Fixed arrays

Fixed arrays refer to arrays that have a pre-determined size mentioned at declaration. Examples of fixed arrays are as follows:

int[5] age ; // array of int with 5 fixed storage space allocatedbyte[4] flags ; // array of byte with 4 fixed storage space allocated

Fixed arrays cannot be initialized using the new keyword. They can only be initialized inline, as shown in the following code:

int[5] age = [int(10), 20,30,40,50] ;

They can also be initialized inline within a function later, as follows:

int[5] age ;age = [int(10),2,3,4,5];
