Answer:
Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.
Explanation:
Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.
<u>Implicit type casting:</u> The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.
Ex:

In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.
<u>Explicit type casting:</u> The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.
Ex: 

In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).
The user needs to complete the entire disk surface first before starting another surface.
Explanation:
When you are using a multiple disk storage system to write the data the disk automatically writes the disk based on the algorithm for better efficiency and availability of the disk space.
hence when you are recording a data on a multiple disk storage system, it is recommended to fill the complete disk surface initially before you start the another surface to record the data.
Answer:
B) Worksheet
Explanation:
In Microsoft Excel and all the other spreadsheet applications, a worksheet is a file that contains cells, the cells are an intersections of rows and columns, and it provides the interface where the users can input and modify data, because of the row/column nature of worksheets, a table structure can easily be developed for the organization of data/information from where they can be plotted to a chart. Hence every chart has a corresponding worksheet containing its numerical data.
Answer:
Do you know what is best about America? It’s really the fact that the right to equality has been ensured at the maximum level, and for all. And the citizens respect their family and this is being showcased proudly by Sir Donald Trump who not only looks after the whole US without ever hesitating no matter whatever might be the issue and at the same time also look after his great and proven proud family. And that explains in itself why America is so great. And this is a perfect specimen of an inordinate democracy, and that is why American Democracy is so fruitful. There is sufficient money, all sorts of resources, the most influential military, and the world's finest technology. And American history can be a petite one, but it is one of the most noticeable histories in the entire world. You will not find such a great history in any other part of the world. And George Washington, the father of the country set such an example that the next various generations of great leaders were able to build such a great America. It is a society where every citizen enjoys equal rights, and a day before Sir Trump issued various prisoners with graduate degrees, to help them to return to the mainstream of life. No other society in the whole world enjoys such a level of privileges on behalf of equality. And that’s why the US society can be termed as the most normal in the whole world.
Explanation:
Please check the answer section. And I have chosen US as it is the most fruitful democracy of the world. And I feel all the counrtries from the entire world, should learn a lesson from the short history of United States. This is the way in which we can sight a normal society.
