Question
Complete the following program to implement the user interface of the preceding exercise (above). For simplicity, only the units cm, m, and in are supported. Pleas stay in this format only.
From unit (in, ft, mi, mm, am, m, kom, oz, lb, g, kg, tsp, tbsp, pint, gal, again, uit): in To unit: cnm Enter value: l n2.54 cm From unit (in, ft, mi, mm, cm, m, kom, oz, lb,g, kg, tsp, tbsp, pint, gal, again, uit): again Enter value: 2 2 in S,08 cm From unit (in, ft, mi, mm, cm, m, kom, oz, lb,g, kg, tsp, thsp, pint, gal, again, quit): quit (Program exits)Explanation / Answer
