Answer:
public: virtual void print()=0;
Explanation:
An abstract class contains a pure virtual function. Pure virtual class cannot be instantiated but it can be subclassed and the subclass can provide an implementation of the function.
A virtual function declaration in the class is preceded by the virtual keyword. For example, virtual void print();
A pure virtual function declaration is followed by '=0;'
public: virtual void print()=0;
Answer:
Explanation:
The following code is written in Python. It creates a class that takes in one ArrayList parameter and loops through it and calls two functions that check if the numbers are Perfect, Odd, or Even. Then it goes counting each and printing the final results to the screen.
class NumberAnalyzer:
def __init__(self, myArray):
perfect = 0
odd = 0
even = 0
for element in myArray:
if self.isPerfect(element) == True:
perfect += 1
else:
if self.isEven(element) == True:
even += 1
else:
odd += 1
print("# of Perfect elements: " + str(perfect))
print("# of Even elements: " + str(even))
print("# of Odd elements: " + str(odd))
def isPerfect(self, number):
sum = 1
i = 2
while i * i <= number:
if number % i == 0:
sum = sum + i + number / i
i += 1
if number == sum:
return True
else:
return False
def isEven(self, number):
if (number % 2) == 0:
return True
else:
return False
Answer:
D. Low-level components are combined into clusters that perform a specific software sub-function
Explanation:
Normally, regression testing are done on a manual basis by simply re-executing a subset of the entire available test cases or it can be done automatically by utilizing playback tools or automated capture. Hence, from the options, a combination of low-level components into clusters that perform a specific sub-function does not align with how regression testing are done either manually or automatically.
