Create a program in C++. You may use selection statements and repetition statements. You can also use data structures such as, arrays, c-strings and structs. You may also use functions and pointers. You must incorporate the OOP up until heap memory and stack memory.
Problems include bad pointers, writing to the limit of allocated memory, and memory leaks.When it comes to memory management, C++ provides a great deal of freedom.You can allocate and deallocate memory as well as manually manipulate pointers.Freedom comes at a price. Because the language enables you to allocate memory, you can make mistakes. Similarly, you can mess up deallocation and reference use.What do you do to safeguard your code in C++ because there are no built-in safety checks?
Bad pointers, writing past the limit of memory allotted, and memory leaks are the issues.When it comes to memory management, C++ offers a tonne of freedom.You can immediately work with pointers and allocate and deallocate memory.Freedom entails a price. You can make mistakes with reservations because the language lets you do so. The use of references and deallocation are both subject to error.What can you do to secure your code since C++ lacks built-in safety checks?

- Which of the following are advantages of inline function declarations in C++ or the "Pragma Priority (x)" in Ada? they do not save push/pop variable overhead on the stack when it is called there is a lookup time required at runtime which is the same as an external function call during compile tim. Please type answer no write by hend.arrow_forwardSo, in C++ I understand using pointers and references in as function arguments, but need a bit of in depth explanation as to understanding dynamic memory allocation, and how to know when they are allocated? It is because I am confused on how memory works whenever I use pointers or references or allocating memory in C++?arrow_forwardConsider each of the following code fragments below that could be part of a C++ program. Each fragment contains a call to a standard C/C++ library function. Answer each question in one of the following three ways: - If the code fragment contains a compile-time error, write the word error for the answer. - If the code fragment contains no compile-time errors and you can determine its output at compile-time, provide the fragment’s literal output. - If the code fragment contains no compile-time errors but you cannot determine its exact output at compile-time, provide one possible evaluation and write the word example for the answer and provide one possible literal output that the code fragment could produce. (a) std::cout << sqrt(4.5) << '\n'; (b) std::cout << sqrt(4.5, 3.1) << '\n'; (c) std::cout << rand(4) << '\n'; (d) double d = 16.0; std::cout << sqrt(d) << '\n'; (e) std::cout << srand() << '\n'; (f) std::cout << rand()…arrow_forward
- The Problems: Bad pointers, writing of the end of allocated memory,memory leaks.C++ gives you lots of flexibility when it comes to memory management.You are allowed to allocate and deallocate memory and directly manipulatepointers.Flexibility comes with a cost. Because the language allows you to allocatememory, you can screw up the allocations. Similarly you can screw up thedeallocation and use of pointers.Since there are no built-in safety checks in C++ what do you do to protectyour code?arrow_forwardin c++ , fix all bugs or mistakes in code and explain in comments what was wrong and how you fix it (there can be problems with semi-columns, curly braces, included libraries, wrong usage of functions, inproper conversion of datatypes and etc.) Comment all changes in code and show the outputarrow_forwardWhich of the following are true about the comparison between 2-pass and 1-pass compilers? Choose the most correct THREE answers. Question 8 options: C language implementations are generally meant to work with 1-pass compilers. Function prototypes may be necessary in the case of a 1-pass compilation. 1-pass compilers have to see the declarations of a variable or function before it can be used in the code. Executable files generated by 1-pass compilation will result in faster running programs than 2-pass compilation. C requires pointers because of 1-pass compilation.arrow_forward
- Differentiate betwee shallow copy and deep copy, Explain the code with c++.arrow_forwardProblems include bad pointers, writing to the end of allotted memory, and memory leaks.When it comes to memory management, C++ provides a great deal of freedom. You can allocate and deallocate memory as well as directly manage pointers.Flexibility comes at a price. Because the language permits you to allocate memory, you can make mistakes. Similarly, you may mess up deallocation and pointer usage. What do you do to secure your code in C++ when there are no built-in safety checks?arrow_forwardThis exercise assesses the skills required to develop user defined functions, and pointers. Task:Develop the program with Graphics properties to give a better look to your program. You need to explore the graphics libraries available in C++ e.g. <Graphic.h> *need to solve this Q with #include <iostream> Not other libary .* Exercise 2 Write a C++ program to develop a Vehicle Fine Management System for Police. The program will have the following features.1. A user defined function called “Student Registration”. This function prompts a user to enter a student’s personal data i.e., Student Number, Student Name, Age and City and stores them. 2. A user defined function called “Module Enrolment”. This function takes student number from themain function as an argument and prompts a user to enter student two modules details i.e. Module name, Module Code and Module Credits Hours (15 or 30) and stores them. The programs should display an error message if a user enters credit hour…arrow_forward
