Answer:
// program in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variable
int inp_month;
cout<<"Enter month:";
// read month
cin>>inp_month;
// if month is february
if(inp_month==2)
cout<<"Number of days in month:28"<<endl;
// if month is 4 or 6 or 9 or 11
else if(inp_month==4||inp_month==6||inp_month==9||inp_month==11)
cout<<"Number of days in month:30"<<endl;
else
// for others month
cout<<"Number of days in month:31"<<endl;
return 0;
}
Explanation:
Read month from user and assign it to variable "inp_month".If month is 2 then there is 28 days in the month.If input month is 4 or 6 or 9 or 11 then there is 30 days in the month.For other month there will be 31 days in month.We assume there is no leap year.
Output:
Enter month:4
Number of days in month:30

Answer:
C. 2^16
Explanation:
In Computer Networking, there are five (5) classes of IP addresses, these include;
- Class A
- Class B
- Class C
- Class D
- Class E
The various classes of IP address are represented by the value of their first octet. The first octet value of Class B is 128-191 with a subnet mask of 16.
Hence, from the IP address 149.130.x.y where x and y are 8-bit numbers. The x and y equals 16-bit numbers.
Thus, 2^16 devices can connect to the Wellesley network before we run out of IP addresses.
