C programming Homework Help-----

Please belp finish questions 3-6. I have provided my source code for earlier questions that needs to be built upon. Thank you

Directions:

Here is the sourse code to my questions that answered questions 1 and 2.

#include "stdio.h"

int main(void) { char ch[100]; // variable declaration printf("Enter a title for the data: "); fgets(ch,100,stdin); // Accept the string printf("You entered: %s ",ch); // print the title

char header1[100],header2[100]; // variable declaration printf("Enter the column 1 header: "); fgets(header1,100,stdin); // Accept the string printf("You entered: %s ",header1); // print the header1 printf("Enter the column 2 header: "); fgets(header2,100,stdin); // Accept the string printf("You entered: %s ",header2); // print the header2

return 0; }

(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 an array of strings. Store the integer components of the data points in an array 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
