value range of the data that can be stored is (Binary) 0000 0000-> (Binary) 1111 1111, or (decimal) 0-> (decimal) 255 If you want to add two numbers beyond this range, it will "overflow ". For example, in this storage, (decimal) 4 + (decimal) 254 =? From the binary perspective: (Binary) 0000 0100 = (decimal) 4 (Binary) 1111 1110 = (decimal) 254 ------------------------------------- + (Binary) 1 0000 0010 =

commands and variables:FOR/parameter % variable IN (set) DO command [command_parameters] % variable: specify a parameter that can be replaced by a single letter, FOR example, % I, and specify a variable: % I, which is case sensitive (% I is not equal to % I ).Each batch processing can process 10 variables from % 0-% 9, of which % 0 is used by default for batch file names, % 1 is the first value input when this batch is used by default. Similarly, % 2-% 9 indicates the input value 2-9. For examp

storyboard to disable automatic layouts. The dimensions are categorized as compatible with iOS 7 and newer systems.Drag three views into the main view and arrange:For easy identification, set different colors for each view.Each view is embedded (inset) in the window (Windows), 20 points from the edge. The spacing between views is also 20 points. The bottom view has a width of 280 points, and the top two views are 130 points wide. All view heights are 254
