Reading global variables from .csv file.

Question

Suppose I have .CSV file like this

Name GPA
Syam,9.7
Kumar,8.9
Anil,7.9
Suresh,8.7

Out put should come like this in .txt

Suresh got 8.7 GPA
Syam got 9.7 GPA
Anil got 7.9 GPA
Kumar got 8.9 GPA

But in the program I will write only names ( before comma values) it should replace number ( after comma values)

Ex. fprintf(fp2, "Syam got %f GPA", syam);
Whatever write name here it should replace with after comma value (9.7)

Ex. fprintf(fp2, "Average GPA of Syam and Kumar %f GPA", (syam+Kumar)/2);

Note: I want to print in fp2 sum names only. Not all the names. It should like global variables.
Before " , " global variable and after " , " global variable value.

Please let me know, if anyone knows this solution.

Answer 1

In the time it took you to write this post and describe the problem, you probably could have written 73% of the code... Anyways, please show your attempt first

Answer 2

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

/* input.csv , I want to read global variables from .csv EX. float syam = 9.8
syam,9.8
kumar,8.6
suresh,8.5
anil,5.9
girish,8.2
satish,8.8
shashi,6.8
ravi,7.8
mohan,6.9
varma,5.8
priya,9.2
gowthami,6.8
swarna,7.3
pallavi,6.7
meera,8.8 */

//Total Students in the class
// If required I will variable here with initial value 0 but variable value should read from .csv
float syam = 0;
float kumar = 0;
float suresh = 0;
float anil = 0;
float girish =0;
float satish =0;
float shashi =0;
float ravi =0;
float mohan =0;
float varma =0;
float priya =0;
float gowthami =0;
float swarna =0;
float pallavi =0;
float meera =0;

int main()
{
FILE *fp1 = fopen("input.csv", "r");
FILE *fp2 = fopen("Output.txt", "w");

while ((ch = fgetc(fp1)) != EOF);
fputc(ch, fp2);

//I want print sum student only in .txt file.

fprintf(fp2, "Syam got %.2f GPA\n",syam);
fprintf(fp2, "Girsh got %.2f GPA\n",girish);
fprintf(fp2, "Kumar got %.2f GPA\n",kumar);
fprintf(fp2, "Suresh got %.2f GPA\n",suresh);
fprintf(fp2, "Syam & Kumar got %f GPA\n",syam+kumar);
fprintf(fp2, "Average GPA of Anil,Ravi and Priya %.2f GPA\n",((anil+ravi+priya)/3));

return 0;

/* Output should be like this.
Output.txt
Syam got 9.8 GPA
Girsh got 8.2 GPA
Kumar got 8.6 GPA
Suresh got 8.5 GPA
Syam & Kumar got 18.4 GPA
Average GPA of Anil,Ravi and Priya 7.63 GPA
