Or perhaps it's the other way around. Try the following experiment: A) write a short C # program that adds two integers. B) Look at the generated Il. C) do the same thing with two decimals. The difference is that decimal is implemented as a user-defined type, while types

array in a program, you must declare a variable that references an array and indicate the element type of the array. (unlike the declaration of a basic data type variable, declaring an array variable does not allocate any space to the array in memory.) It simply creates an array of references to the storage location).Java supports a for Loop, called a for-each Loop, that does not apply subscript variables that can sequentially traverse the entire array. For(double u:mylist){System.out.print (U

conventions. the first non-empty row string after the first line determines the amount of indentation for the entire document string. (We don't use the first line because it's usually close to the quotation marks at the beginning of the string and its indentation is not clear.) the spaces that are equal to the indentation at the beginning of all rows are filtered out. You should not indent fewer rows, but if they occur, all of their leading blanks should be removed. The length of the white s
