You are developing a simulation that runs in discrete time steps...
- Parallelize the simulation across multiple CPU cores.
- Decrease the resolution of the simulation.
- Use lazy evaluation for less critical calculations.
- Increase the time step size.
Parallelizing the simulation allows it to leverage the power of multi-core processors, thereby executing multiple parts of the simulation concurrently. This can lead to a substantial decrease in total simulation time, especially when there are many independent parts in the simulation.
What does the "++" symbolize in the C++ programming language?
- Double precision
- Enhancement to C
- Increment
- Two plus operations
The "++" in C++ symbolizes an "enhancement to C." Bjarne Stroustrup, when developing the language, considered C++ as an extension or improvement of the C language, hence the name C with an increment "++".
Who is the creator of the C++ programming language?
- Bjarne Stroustrup
- Dennis Ritchie
- Guido van Rossum
- James Gosling
Bjarne Stroustrup is the creator of C++. He developed it as an extension of the C programming language.
To loop over each character in a string named myString, one could use for(_______ : myString).
- auto& ch
- char& ch
- int i
- string str
Using auto& ch in a range-based for loop allows iterating over each character directly without copying. The auto keyword infers the type, making the code cleaner.
In a for loop, if a continue statement is executed, then the control jumps to _______.
- beginning of loop
- end of loop
- next iteration
- next statement
When a continue statement is encountered inside a loop, it skips the remaining portion of the current iteration and jumps to the start of the next iteration. In a for loop, this means the loop's update statement (like i++ in for(int i=0; i<10; i++)) gets executed.
What is the difference between break and continue in the context of a loop?
- break stops the loop, continue skips to the next iteration
- break skips to the next iteration, continue stops the loop
- Both have the same function
- Neither is used in loops
In a loop, the break statement is used to exit the loop prematurely, halting its execution entirely. On the other hand, the continue statement skips the remaining part of the current iteration and jumps to the next iteration.
The minimum possible value of a variable of type short int is _______.
- -32768
- 0
- -1024
- -2147483648
The short int type in C++ is typically 16 bits in size. Given that it's signed, half of the 2^16 possible values are negative. The range thus typically starts at -32768 and goes up to 32767.
What is the primary benefit of using class templates in C++?
- Faster execution
- Reduced memory usage
- Code optimization
- Genericity
Class templates in C++ provide the ability to create classes that can work with a variety of data types without the need to redefine the class for each type, offering a level of genericity and flexibility in code design.
The concept of Streams in C++ was introduced in the standard with _______.
- C++03
- C++11
- C++14
- C++98
Streams, which are part of the C++ Standard Library, were formalized in the C++98 standard. They provide a mechanism to perform input and output operations.
In which type of inheritance do all derived classes share a common base class?
- Multiple Inheritance
- Hierarchical Inheritance
- Multilevel Inheritance
- Hybrid Inheritance
Hierarchical Inheritance is when multiple derived classes inherit from a single base class. All the derived classes share the features of that one common base class. This kind of inheritance structure resembles a hierarchy or tree structure.
