Question 5 The description of _______ can be given by a lexical specification, which is usually separate from the syntactic description of the language. The ___________ of a programming language include its numeric literals, operators, and special words, among others. One can think of programs as strings of rather than of characters. (One word, all the blanks would fit the one word, plural)

9. Represent the following statements using syntax in C programming language. S = n k = n while (k > 1) k = k - 1 s = s + k
Most programming languages currently adopt Algol60's free structure, where statements can begin anywhere but must conclude with an explicit end symbol, such as a semicolon. Unlike other languages, Python has a fixed format where statements start in a column and stop at the end of the line unless continuation marks are specified. The impact of format on readability, writability, and security.
