Answer:
The answer to this question is given below in the explanation section
Explanation:
The correct answer to this question is: it used a more English-like syntax.
The software developer use high-level language to develop or author the program because it is more likely to English syntax and it would be easy for a software developer to author a program easily instead of using low level language and remembering ones and zeros.
Other options are not correct because:
It can be used on computers without microprocessors: Each computer has a microprocessor either you develop a program using high-level or low-level languages. Changes and modifications are easy in high-level language than in low-level languages. so, the option that prevents anyone from making changes to the software later is wrong. However, high-level languages are less complicated in learning and in authoring the programs but it does not use zeros and ones, it uses English-like syntax. So, the last option is also wrong.
first = input("Please input your first name: ")
last = input("Please input your last name: ")
print(last+", "+first)
I hope this helps!
Answer:
showProduct(int,double)
for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.
Explanation:
The code is
- <em>public static void showProduct (int num1, double num2){</em>
- <em> int product;</em>
- <em> product = num1*(int)num2;</em>
- <em> System.out.println("The product is "+product);</em>
- <em> }</em>
showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.
If showProduct( 10,10.0) is called the output will be 'The product is 100'.
Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.
This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
That is program ............
Explanation:
Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.
- A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
- A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.
<em> The main difference between them is that a primary key is unique but there can be many candidate keys. </em>
