Programming Languages Questions

  • What is the difference between a structure and class in C++?
  • Is multiple class inheritance possible in C#? Explain your answer.
  • 3. Below is how to define a constructor with default values for arguments. Time(int = 0, int = 0, int = 0); What does this mean?
  • Below is how to define a constructor with default values for arguments. Time(int = 0, int = 0, int = 0); What does this mean?
  • What are all possible ways to invoke this constructor? If such default value mechanism is not present in C++, how will you achieve the same functionality?
  • C++ enables us to use cascaded function calls. What does this mean - explain in your own words. Is it really worth the trouble? Share your thoughts.
  • Do a limited web-search to come up with an example for bad use of operator overloading, or, even better, come up with your own example. Explain why it is a bad one and how it can be improved.
  • There are no means provided by which programmers can overload the standard arithmetic operators. Once again, the effects of operator overloading can be just as easily achieved by declaring a class, appropriate instance variables, and appropriate methods to manipulate those variables. Eliminating operator overloading leads to great simplification of code. Do you agree with their assessment? Share your thoughts.
  • List any five design issues of subprograms?
  • Rewrite the following pseudocode segment in a subroutine using a loop structure in C++, C# or Java: j = 0; k = (j + 13) /27 loop: if (k > 10) then goto out k = k + 1 i = 3 * k – 1 cout<< k<
  • What does it mean to pass parameter by value?
  • How many values does a function returns?
