declare an array in C++

  int array[10];

This code is declaring an array of integers in C++. The array is given the name “array” and is allocated 10 elements of memory. The elements that are created are all initialized as 0. An array is a data structure used to store a collection of elements, of the same data type, where each element is identified by its index position. In this case, the array holds 10 integers, indexed from 0 to 9. The square brackets after ‘array’ indicate the number of elements in the array, in this case 10. The ‘int’ before ‘array’ indicates the type of data stored in the array.
