Question
In ADA, when passing an "in out" parameter to a procedure, the system can use either pass by reference or pass by value as it sees fit, why did they do this? |
|
to allow the programmer to choose how a particular data is transferred. |
||
to optimize performance Ada will use pass by value in order to minimize side effects |
||
to save memory during compile |
||
it will use pass by reference for large data/data sets but pass by value for smaller one or primitives. |

- Question 2 This question provides an opportunity for you to demonstrate your understanding of the problem-solving approach taught in TM112 and the patterns introduced in Block 1 Part 4 and Block 2 Part 2. You can find an overview of the problem-solving approach and a list of all the patterns TM112 teaches in the Problem solving and Python quick reference and you will need to refer to this document as you work on the question. Important note: you do not need to get a working program in part a. in order to attempt part b. A student wants to design and implement a Python program to convert any 6-bit unsigned binary number to its decimal equivalent. There are many ways of doing this, but here is their initial top-level decomposition: • > Convert binary to decimal o >> Input a list of six 1s and 0s corresponding to the binary number to be converted o >> Input a list of six column weightings consisting of powers of two o >> Create a new list that contains the…arrow_forwardExplain what you mean by "execution flow."arrow_forwardC++ and pseudocodearrow_forward
