C: Read a floating number that might be in the format of scientific notation

This code will read a floating number that might be in the format of scientific notation from the keyboard.
Then it will print out the number with the scientific notation and without it.

#include <stdio.h>
#include <stdlib.h>

int main() {
  printf("This code will read a floating number that might be in the format of scientific notation from the keyboard.\nThen it will print it out with the scientific notation and without\n");
  double input;
  printf("Enter a number in scientific notation. (e.g. -4e-5 or -4.00e-5 or -4.00e-05 etc.)\n");
  scanf("%lf", &input);
  printf("With scientific notation '%e'\n", input);
  printf("Without scientific notation '%lf'\n", input);
  return 0;
}
