Question 1 1.1 In your own words discuss similarities and differences between a function and a small program. 1.2Define a function named average grade. This function returns a double and has four double arguments, testi, test2, test3, test4. The return value should be the average, or arithmetic mean of the four arguments. Be sure to include a comment that tells briefly what the function does 1.3 Find the errors in the following class and explain how to correct them: class Example public: Example( int y = 10 ) : data( y // empty body 1 // end Example constructor int getIncrementedData ( ) const return data++; 1 // end function getIncrementedData static int getCount() { cout << “Data is ” << data << endl; return count; 1 // end function getCount private: int data; static int count; 1; // end class Example 1.4 Write an if-else statement using a C-string function that reports whether two C-strings variables contain the same C-string. Question 3 3.1 Please explain why the statement “Mixing call-by-reference and call-by-value parameters is strictly prohibited” is false. 3.2 If, in a class, one uses the keyword pub 1 ic : , it affects only the member that immediately follows the keyword public, making this member accessible to any other function defined anywhere. Explain why above statement is Wrong. Question 2: 2.1 If, in a class, one uses the keyword pub 1 ic : , it affects only the member that immediately follows the keyword public, making this member accessible to any other function defined anywhere. Explain why above statement is Wrong. 2.2 Suppose you have a class whose objects are very, very large. Briefly, describe the advantages and drawbacks of call-by-value and call-by-reference for large objects. Describe a parameter passing mechanism that will allow the safety of call-by-value and the efficiency of call-by-reference. 2.3 Write an if-else statement using a C-string function that reports whether two C-strings variables…
