The correct answer is: B. Dim dblAmounts(5) As Double<\/strong><\/p>\n A one-dimensional array is an array that has only one dimension. In other words, it is a list of items that are all of the same type. The number of items in a one-dimensional array is called the size of the array.<\/p>\n The syntax for declaring a one-dimensional array in Visual Basic is:<\/p>\n where:<\/p>\n In option A, In option B, In option C, In option D, Therefore, the correct answer is option B.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Dim dblAmounts(4) As Double” option2=”Dim dblAmounts(5) As Double” option3=”Dim dblAmounts(4) As Double = {3.55, 6.70, 8, 4, 2.34}” option4=”Dim dblAmounts() As Double={3.55, 6.70, 8, 4, 2.34,1.45}” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[731],"tags":[],"class_list":["post-48560","post","type-post","status-publish","format-standard","hentry","category-visual-basic","no-featured-image-padding"],"yoast_head":"\nDim arrayName(size) As type<\/code><\/p>\n\n

However, the size of the array is not specified. This means that the array will have a variable size, and it will be able to store any number of items. This is not a good practice, as it can make your code difficult to read and understand.<\/p>\n
