Answer:
False
Explanation:
An abstract class is a class declared abstract — it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.
<u></u>
<u>Abstract method declaration</u>
abstract void moveTo(double X, double Y);
Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.
<u>Example</u>
public abstract class GraphicObject {
// declaring fields
// declaring non-abstract methods
abstract void draw();
}
Answer:
misspelling a programming language word
Explanation:
Syntax error is the type of error in programming, when the programmer insert some symbol that is not present in directories or libraries, the programmer not followed the rules of that particular programming language that is understandable to compiler.
For example in C++, it is necessary to insert the semicolon (;) after each statement. If the programmer not insert the semicolon after each statement, the program will show the syntax error.
If the programmer use integer instead of int to assign datatype to the variable in C++, it will also leads to the syntax error. Because in C++ library, Integer is defined with the help of "int".
Answer:
Explanation:
Following are the Semaphores:
Customers: Counts waiting customers;
Barbers: Number of idle barbers (0 or 1)
mutex: Used for mutual exclusion.
Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves
Shared data variable:
count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.
// shared data
semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;
int count_cust= 0;
void barber() {
while(true) { //shop is always open
wait(customers); //sleep when there are no waiting customers
wait(mutex); //mutex for accessing customers1
count_cust= count_cust-1; //customer left
signal(barbers);
signal(mutex);
cut_hair();
}
}
void customer() {
wait(mutex); //mutex for accessing count_cust
if (count_cust< n) {
count_cust= count_cust+1; //new customer
signal(customers); signal(mutex);
wait(barbers); //wait for available barbers get_haircut();
}
else { //do nothing (leave) when all chairs are used. signal(mutex);
}
}
cut_hair(){ waiting(cutting);
}
get_haircut(){
get hair cut for some time; signal(cutting);
}
Answer:
def isdivisible():
maxint=input("Enter the Max Int")
int1=0
int2=0
int1=input("Enter the first Integer")
int2=input("Enter the second Integer")
tup1=(int1, int2)
print(tup1)
i = 1
for i in range(1, int(maxint)-1):
if int(tup1[0])%i==0 & int(tup1[1])%i==0:
print(i)
else:
continue
isdivisible()
1.2 Outputs
First test case:
Enter the Max Int6
Enter the first Integer2
Enter the second Integer8
('2', '8')
1
2
Second test case: returning empty list
Enter the Max Int2
Enter the first Integer13
Enter the second Integer27
('13', '27')
Test case 3:
Enter the Max Int4
Enter the first Integer8
Enter the second Integer10
('8', '10')
1
2
Explanation:
The program is as above, and the three test cases are also mentioned. We have created a tuple out of two input integer, and performed the output as required.
