Array elements values can be of any type. An array cannot be declared on the level of a client terminal, that is why global variables of client terminal cannot be gathered into an array. Accordingly, values of global array elements are available to the whole program, values of a local one - only to the function, in which it is declared. An array can be declared like a variable on the global and local level. Array Declaration and Access to Array ElementsД«efore using an array in a program, it must be declared. The row number is the first index value, the number of place in a raw is the value of the second index, viewers are array elements, viewer's surname is the value of an array element, cinema ticket (specifying row and place) is a method to access the value of an array element. The closest everyday analogue of a two-dimensional array is a cinema hall. The way of specifying indexes when each index is in square brackets is also acceptable: In MQL4 indexing starting form zero is used. Array element index is indicated after a variable identifier (array name) and is an integral part of an array element. Array element index uniquely defines place of an element in an array. IndexingДЄrray element index is one or several integer values indicated in the form of a constant, variable or expression enumerated comma-separated in square brackets. Graphical presentation of arrays of integer type: a) one-dimensional b) two-dimensional c) three-dimensional. Arrays ofДЄrray element is a part of an array it is an indexed variable having the same name and some value.ДЇig.

Maximum admissible amount of dimensions in an array is four. Arrays can be one-dimensional and multidimensional. Concept of ArraysДЄrray is an arranged set of values of one-type variables that have aД¬ommon name. A large part of information processed by application programs is contained in arrays.
