Can you write a new code in C language with the given values, just like this output?
QUESTION
Can you write a new code in C language with the given values, just like this output?
There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show it in simple bar graph. Use “*” and “#”characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file.

SUMMARY
Two files called group1 and group2 are stored with data of scores of few subjects. From both files, the data is read and the average score for each subject is calculated and printed as the given output. A bar graph is also shown.
EXPLANATION
Two file pointers g1 and g2 point to both the files h=group1 and group2 in reading mode. The subject names of group1 and group 2 are stored in two 2D character arrays.
Two float arrays named sum1 and sum2 contain the sum of all subject’s scores in group1 and group2 respectively. Each value is read into the array from sum1 and sum2, the average value is calculated.
The final result is shown in the form of a bar graph using ‘*’s and ‘#’ for the two groups. (group1, group2)
CODE
#include <stdio.h>
int main()
{
/* to have both the files */

FILE *g2;

g2=fopen("group2.txt","r");
char c[10][10];
char c1[10][10];
int cc=0,cc1=0;
int num1[10][20],num2[10][20];
/* getting the first string */
fscanf(g1,"%s",c[cc]);
float sum1[10],sum2[10];
/* to store the sum of score of each subject */
for(int i=0;i<5;i++)
{
sum1[i]=0;
sum2[i]=0;
}
int p1=0,p2=0;
/* processing the data in the first file */
while(1)
{
int num1;
fscanf(g1,"%d",&num1);
p1++;
if(num1==-999)
{
p1--;
sum1[cc]=sum1[cc]/p1;

if(cc1==5)
break;
fscanf(g2,"%s",c1[cc1]);
p2=0;
continue;
}
sum2[cc1]+=num2;
}
/* printing the result in the proper format */
printf("Course Course 0 10 20 30 40 50");
printf(" 60 70 80 90 100\n");
printf("ID Average ");
printf("|....|....|....|....|....|....|....|....|....");
printf("|....|\n");
for(int i=0;i<5;i++)

printf("%s %.2f ",c[i],sum1[i]);
int p1=sum1[i]/2;
int p2=sum2[i]/2;
for(int i=0;i<(p1);i++)
printf("*");
printf("\n");
printf(" %.2f ",sum2[i]);
for(int i=0;i<(p2);i++)
printf("#");
printf("\n\n");
}
}
