Question

**C programming Language

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

ata integer: 6

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int num; //global variable to store numeric valu after comma

//function to check comma present in input string or not
int check_comma(char s[50])
{
int i,pos,count=0;
for(i=0;i<strlen(s);i++)
{
if(s[i]==',')
{
count++;
pos=i;
}
}
if(count==1)
return(pos);
else if(count==0)
return(-1);
else
return(-2);
}

//function to check numeric values present after comma or not
//if yes then store in global variable num
int check_Int(char s[50], int pos)
{
int i;
num=0;
for(i=pos+1;i<strlen(s);i++)
{
if(s[i]>=48 && s[i]<=57)
num=num*10+(s[i]-48);
else
return 0;

}
return 1;
}
int main()
{

else

}
/*printf("\nNumbers are: ");
