Answer:
The answer to the above questions is given in explanation section:
Explanation:
abstraction hides the details about a specific piece of information.
The suitable match for this is Data
Because the word "Piece of information " can only be referred to data not to process.
Now look at the second
abstraction hides the details about a specific process
The suitable match here is procedural.
because specific process can only be referred to procedure not to data.
Answer:
See explaination.
Explanation:
question is the root element which have two children one is M-C and other is Coding.
Again M-C have two sub children Points and parts
Note: The tree will be as shown in the attachment. kindly refer to attachment.
Here if we see the child of quiz(questions) at 0 position is number of type M-C and another child at location 1 is number of type Coding.
Now quiz.child(0) is number of type M-C which has two child and child at 0 is Points and child at 1 is Parts
quiz.child(0).child(1) is Points and now further points doesn't have any children hence going further to quiz.child(0).child(1).child(0) is nothing hence it will not return anything.
Next quiz.child(1) is number of type coding and value is 5.
Size of the tree is (2^depth)-1
and here depth of tree is 3 hence size is (2^3)-1 i.e. 7
Answer:
In the first expression
3 * 4 will be performed second.
In the second expression
10* 2 will be performed second.
Explanation:
In many programming language, there is an operator precedence where the operator (e.g. +, - , * , / etc) will be executed following a specific order. For example, the operator ^ which denotes power will always be executed prior to * or / and if / and * exist in the same expression, the operator positioned at the left will be executed first.
Hence, in the expression 3*2^2 < 16 , 2 will be powered to 2 (2^2) first and then only multiplied with 3.
In the expression 100 / 10 * 2 > 15 - 3, 100 will be divided by 10 and then only multiplied with 2.
A primary key is the field (or fields) that is often employed to specifically identify each record in a table.
