a. With respect to scope, why are modules (or namespaces) useful? b. Why do locally declared arrays in C++ need to have a fixed size? c. Explain why C++ still has to perform type inference even though each variable must be explicitly declared with a type.
Solve the following question correctly please. When a program that uses the constructor overloading is compiled, C++ compiler checks the number of parameters, their order and data types and marks them differently.
There is a new C++ STL called Boost. Based on your researches, in what situations you'd use STL, in which cases, you would prefer using Boost library? Please explain in detail.
The issues:Memory leaks, bad pointers, and writing to the end of the memory allotted.When it comes to memory management, C++ offers a tonne of freedom. You can directly work with pointers and allocate and deallocate memory. Flexibility entails a price. You can make mistakes with allocations because the language lets you do so. The usage of pointers and deallocation are both subject to error. What can you do to secure your code because C++ lacks built-in safety checks?

Print "Learn more CPP" in C++. Please print the above line using cout.
I need to create a minifloat for a 8 bit binary on c language.
Is it preferable to use fully qualified references or unqualified references when referencing a subprogram, variable, or object in code? Issues with C's primitive encapsulation and how they manifest in C++ are discussed.
Hi everyone I'm learning c++ but I don't understand pass-by-value and pass-by-reference. What is (const &)? Why do we have to pass const with & but not just &? please explain, thank you so much!
i need answer of this question in 30 minutes. Explain what is diamond problem in C++ in your own words?
Please I need to answers these questions in C++. Thank you. Question: Does the if-else if structure offer any advantages over nested if statements? Choose the correct answer from below: A. It helps keep the code understandable and readable on the screen or on paper B. It does away with the need of a trailing else C. It can handle logic that nested if statements cannot handle D. Neither has an advantage over the other E. The text did not discuss this topic Question: What is the purpose of a trailing else in an if-else if ladder structure? Choose the correct answer from below: A. It handles the "none of the above" situation in the problem B. Two of the other answers are correct C. It is often used to catch errors D. It deals with the most complex boolean expression E. It is the only part of the ladder that is not optional
Which is better for referencing code subprograms, variables, and objects: references that are properly qualified or those that are not? C's primitive encapsulation and how it affects C++ are explained in this post.
