- Memory Allocation: Select all of the following statements that are true. The basic idea of contiguous allocation is that each process is contained in a single contiguous section of memory. When using a single-partition allocation scheme, the main memory is usually divided into three partitions. Memory partitioning schemes allow for multiprogramming. When applying the multiple-partition allocation scheme "Fixed Partitions", all partitions always have the same size. When applying the multiple-partition allocation scheme "Variable Partitions", the FirstFit allocation strategy performs best in practice. The Buddy system is prone to internal fragmentation.Addressing and Address Binding: Select all of the following statements that are true. Direct addressing means that the address to be accessed is located elsewhere. Relocatable code must be generated if the memory location to be used is not known at compile time. Relative addressing means that the address to be accessed is specified as a distance from a reference address. Absolute addressing means that the address to be accessed is specified completely and without other reference addresses. Address binding is not possible during execution time. The logical address space is bound to a separate physical address space.Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.
- QUESTION 6 Which of the following is NOT true? (Choose all that apply) 01. None II. A dangling pointer is an allocated stack-dynamic pointer variable without any reference. III. Dangling pointers are harmful for the programs. OV. A program with memory leak is free from creating garbage.28. Which statement of the following is the most appropriate? Group of answer choices The size of a dynamic array needs to be determined at compilation. Such behavior, determined at compile time, is called dynamic behavior. Dynamic behavior is more flexible than decisions that are made at run time (i.e., static behavior). The size of a dynamic array does not need to be determined until a program is running. Such behavior, determined at run time, is called dynamic behavior. Dynamic behavior is more flexible than decisions that are made at compile time (i.e., static behavior). The size of a dynamic array does not need to be determined until a program is running. Such behavior, determined at run time, is called static behavior. Static behavior is more flexible than decisions that are made at compile time (i.e., dynamic behavior). The size of a dynamic array does not need to be determined until a program is running. Such behavior, determined at run time, is called static…What is the difference between 'delete' and 'deletel' in C++? Select one: a.delete is the correct operator, but deletel operator does not exist b.delete is used to delete automatic objects whereas deletel is used to delete pointer objects c.delete is used to delete single dynamic object whereas deletel is used to delete dynamic array objects d.delete is a keyword whereas delete] is an identifier

Design the constructor function that decides the number of player in the team and initializes code for each player. Create a team and display its all data. (Implement dynamic memory allocation).A pointer variable is what? Then what? A dynamic array is a What's the deal with dynamic arrays and pointers?
- C++ Create a new file called pointerBasics.cpp. Write a C++ program in this new file. In this new file, write code that will do the following: Declare and assign values to variables Declare an integer variable called myInt and assign the value 15 to it. Declare a pointer variable called myPointer using the dereference operator (*) and assign it to the memory location of myInt using the address-of operator (&) Print to console Print the memory location of myInt (remember the address-of operator!) and the value of myPointer. Print the value of myInt and the value pointed to by myPointer (remember the dereference operator!) Change values and print to console Change the value of myInt to 10. Print the memory location of myInt (remember the address-of operator!) and the value of myPointer. Print the value of myInt and the value pointed to by myPointer (remember the dereference operator!)Segmentation: Select all of the following statements that are true. In segmentation, a logical address always has a length of 32 bit. In order to translate logical into physical addresses, the memory management unit uses the segment part of the logical address to determine the start address in the segment table and adds the offset to this to get the physical address. In segmentation, the logical address consists of a segment part and an offset. The segment length is limited by the maximum possible segment number. When applying segmentation, processes are only allowed to access the memory within their segments. Segments can be assigned access rights and privilege levels.C++/CPP Exercise:1- Define a class student with the following fields:a. First nameb. Last namec. IDd. Number of courses enrolled ine.
