Width Specifier 2 C Programming From Problem Analysis

Width Specifier 2 C# Programming: From Problem Analysis to Program Design 4 th Edition 1

Width Specifier • Useful when you want to control the alignment of items on multiple lines • Alignment component goes after the index ordinal followed by a comma (before the colon) – If alignment number is less than actual size, it is ignored – If alignment number is greater, pads with white space • Negative alignment component places spaces on right Console. Write. Line("{0, 10: F 0}{1, 8: C}", 9, 14); 9 $14. 00 //Right justifies values C# Programming: From Problem Analysis to Program Design 2
