Study Notes

Arrays in C++

The purpose of an array in C++ is to store a collection of values of the same data type in a single variable.

Accessing Array Elements in C++

Elements in an array are accessed using an index, which starts from 0.

Array Size in C++

The maximum number of elements an array in C++ can hold depends on the amount of memory available.

File Handling in C++
