Answer:
The answer is "Option B"
Explanation:
Conversion of type is a way of changing an entity from one data type to another. It is used to make the variable process properly by a function in computer coding.
In the C++ language, the result of the multitype value added or any other option is the result between those variables as a large type at that time, that's why choice b is correct.
Answer:
ALTER TABLE Products
ADD Products_price float(5,2) DEFAULT 9.99,
ADD Adding_time datetime;
Explanation:
So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.
Then, as per question, we need to add two columns.
The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.
And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.

A 5GL fifth-generation languages a programming language design to solve given problem without programmer. The user only needs to solve the problem and condition without implementing an algorithm.
Explanation:
First Generation Language
The first generation language is called low- level style because they were used at a superficial level of abstraction. First-generation language referred to as the native language.
Second Generation Language
The second-generation language is also low-level language or assembly language. The second level of language uses the concept of mnemonics for the writing program. Symbolic name are used.
Third Generation Language
The third-generation language overcomes the first and second-generation languages. Third generation language is considered as high- level language because the target is to focus on the logic of the program.
Fourth Generation Language
The language of generation required a lot of time and effort that affect programmers.The fourth-generation was developed to reduce the time, cost, and effort.
Fifth Generation Language
The programming language of this generation focuses on constraints programming. The fifth-generation programming languages are Artificial Intelligence and Artificial Neural Network.
