- Write a C program that does a large number of references to elements of two-dimensioned arrays, using only subscripting. Write a second program that does the same operations but uses pointers and pointer arithmetic for the storage-mapping function to do the array references. Compare the time efficiency of the two programs. Which of the two programs is likely to be more reliable? Why?Someone tries to fix the stack based buffer overflow problem as follows, is it secure now? why?why not? Are there any other issues within the function's implementation below? Please explain your reasoning. int bof(char *str, int size) { char *buffer = (char *) malloc(size); strcpy(buffer, str); return 1; }I'm having a hard time seeing the problem with this buffer overflow problem can someone please elaborate if its secure or not, and if there are any other issues with the implementation in the problem? Someone tries to fix the stack based buffer overflow problem as follows, is it secure now? why? Are there any other issues within the function's implementation below? Explain your reasoning. int bof(char *str, int size) { char *buffer = (char *) malloc(size); strcpy(buffer, str); return 1; }

You're given a task to solve. Duplicating a shared pointer copies its objects, right? ExplainIn C++, how simple is it to duplicate an array of shared pointers into a new array? Create a list of potential solutions to the issue at hand. Do the objects controlled by a shared pointer also get copied when it's copied? Explain
- Q2. Consider a valid double pointer char** mypointer in a 32-bit system. What is sizeof(*mypointer)?Suppose you have the following C++ code: int* average; // Defines int pointer variables int* gradesArray; Show the single line of C++ code that creates a new int variable and store its address into average. Show the single line of C++ code that creates an eight-element array and stores the base address of the array into gradesArray. Using the example, show the lines of C++ code that deallocate the dynamic data.How can one simply copy a collection of shared pointers into another array using the C++ programming language? Create a list of potential answers to the problems you've been presented with in this scenario. Is it true that when shared pointers are copied, the objects they control are likewise copied along with them? Explain
- C++ By defining a dynamic allocation for pointer array, ask the user to enter some numbers and then return a sorted list of those numbers.Demonstrate how the gdb debugger can be utilized in aiding the establishment of Pointer assignment error language： C Perform debugging in Ubuntu Linux 16, i.e. Use only the gdb debugger. give the following screenshots：1code 2load program to gdb 3set break point 4fixed code 5load proggram ingdb again with fixed codeIn C program A set of integers 0..MAX may be implemented using an array of boolean values. This particular implementation is called a bit-vector implementation of a Set. Since C doesn’t have the Boolean data type, then substitute TRUE with 1 and FALSE with 0, or define 1 and 0 as TRUE and FALSE, respectively. For example, if the integer 3 is an element of the set, then the array element indexed by 3 is TRUE. On the other hand, if 3 is not an element, then the array element indexed by 3 is FALSE. Implement a programmer-defined data type called BitSet to represent a set as follows: typedef int BitSet[MAX]; Implement the following functions: void initialize(BitSet s); - set all array elements to FALSE void add(int elem,BitSet s); - set the item indexed by elem to TRUE void display(BitSet s); - display the set on the screen using set notation, e.g. {3,4,5,6} - this means that you will print the index value if the content of that cell is TRUE void getUnion(BitSet result,BitSet s1,BitSet…
