Answer:
error: incompatible types
Explanation:
Given
The attached code
Required
The output
Variable "a" is declared as float
While p is declared as a pointer to an integer variable
An error of incompatible types will be returned on line 3, <em>int *p = a;</em>
Because the variables are not the same.
To assign a to p*, we have to use type casting.
Hence, (b) is correct
Answer:
1) the wireless standards that can be implemented are; IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n. The pros and cons are in the attachment
2) 802.11g can be implemented in alice's restaurant. This is because it provides the fastest speed and has a wide range which will not be easily disturbed by other devices
3) Please check the attachment
4) Please check the attachment.

Explanation:
readline() method is used to read one line from a file. It returns that line from the file.
This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.
So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.
For example if the file "abc.txt" contains the lines:
Welcome to abc file.
This file is for demonstrating how read line works.
Consider the following code:
f = open("abc.txt", "r") #opens the file in read mode
print(f.readline()) # read one line from file and displays it
The output is:
Welcome to abc file.
The readline() method reads one line and the print method displays that line.
