Answer:
- def calcSum(d):
- sum = 0
- for x in d:
- sum += int(x)
- return sum
-
- digits = input("Please enter your digits: ")
- print(calcSum(digits))
Explanation:
The solution code is written in Python.
Firstly, create a function that take one input digit string (Line 1).
In the function, create a sum variable with initial value 0.
Use a for loop to traverse through each character in the digit string and in the loop use int method to convert each character to integer and add it to sum variable (Line 3-5) and return the sum as output.
Next, use input function to prompt user enter a digit string (Line 7).
Lastly test the function by passing the input digit as argument and print the result (Line 8).

public class Sprhere
{// Instance Data private double surfaceA, volume, r, diameter; //Constructors public Sphere ()
{r = 0;diameter = 0; surfaceA = 0;volume = 0;}
public Sphere (double radius, double d, double SA, double v)
{this. r = radius; this. diameter = d; this. surfaceA = SA;this.volume = v;}
//--------------------------------------------------------------------// Accesors.//--------------------------------------------------------------------public double get Radius()
{return r;}
public double get Diameter()
{return diameter;}
public double get SurfaceA()
{return surfaceA;}
public double get Volume()
{return volume;}
//--------------------------------------------------------------------// Mutators.//--------------------------------------------------------------------
Answer:
Option 2 i.e., instance methods is the correct answer to the following question.
Explanation:
Because the instance method or function is the function that needed the class object to be called.
<u>For Example:</u>
//header file
#include <iostream>
using namespace std;
//define class
class Test
{
public:
//instance method
void getins()
{
cout<<"I AM Instance method";
}
};
int main()
{
//creating object
Test obj;
//calling of instance method through class object
obj.getins();
}
<u>Output</u>:
I AM Instance method
Answer:
from socket import *
hostname = input('Enter the host to be scanned: ')
ip_add = gethostbyname(hostname)
connections = [ ]
for i in range(133, 136):
s = socket(AF_INET, SOCK_STREAM)
conn = s.connect_ex((ip_add, i))
print(conn)
connections.append(conn)
if 0 in connections:
print ('Host is online')
s.close()
else:
print ('system is unreachable')
Explanation:
The python source code above scans for all the available range of ports in the provided hostname, if any port is available, the host is online else the program print the error message "system is unreachable.
names = ["Kevin", "Joe", "Thor", "Adam", "Zoe"]
names.sort()
for x in names:
if x == "Thor":
break
else:
print(x)
I made up my own names for the sake of testing my code. I wrote my code in python 3.8. I hope this helps.
