Answer:
Option (B) is the correct answer to the following question.
Explanation:
Here, in the code "const" is the constant keyword which is used when we need that the value stored in that variable will never change.
The following option is correct because the assignment operator are those operator which initialize the value in the variable and overloading of the assignment operator would be as we use the other operators and also we could use them by creating the objects as we use in the copy constructor.
So, that's why the following option is correct.
The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches of rain falls yearly. Rain forests belong to the tropical wet climate group.
Explanation:
- The temperature in a rain forest rarely gets higher than 93 °F or drops below 68 °F. The average humidity is between 77 and 88%, rainfall is often more than 100 inches a year. In monsoonal areas, there is a real dry season.
- Rainforests now cover less than 6% of Earth's land surface. Tropical rainforests produce 40% of Earth's oxygen.
- About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, is used as an anesthetic and to relax muscles during surgery. Quinineis used to treat malaria.
- There are four very distinct layers of trees in a tropical rain forest. They are the emergent, upper canopy, understory, and forest floor.
- The soil of the tropical rainforests is shallow, poor in nutrients and without soluble minerals. Years of rainfall have washed away the nutrients in the soil obtained from weathered rocks.
- The tropical rain forest can be found in three major geographical areas around the world.
-
Central America in the the Amazon river basin. Africa - Zaire basin, with a small area in West Africa. Indo-Malaysia - west coast of India, Assam, Southeast Asia, New Guinea and Queensland, Australia.
