Answer:
True
Explanation:
While programming in most programming languages, one will have need to use functions and variables defined in other class libraries. in C++, these functions and variables' definitions are contained in Header files, which can be imported and used into any C++ program by using the pre-processor #include statement. This statement is the equivalent of import in java and copy in other languages. Popular header files are the Maths class (Allows use of maths functions like power, square roots exponentiation etc), the input/output (allows usage of cout print statement and cin input statement)
Answer:
The answer is "option B".
Explanation:
In the given code, four double variable "len1, len2, len3, and total" is declared, in which the first three variables accept some value, and in the total variable, we add those variable. In the next step, an integer variable minLength is defined, which converts the decimal value to an integer and adds the value that is "0.5". In this section, the code uses as an intended purpose but only if the total of 3 lengths is equivalent to or larger then 0.5, and wrong choices can be described as follows:
- In option A, It accepts the negative value, that's why it is wrong.
- Option C, Option D, and Option E all were wrong because the code segment is work as intended.
It refers to a massive amount of data that keeps on growing exponentially with time. It is so voluminous that it cannot be processed or analyzed using conventional data processing techniques. It includes data mining, data storage, data analysis, data sharing, and data visualization.
