$9\mathrm{.}12$ LAB: Nutritional information $($classes$/$constructors$)$

Complete the Fooditem class by adding a constructor to initialize a food item. The constructor should initialize the name $($a string$)$ to

"Water" and all other instance attributes to $0\mathrm{.}0$ by default. If the constructor is called with a food name, grams of fat, grams of

carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value.

The given program accepts as input a food item name, amount of fat, carbs, and protein, and the number of servings. The program creates

a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional

information and calories per serving for a food item.

Ex: If the input is:

Water

the output is:

Nutritional information per serving of Water:

Fat: $0\mathrm{.}00g$

Carbohydrates: $0\mathrm{.}00g$

Protein: $0\mathrm{.}00g$

Number of calories for $1\mathrm{.}00$ serving$($s$)$: $0\mathrm{.}00$

E

$\frac{M}{\text{\&}}M\text{'}s$

$10\mathrm{.}0$

$34\mathrm{.}0$

$2\mathrm{.}0$

$3\mathrm{.}0$

where M&M$\text{'}$s is the food name, $10\mathrm{.}0$ is the grams of fat, $34\mathrm{.}0$ is the grams of carbohydrates, $2\mathrm{.}0$ is the grams of protein, and $3\mathrm{.}0$ is the

number of servings, the output is:

Nutritional information per serving of M&M$\text{'}$s:

Fat: $10\mathrm{.}00g$

Carbohydrates: $34\mathrm{.}00g$

Protein: $2\mathrm{.}00g$

Number of calories for $1\mathrm{.}00$ serving$($s$)$: $234\mathrm{.}00$

Number of calories for $3\mathrm{.}00$ serving$($s$)$: $702\mathrm{.}00$

Note: The program outputs the number of calories for one serving of a food and for the input number of servings as well. The program only

outputs the calories for one serving of water.
