Answer:
- def getCharacterForward(char, key):
- charList = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
-
- if(len(char) > 1):
- return None
- elif(not isinstance(key, int)):
- return -1
- else:
- index = charList.find(char)
- if(index + key <= 25):
- return charList[index + key]
- else:
- return charList[(index + key)% 26]
-
- print(getCharacterForward("C", 4))
- print(getCharacterForward("X", 4))
Explanation:
Firstly, define a charList that includes all uppercase alphabets (Line 2). We presume this program will only handle uppercase characters.
Follow the question requirement and define necessary input validation such as checking if the char is a single character (Line 4). We can do the validation by checking if the length of the char is more than 1, if so, this is not a single character and should return None (Line 5). Next, validate the key by using isinstance function to see if this is an integer. If this is not an integer return -1 (Line 6 - 7).
Otherwise, the program will proceed to find the index of char in the charList using find method (Line 9). Next, we can add the key to index and use the result value to get forwarded character from the charList and return it as output (Line 11).
However, we need to deal a situation that the char is found at close end of the charList and the forward key steps will be out of range of alphabet list. For example the char is X and the key is 4, the four steps forward will result in out of range error. To handle this situation, we can move the last two forward steps from the starting point of the charList. So X move forward 4 will become B. We can implement this logic by having index + key modulus by 26 (Line 13).
We can test the function will passing two sample set of arguments (Line 15 - 16) and we shall get the output as follows:
G
B
Answer and Explanation:
Using JavaScript:
/* program should take N input which represents the dollar amount and output how many chocolate bars and how many coupons we have*/
function chocolatebar(dollars){
var dollaramt= dollars;
var i;
for(i=0; i <= dollaramt; i++){
i=i+6
?
Alert ("you have 1 extra chocolate bar");
:
Alert ("keep buying chocolate bars to get more coupons for a bonus chocolate bar")
}
}

Answer: Operating system
Explanation:
A computer's OS (operating system) is one of the type of computer software and the main function of an operating system is that it helps in managing the hardware, processes, memory and the software of the computer application.
An operating system basically providing the set of instruction to the computer for the communication purpose and perform various types of task in the computer system.
According to the given question, an operating system is refers to the software program that helps in coordinating all the task and the activities in the computer system.
Therefore, Operating system is the correct answer.
Answer:
Option B.
Explanation:
The delete key is used to delete the symbol after the insertion point.
Here, Michal is typed as Michael.
So, to delete the letter e from Michael, put the insertion point before e.
If you put insertion point after the letter e or before the letter l, l gets deleted.
In no case, you can put the insertion point after the letter l.
So, option B is correct.
