Answer:
The program written in Python is as follows:
<em>See Explanation section for line by line explanation</em>
for n in range(100,1000):
isum = 0
for d in range(1,n):
if n%d == 0:
isum += d
if isum == n * 2:
print(n)
Explanation:
The program only considers 3 digit numbers. hence the range of n is from 100 to 999
for n in range(100,1000):
This line initializes sum to 0
isum = 0
This line is an iteration that stands as the divisor
for d in range(1,n):
This line checks if a number, d can evenly divide n
if n%d == 0:
If yes, the sum is updated
isum += d
This line checks if the current number n is a double-perfect number
if isum == n * 2:
If yes, n is printed
print(n)
<em>When the program is run, the displayed output is 120 and 672</em>
Answer:
Option B is correct.
Explanation:
Within Techno Info Systems the user has been analyst contemplating that four-model concept towards computer development for such its new customer. When they adopt that four-model method, thus the result seems to be the time taken to implement the rises in the method.
So, therefore the other options are incorrect according to the following scenario.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
string fname,lname; int num;
cout<<"Firstname: "; cin>>fname;
cout<<"Lastname: "; cin>>lname;
cout<<"4 digits: "; cin>>num;
string login = lname;
if(lname.length()>=5){
login = lname.substr(0, 5); }
login+=fname.substr(0,1)+to_string(num%100);
cout<<login;
return 0;
}
