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.  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.  If entry has more than one comma Output: Error: Too many commas in input. If entry after the comma is not an integer Output: Error: Comma not followed by an integer. 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.
