Question

(1) Prompt the user for a title for data. Output the title. (1 pt)

Ex:

Enter a title for the data:
Number of Novels Authored
You entered: Number of Novels Authored

(2) Prompt the user for the headers of two columns of a table. Output the column headers. (1 pt)

Ex:

Enter the column 1 header:
Author name
You entered: Author name

Enter the column 2 header:
Number of novels
You entered: Number of novels

(3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a vector of strings. Store the integer components of the data points in a vector of integers. (4 pts)

Ex:

Enter a data point (-1 to stop input):
Jane Austen, 6
Data string: Jane Austen
Data integer: 6

(4) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message and prompt again for a valid data point.

• If entry has no comma
  • Output: Error: No comma in string. (1 pt)
• If entry has more than one comma
  • Output: Error: Too many commas in input. (1 pt)
• If entry after the comma is not an integer
  • Output: Error: Comma not followed by an integer. (2 pts)

Ex:

Enter a data point (-1 to stop input):
Ernest Hemingway 9
Error: No comma in string.

Enter a data point (-1 to stop input):
Ernest, Hemingway, 9
Error: Too many commas in input.

Enter a data point (-1 to stop input):
Ernest Hemingway, nine
Error: Comma not followed by an integer.

Enter a data point (-1 to stop input):
Ernest Hemingway, 9
Data string: Ernest Hemingway
Data integer: 9

(5) Output the information in a formatted table. The title is right justified with a setw() value of 33. Column 1 has a setw() value of 20. Column 2 has a setw() value of 23. (3 pts)

Ex:

        Number of Novels Authored
Author name         |       Number of novels
--------------------------------------------
Jane Austen         |                      6

Oscar Wilde         |                      1

(6) Output the information as a formatted histogram. Each name is right justified with a setw() value of 20. (4 pts)

Ex:

         Jane Austen ******
     Charles Dickens ********************
    Ernest Hemingway *********
        Jack Kerouac **********************
 F. Scott Fitzgerald ********

SOLUTION-
I have solve the problem in python code with comments and screenshot for easy understanding :)

CODE-

//c++ code
//header files
#include <iostream>
#include <vector>
#include <iomanip>
using namespace std;
//main
int main()
{
    //declaration of vectors
vector<string> dataStr;
vector<int> dataPoint;
string title, header1, header2,s;
//ask for input
cout<<"Enter a title for the data: ";
       getline(cin,title); //get title
       cout<<"You entered: "<<title<<endl;
       cout<<"Enter the column 1 header: ";
       getline(cin,header1);   //get header name
       cout<<"You entered: "<<header1<<endl;
       cout<<"<Enter the column 2 header: ";
       getline(cin,header2);   //get column 2 header
       cout<<"You entered: "<<header2<<endl;
       while(true){ //loop until user give -1 to exit
       cout<<"Enter a data point (-1 to stop input): ";
       getline(cin,s);
       if(s == "-1"){ //if '-1' than break
           break;
       }
       else{ //else read
       int commaCount = 0;
       for(int i=0; i<s.length(); i++){
       if(s[i] == ',')
       commaCount++;
       }
       if(commaCount == 0){
       cout<<"Error: No comma in string."<<endl;
       }
       else if(commaCount > 1){
       cout<<"Error: Too many commas in input."<<endl;
       }
       else{
       string firstWord = s.substr(0, s.find(","));
string secondWord = s.substr(s.find(",")+1, s.length()-1);
firstWord.erase(0, firstWord.find_first_not_of(' '));
secondWord.erase(0, secondWord.find_first_not_of(' '));
int countNumbers = 0;
for(int i=0; i<secondWord.length(); i++){
if(secondWord[i] >='0' && secondWord[i] <= '9'){
countNumbers++;
}
}
if(countNumbers == secondWord.length()){
                   dataPoint.push_back(atoi(secondWord.c_str()));
//dataPoint.push_back(stoi(secondWord));
                   dataStr.push_back(firstWord);
                   cout<<"Data string: "<<firstWord<<endl;
                   cout<<"Data integer: "<<secondWord<<endl;
}
else{
cout<<"Error: Comma not followed by an integer."<<endl;
}
       }
       }
    
       }
       //allignment
cout<<right<<setw(33)<<title<<endl;
cout<<left<<setw(20)<<header1<<"|"<<right<<setw(23)<<header2<<endl;
cout<<"-------------------------------------"<<endl;
for(int i=0; i<dataStr.size(); i++){
cout<<left<<setw(20)<<dataStr[i]<<"|"<<right<<setw(23)<<dataPoint[i]<<endl;
}
cout<<endl<<endl;
for(int i=0; i<dataStr.size();i++){
           cout<<dataStr[i]<<" ";
           for(int j=0; j<dataPoint[i];j++){
               cout<<"*";
           }
       cout<<endl;
