Question Discussion & Solution

Concept:

Polymorphism is a feature of OOPs that allows the object to behave differently in different conditions. 

Explanation:

In C++ we have two types of polymorphism:
1. Compile-time Polymorphism – This is also known as static (or early) binding.
2. Runtime Polymorphism – This is also known as dynamic (or late) binding.

Compile-time Polymorphism
Function overloading and Operator overloading are examples of Compile time polymorphism.

Concept:

• Food comprises constituents like proteins, carbohydrates, fats and supplementary substances such as minerals, vitamins and water that are vital for life.
• These constituents are known as nutrients. For proper functioning of our body, we need to consume bodybuilding foods (e.g. milk, meat, poultry, fish, eggs, pulses, groundnuts); energy-giving foods (e.g. cereals, sugar, roots, fats and oils); and protective foods (e.g. vegetables, fruits).

Explanation:

• Carbohydrates are the main source of energy for our body.
• Carbohydrates are of two types – simple and complex.
• Simple carbohydrates - These are quick-energy foods, e.g. sugar. Sources of simple carbohydrates are natural fruits, milk and milk products, and vegetables including potatoes and carrots.
• Complex carbohydrates - These are better sources of energy than sugar since they are released slowly. Sources of complex carbohydrates are bread, cereals (rice, wheat, bajra, corn, barley, ragi, sorghum, millets etc.),

Gram is not a source of carbohydrate, it is a source of protein.

Additional Information

Proteins:

• proteins are obtained from the animal as well as vegetable sources. Proteins of animal origin are found in milk, eggs, cheese, fish and meat.
• Proteins from these sources contain all the essential amino acids (EAA) in adequate amounts.
• Vegetable proteins are found in pulses (legumes), cereals, beans, nuts, oilseeds, etc

Concept:

An array is a data structure that contains a group of elements. These elements are all of the same data type, such as an integer.

To access element from an array subscript(index) and array name is required

Explanation:

Array name: A

To access 3^rd element in an array A[2] or 2[A] is used.  Therefore Both A[2] and 2[A] represent the value 3

Important point:

A[0] represent the value 1^st element
