Question

in c++

Write a program that allows the user to type in any one-line question and then answers that question. Your program won't really respond to the question, rather it will read a random response from a file.

Requirements

Your program should have a function called getQuestion() which prompts the user for a question and returns the number of characters in the question (including spaces and punctuation, not including the ending newline). If the user enters an empty string they should be given an error and prompted to enter another question.

So, if the user types What is the meaning of life? getQuestion() will return 28.

Your program should have a function called writeAnswers() which accepts an ofstream parameter. Opening and closing the file should be handled outside writeAnswers(). The function writes into the file connected to the ofstream exactly the following text (which are your answers):

I'm not sure, but I think you will find the answer in Chapter #.
That's a good question! You should google it.
If I were you, I would not worry about such things.
That question has puzzled philosophers for centuries.
I don't know. I'm just a machine.
The answer is 42.
Think about it and the answer will come to you.
I used to know the answer to that question, but I've forgotten it.
The answer can be found in a secret place in the woods.

Your program should have a function called displayAnswer() which receives an ifstream parameter and an int parameter. The ifstream parameter should be connected to the file containing the answers. Opening and closing the file should be handled outside displayAnswer().

The int parameter should be the number of characters in the question asked. displayAnswer() then displays the answer from the ifstream file on the line number that is the result of: (number of characters in the question) % 9 + 1. We use 9 because that is the number of answers in the file.

For instance, What is the meaning of life? has 28 characters, 28 % 9 +1 = 2. So the answer displayed would be line 2 in the file, "That's a good question! You should google it."

If line 1 is selected for printing, replace the # with a random number from 1 to 18 before displaying. So, if the random number selected was 5 it would display "I'm not sure, but I think you will find the answer in Chapter 5."

After displaying the answer your program should ask the user if they'd like to ask another question. If they input Yes it should prompt for another question and answer it. The program should repeat until the user enters No.

add. notes

//displayAnswer() which receives an ifstream parameter and an int parameter.- function should use get to read char by char till line end char

"ch =char"

should look something like

for (inti=1,i

do

{

infile.get (ch);

while (ch != '\n')

}

reset ch

while(ch != '\n')

{infile.get(ch)

if ((position==1)&&(ch=='#')

make random #

cout<

else

cout <

//function called writeAnswers() should create a .txt file that is populated with the answers the first time it runs

the random number should be seeded with time

Output

Enter your question? What is the meaning of life?
That's a good question! You should google it.
Do you want to continue(yes/no)? yes
Enter your question? Are you looking for something?
That question has puzzled philosophers for centuries.
Do you want to continue(yes/no)? no
         Thank you!!!
