Your program will have to read them all into memory then keep only the ones you want.

>>which function should i use

Its not a function at all. Its called an algorithm. Use ifstream to open the file as a normal text file then in a loop use >> operator to read each of the columns in each row.

something like this will do:

ifstream infile;
     
    infile.open("datafile.txt");
      
    do
    { 
  
    infile>>elements>>entity;   
       
    }while(!infile.eof());

but you have to make it array
