I need help with these questions, please write the answer and not "a" , "b", "c", or "d". Thanks.

1. Multiple Choice. Choose only one answer for each question. Choose the best answer if more than one answer is acceptable. 1.5 In contrast to Web 1.0, what is the key function of Web 2.0? Web is the computing platform Web supports graphic display Web supports semantic analysis Web is accessed over HTTP protocol 1.10 In the following pseudo code, which programming language allows the mixed use of data types? int i = 1; char c = 'a'; // declaration and initialization c = c + i; // execution of an assignment statement Ada Java All of them 1.11 In the layers of programming language structure, which layer performs type checking? lexical syntactic contextual semantic 1.12 How many different identifiers can the following BNF ruleset generate? ::= a b c ... 1 x y z :: = 0 26 more than 26 1.14 Which command (construct) has a loop when expressed in syntax graphs? if-else O switch for while 1.18 What is the difference between an inline function and a macro in C++? There is no difference between them. The inline functions are for Java only. There are no inline functions in C++. Inlining is a suggestion to the compiler, while a macro definition will be enforced. A macro definition is a suggestion to the compiler, while inlining will be enforced. 1.19 Macros-Processing takes place during which phase? Editing Preprocessing Compilation Execution 1.20 Assume a function requires 20 lines of machine code and will be called 10 times in the main program. You can choose to implement it using a function definition or a macro definition. Compared with the function definition, macro definition will lead the compiler to generate, for the entire program, a longer machine code but with shorter execution time. shorter machine code but with longer execution time. the same length of machine code, with shorter execution time. the same length of machine code, with longer execution time
