//hi experts,
  //              i can't get the following code to read in  multiple times after the 
"more(y/n)" printout. it does not scan a second time it just exists the loop after just once 
//can you please fix the bug in this simple program.

char op = 'y';

while(op == 'y') 
  printf("Enter formula: ");
  l = strlen(molecule);

 printf("More? (y/n) : "); // THIS DOES NOT WORK???
 scanf("%c",&op);       //      WHY???????


return 0;
