SOLUTION :

CONSIDERING THE CONDITIONS AND REQUIREMENTS FROM THE QUESTION.

HERE CODE

#include <stdio.h>
#include <stdlib.h>

int main()
{
FILE *fptr;
int count=0, agesum=0,gradesum=0,in=0, online=0; //the number of entries
char filename[100], c, Name[],Attending[], extract[1000];
int ID[], Age[], Grade[], t=0, m=0, k=count-1;

printf("Enter the filename to open \n");
scanf("%s", filename);

// Open file
fptr = fopen(filename, "r");
if (fptr == NULL)
{
printf("Cannot open file \n");
exit(0);
}

// Read contents from file
c = fgetc(fptr);
while (c != EOF && c=='\n')
{
count+=1;
c = fgetc(fptr);
}

c = fgetc(fptr);
Name= new char [count];
Attending= new char [count];
ID= new int [count];
Age= new int [count];
Grade= new int[count];

while (c != EOF && m<5 && k>=0) //storing values in seperate arrays Name, Attending, Age, Grade
{ //m is used for keeping count of the no. of columns or array names and k is used to keep count of the number of entries or rows   
if(c=='\n')
m=0;
else{
do{
extract[t++]=c;
c = fgetc(fptr); }
while(c!=',');
if(m==0)
Name[count-1-k]=extract;
else if(m==1)
Attending[count-1-k]=extract;
else if(m==2)
ID[count-k]=extract;
else if(m==3)
Age[count-1-k]=(int) extract;
else if(m==4)
Grade[count-1-k]=(int) extract;
k-=1;
m+=1;
extract="";
}
}

for(int i=0; i<count ; i++)
{
printf("Name: %s", Name[i]);
printf("Attending: %s", Attending[i]);
if(Attending[i]=="Online")
online+=1;
else in+=1;
printf("ID: %s ", ID[i]);
printf("Age: %d", (int)Age[i]);
agesum+=Age[i];
printf("Grade: %f", (float)Grade[i]);
gradesum+=Grade[i];
}

printf("Number of in persons is %d", in);
printf("Number of online persons is %d", online);
printf("The average age is: %f", (agesum/count));
printf("The average grade is: %f",(gradesum/count));

fclose(fptr);
return 0;
}

NOTE : PLEASE UPVOTE ITS VERY MUCH NECESSARY FOR ME A LOT. PLZZZZ....A
