C++ provides a data structure,\u00a0the array<\/strong>, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.<\/p>\n

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.<\/p>\n

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.<\/p>\n

Declaring Arrays:<\/strong><\/p>\n

To declare an array in C++, the programmer specifies the type of the elements and the number of elements required by an array as follows:<\/p>\n

type arrayName [ arraySize];<\/em><\/p>\n

This is called a single-dimension array. The\u00a0arraySize<\/strong>\u00a0must be an integer constant greater than zero and\u00a0type<\/strong>\u00a0can be any valid C++ data type. For example, to declare a 10-element array called balance of type double, use this statement:<\/p>\n

double balance[10];<\/em><\/p>\n

Initializing Arrays:<\/p>\n

You can initialize C++ array elements either one by one or using a single statement as follows:<\/p>\n

double balance[5] = {1000.0, 2.0, 3.4, 17.0, 50.0};<\/em><\/p>\n

The number of values between braces { } cannot be larger than the number of elements that we declare for the array between square brackets [ ]. Following is an example to assign a single element of the array:<\/p>\n

If you omit the size of the array, an array just big enough to hold the initialization is created. Therefore, if you write:<\/p>\n

double balance[] = {1000.0, 2.0, 3.4, 17.0, 50.0};<\/em><\/p>\n

You will create exactly the same array as you did in the previous example.<\/p>\n\n\n\n\n\n\n\n

Concept<\/th>\n	Description<\/th>\n<\/tr>\n
Multi-dimensional arrays<\/a><\/td>\n	C++ supports multidimensional arrays. The simplest form of the multidimensional array is the two-dimensional array.<\/td>\n<\/tr>\n
Pointer to an array<\/a><\/td>\n	You can generate a pointer to the first element of an array by simply specifying the array name, without any index.<\/td>\n<\/tr>\n
Passing arrays to functions<\/a><\/td>\n	You can pass to the function a pointer to an array by specifying the array’s name without an index.<\/td>\n<\/tr>\n
Return array from functions<\/a><\/td>\n	C++ allows a function to return an array.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n -The Admin.<\/p>\n  <\/p>\n <\/a> <\/p>\n","protected":false},"excerpt":{"rendered":" C++ provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type.
