Answer 1

main.cpp

#include<iostream>
#include<fstream>
#include<stdlib.h>
#include<cstdlib>
#include<string.h>
#include<ctype.h>

using namespace std;

int isColor(char buff[]){
   char colors[7][7] = {"red","blue","green","yellow","orange"};
   int x, chnge = 0;
   for(x = 0; x < 5; ++x){
       if(strcmp(colors[x], buff) == 0){
           chnge = 1;
           break;
       }
   }  
   return chnge;
}
int main(){
   char choice, buff[15];
   ifstream fin("test.txt");
   int x,y=0;
  
   if(!fin.is_open()){
       cout<<"error while opening the file\n";
       exit(0);
   }
   while(!fin.eof()){
        choice = fin.get();
int ch1 = (int)choice;
        if(ch1>=49 && ch1<=53 ){
cout<<choice<<" --- digit"<<endl;
}
else{
        if(isalnum(choice)){
            buff[y++] = choice;
        }
        else if((choice == ' ' || choice == '\n' || choice == ',') && (y != 0)){
                buff[y] = '\0';
                y = 0;               
                if(isColor(buff) == 1)
                    cout<<buff<<" --- color\n";
                else
                    cout<<buff<<" --- direction\n";
        }  
}
   }
   fin.close();
   return 0;
}

Output:
