Answer : True
Explanation: Vectors can hold, data of the same type and can automatically expand accordingly and change it’s size. The date stored in vectors should be linear.
- The syntax for vector is vector<int>v;
- Mostly this is used in C++ as an alternative to arrays
- If you want to use vector in your program then define it in the header first i.e.
#include <vector>
- Push back is a function, that is used to insert an element into the vector
- Pop back removes the element from the vector
Answer:
a. 255.255.255.0 (class C)
b. 255.255.255.224
Explanation:
Here, we want to give the implied subnet mask of the given classful IPV4 address
We proceed as follows;
Given IPv4 address: 200.200.200.200
Classes
Class A : 0.0.0.0 to 127.255.255.255
Class B: 128.0.0.0 to 191.255.255.255
Class C: 192.0.0.0 to 223.255.255.255
Class D: 224.0.0.0 to 239.255.255.255
so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0
In CIDR(Classless Inter Domain Routing)
subnet /27 bits means 27 1s and 5 0s. so subnet
i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .
I'd suggest he uses
LOOKUP Function.
You can use the LOOKUP function when you need to look in a
single column or row and find a value from the same position in a corresponding
column or row. We have a much improved VLOOKUP that can also be used to search
one row or column or multiple rows and columns.
