Seedless fruits

Seedlessness is an essential feature of some fruits of commerce. Commercial cultivars of bananas and pineapples are exemplars of seedless fruits. Some cultivars of citrus fruits (particularly navel oranges and mandarin oranges), table grapes, grapefruit, and watermelons are valued for their seedlessness. In few species, seedlessness is the result of parthenocarpy, where fruits set without fertilization. Parthenocarpic fruit set might or might not require pollination. The majority seedless citrus fruits need a pollination stimulus; bananas and pineapples do not. Seedlessness in table grapes results from the abortion of the embryonic plant specifically produced by fertilization, a phenomenon known as stenospermocarpy which needs normal pollination and fertilization.

Friend function in C++

The Friend functions are functions defined outside a class (i.e., not member functions), but which the class declares to be friends so that they can make use of the class's private members. This is normally used in operator overloading. Perhaps the most general use of friend functions is overloading <<>> for I/O.

Another use of friend functions is to allow operators to be commutative. An operator is commutative if the end result is the same in spite of the order of its operands. Some typical examples are addition and multiplication. But, Subtraction and division are not commutative.

Vegetable

Vegetable is a cookery term which generally refers to an edible part of a plant. The definition is customary rather than scientific and is somewhat random and subjective. All parts of herbaceous plants eaten as food by humans, entire or in part, are in general considered vegetables. Mushrooms, though belong to the biological kingdom fungi, and are also normally considered vegetables. In general, vegetables are consideration of as being savory, and not sweet, even though there are many exceptions. Nuts, grains, herbs, spices and culinary fruits are generally not exact vegetables.
