Arrays in C++ are one of the most important user-defined data types in C++. They can be used to store a large amount of data of the same data type sequentially. C++ also supports N-Dimensional arrays that can be used for problem-solving in scientific computing. For example, we can use the 2-Dimensional array of C++ to create a matrix, and they have wide usage in NLP, Machine Learning, and Artificial Intelligence.
