Note: Please answer in context of c++ language.

1)What is the C++ equivalent of the Java import statement?

2)What function must be in every C++ executable? Give the full function header. What is the purpose of the (optional) parameters to that function? What is the purpose of the return value?

3)What header file must be included in order to use console input and output?

4)Write a statement to print the world hello to the console along with a line break.

5)Does each of these errors come from the compiler or linker? How can each one be corrected?

• In function `_start': undefined reference to `main'
• error: cout was not declared in this scope
