This question requires you to implement a slightly more valuable AI English question and answer program. The rules are:
- No matter what the user says, first print out what the other party said in one line;
- Eliminate extra spaces in the original text: replace multiple spaces between adjacent words with 1 space, delete all spaces at the beginning and end of the line, and delete spaces before punctuation;
- Change all uppercase English letters in the original text to lowercase, except
I; - All the original separate
can you,could youcorrespondingly replacedI can,I could- where "independent" means that the word is separated spaces or punctuation; - The text of all independent
Iandmereplacedyou; - Replace all the question marks in the original text with
?exclamation marks!; - Output the replaced sentence in one line as AI's answer.
Input format:
Enter a positive integer N that does not exceed 10 in the first line, and then N lines. Each line provides a user's dialogue with no more than 1000 characters and ending with a carriage return. The dialogue is a non-empty string and only includes Letters, numbers, spaces, visible half-width punctuation marks.
Output format:
Output according to the requirements of the question, AI: and add a space before each answer of AI .
Input sample:
6
Hello ?
Good to chat with you
can you speak Chinese?
Really?
Could you show me 5
What Is this prime? I,don 't know
Sample output:
Hello ?
AI: hello!
Good to chat with you
AI: good to chat with you
can you speak Chinese?
AI: I can speak chinese!
Really?
AI: really!
Could you show me 5
AI: I could show you 5
What Is this prime? I,don 't know
AI: what Is this prime! you,don't knowI really wrote for a long time

int is_eors( char c)//is empty or symbol, must be written, used to classify characters
{
if(isdigit(c)||isalpha(c))
return 0;
if(c==' ')
return 1;

}
isalpha() function: determine whether a character is an English letter
islower() function: determine whether a character is a lowercase letter
isdigit() function: determine whether a character is a number
1⃣️ Determine whether the sentence is all empty
2⃣️ Replace uppercase with lowercase and? Replace with!
3⃣️nsp(not_space) remove extra spaces
❀Add empty characters at the beginning and end of nsp to deal with the following replacements for I or me
string nsp=" ";
for(int i=0;i<len;i++)
{
if(s[i]==' '&&s[i-1]==' ')
continue;
else
nsp+=s[i];
}
nsp + = '';
4⃣️out to replace words and phrases
❀Just copy to the new string and skip the replacement part of the original string
if(nsp[i+1]=='I'&&is_eors(nsp[i])>0&&is_eors(nsp[i+2])>0)
{
i++;
out+="you";
}
5⃣️Remove trailing spaces
for(int i=len-1;i>=0;i--)
{
if(out[i]!=' ')
{
len = i;
break;
}
}
for(int i=0;i<=len;i++)
6⃣️Remove the leading space and the space before special characters and output
int t=0;
for(int i=0;i<=len;i++)
{
if (i>0&&out[i]==''&&is_eors(out[i+1])==2)//Skip spaces before special characters
continue;
else if(out[i]!=' ')
{
cout<<out[i];
t++;
}
else if (out[i]==''&&t>0)//Skip the leading space
{
cout<<" ";
}
}
