Problem 1
What does it mean to say that a programming language is machine independent?
Problem 6
What are the three different levels of programming languages?
Problem 7
Suppose the function \(f\) expects a string as its input and returns a new string as its output made by removing odd-position letters from the input string. What is the result returned by the function \(f(f\) ("programming"))?
Problem 8
Suppose the function \(f\) expects two numeric values as its inputs and returns their addition as its output value, and \(g\) is a function that returns the subtraction of the two values given as its input. If \(a\) and \(b\) represent numeric values, what is the result returned by \(f(f(a, b), g(a, b))\) ?
Problem 9
Suppose you are going to write an object-oriented program for calculating grades of students. What data should be stored inside the object representing a student's grades? To what messages should that object be able to respond? What are the different objects that might be used in the program?
Problem 10
Summarize the distinction between a machine language and an assembly language.
Problem 13
Summarize the distinction between the declaration and the definition of a variable.
Problem 14
Explain the differences between a local variable and a global variable.
Problem 15
a. What is operator precedence? b. Depending on operator precedence, what values could be associated with the expression \(6+2 \times 3 ?\)
Problem 16
Explain the advantages of code reuse.
