It means the first element is stored at the 0th index, the second at 1st, and so on.
Elements of an array can be accessed using their indices.
Once an array is declared its size remains constant throughout the program.
An array can have multiple dimensions.
The size of the array in bytes can be determined by the sizeof operator using which we can also find the number of elements in the a
