`SIZE`

— Determine the size of an array ¶*Description*:Determine the extent of

`ARRAY`along a specified dimension`DIM`, or the total number of elements in`ARRAY`if`DIM`is absent.*Standard*:Fortran 90 and later, with

`KIND`argument Fortran 2003 and later*Class*:Inquiry function

*Syntax*:`RESULT = SIZE(ARRAY[, DIM [, KIND]])`

*Arguments*:`ARRAY`Shall be an array of any type. If `ARRAY`is a pointer it must be associated and allocatable arrays must be allocated.`DIM`(Optional) shall be a scalar of type `INTEGER`

and its value shall be in the range from 1 to n, where n equals the rank of`ARRAY`.`KIND`(Optional) A scalar `INTEGER`

constant expression indicating the kind parameter of the result.*Return value*:The return value is of type

`INTEGER`

and of kind`KIND`. If`KIND`is absent, the return value is of default integer kind.*Example*:PROGRAM test_size WRITE(*,*) SIZE((/ 1, 2 /)) ! 2 END PROGRAM
