Struct with Array Elements

To access elements in an array that is within a struct, use a dot operator followed by a subscript operator. The dot operator first accesses the specified array element in a struct. Then, the subscript operator accesses elements in the array based on the index value.

For example, you have the following struct with the array elements

drinks, sandwiches,

and

salads

menu_struct{
drinks: ['milk','coffee','tea','chai']
sandwiches: ['ham','turkey',NULL]
salads: ['caesar','cobb','greek','chipotle']
}

When you use the expression

menu_struct.drinks[0]

, the dot operator first accesses the array element

drinks

. Then, the subscript operator accesses the element at position 0 in the array

drinks: ['milk','coffee','tea','chai']

. The return value is

milk

The following expressions use a dot operator followed by a subscript operator to access elements from the arrays in the struct

menu_struct

Input Value	RETURN VALUE
menu_struct.drinks[1]	'coffee'
menu_struct.sandwiches[2]	NULL
menu_struct.salads[3]	'chipotle'
menu_struct.drinks[0,3]	['milk','coffee','tea']
