This code snippet is working the first while loop but is not executing the one after it

This code is supposed to skip a line of file and write everything else in a different file, delete the original one, and rename the different one to the one deleted. Whats wrong with this code is its not working after the first file ,i.e., the second file it is niether deleted nor a new file is created with the skipped line of file. what is the issue? Does it has to do something with the rename remove function?

FILE *lnameFILE *idFILE *replname = fopen("lname.txt", "r");id = fopen("id.txt", "r");rep = fopen("rep.txt", "w+");char ch1,ch2;int temp=1,delete_line=3; /*(delete_line is supposed to be taken as an input)*/ch1 = getc(lname);  while (ch1 != EOF)  {      if (ch1 == '\n')          temp++;     if(delete_line==1){      if (temp == 2 && ch1 == '\n')          ch1 = getc(lname);}      if (temp != delete_line)          putc(ch1, rep);​      ch1 = getc(lname);  }  fclose(lname);  fclose(rep);  remove("lname.txt");  rename("rep.txt","lname.txt");  rep = fopen("rep.txt", "w+");​​  ch2 = getc(id);  while (ch2 != EOF)  {      if (ch2 == '\n')          temp++;      //except the line to be deleted      if (temp == 2 && ch2 == '\n') //making sure to skip a blank line if delete_line=1          ch2 = getc(id);​      if (temp != delete_line)          putc(ch2, rep);​      ch2 = getc(id);  }  fclose(id);  fclose(rep);  remove("id.txt");  rename("rep.txt","id.txt");
