Question 9

In programming (specifically in languages like C++), a complete statement ends with a semicolon. A period is for sentences in natural language, the # symbol is for preprocessor directives (not to end statements), and an ending brace is for blocks, not statements.

In C++, the correct syntax for including the iostream header file is #include <iostream>. Parentheses, curly braces, or square brackets are not used for standard header inclusion.

Every C++ program must have a main function as the entry point. A cout statement is for output (not mandatory), and an #include statement is for including headers (not all programs need it, e.g., a program with no input/output from standard libraries might not, but main is required).

Answer:

C) semicolon
