Question

In C write a program that must accept one argument from the command line. The argument is the name of the file containing the processes (for example: processes.csv).This file is comma-separated with three columns (process ID, arrival time and burst time) with each row for an individual process. You can assume that this file will have a maximum of 10 processes.

For example

Input: processes.csv

ProcessID,Arrival Time,Burst Time

0,1,3
1,0,5
2,9,8

3,10,6

Where the first element is processes, the second is Arrival time and the third is Burst time. Store each in separate arrays (one for processes, one for arrival and one for burst)

Thanks!

The code in the text:

int main() {
   FILE *fp1;
   char file_name[100],c; //declaration of characters
  
   printf("Enter name of the file: ");
   scanf(" %s",file_name); //taking file name
  
   fp1=fopen(file_name,"r"); //opening the file
  
   int list[30],process_id[10],Arrival_time[10],Burst_time[10],len; //decalring list
  
   c=fgetc(fp1); //taking character from fp1 pointer or file
   int i=0,number,num=0;
   while(c!='\n'){ //iterating until it hits a newline

   while(c!=EOF){ //iterate until end of file
       if (isdigit(c)){ //if it is digit
           sscanf(&c,"%d",&number); //changing character to number (c)
           num=(num*10)+number; //if it has more than 1 digit..ex:-12== 0*10+1=1 , 1*10+2=12
       }
       else if (c==',' || c=='\n') { //if it is new line or , then it will store the number in list
