Answer:
Several of the subsystems evolved during the program through design changes: The parachute system, essential for booster recovery, was redesigned with larger parachutes in 1983. Frangible nuts, used in the space shuttle pad hold down and release system, were redesigned in 2008.
Answer:
B
Explanation:
When you initialize an instance of FunEvent(tags, year) and assign it to bc. The instance variables in this case are: self.tags = ["g", "ml"] and self.year = 2022. But then you alter tags, which will also change self.tags, since self.tags is a reference to the list you passed in as an argument. This is not the case when you do year=2023 because, first of all, integers are not mutable, and also because even if somehow integers were mutable, you're not changing the object in-place, you're simply changing the where the "variable" is pointing to. So for example if you did tags = ["g", "ml", "bc"] instead of tags.append("bc"), it would also not change the value of the instance variable "tags", because you wouldn't be changing the object in-place. So when you print(bc), the instance variables will be ["g", "ml", "bc"] and 2022. When you try to print an object, it call try to convert it into a string using the __str__ magic method. In this case it will return a string formatted as "Event(tags={self.tags}, year={self.year}) which will output "Event(tags=['g', 'ml', 'bc'], year=2022)" So the correct answer is B

Answer:
// This program is written in C++ programming language
// Comments are used for explanatory purpose
// Program starts here
#include <iostream>
#include <string>
using namespace std;
// Declare variables
int inputvar;
// Declare output variable as array
int outputvar[32];
// Set a counter for binary array
int i = 0;
while (inputvar > 0) {
// Divide inputvar by 2 and store remainder in outputvar
outputvar[i] = n % 2;
inputvar/=2;
i++; // increment i by 1
}
// End of division
// Prin resulting array in reverse order
for (int j = i - 1; j >= 0; j--) {
cout << outputvar[j];
}
return 0;
}
// End of Program
Answer:
new Scanner(inputFile)
Explanation:
In Java when inputting a file using Scanner class. A Scanner breaks the input into tokens with the help of delimiting patterns, by default which matches the whitespaces and then the tokens that are received may be converted into values of different types by suing different next methods.
