First, we have to understand what scope is. When variables are declared, they are only available in the code block they're declared in, unless they're global variables (this doesn't apply here).
strFirst is declared in usernameMaker and that is the only place it is available in.

Answer:
In the given question the first line is correct, i.e. "Describes the inputs, outputs, and processing logic for all program modules".
Explanation:
The documentation is a recorded text or image, which is preceding or in the code base of the programs, whether it describes how well the program works and how it is being used, and things in various positions can be influenced by people, and the wrong option can be described as follows:
- In the documentation, it can't consist of rules and data.
- In can't include a dictionary, flow maps, screen designs and device requests that began the program.
- In can't provide links within the program.
Answer:
a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.
b. 195.200.0.0/22
Explanation:
195.200.0.0/16
The number of bits to give 512 is 9
2^9=512
2^8=256 which is not up to our expected 320 customers that requires a network ip
Note we have to use a bit number that is equal or higher than our required number of networks.
The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126
The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.
b. 64 customers requires 6 bits to be taken from the host bit to the network bit
i.e 2^6 = 64
195.200.0.0/22
The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet
This network meet the requirement " 64 customers want 128 addresses/customer "
