// 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???????
