. What will be the output of the following code, consider the memory address of variable x is 0x0044c and pointer variable ptr is 0x0066f, and consider int data type take 2 byte in the memory void main() { int x[5] = { 1,2,3,4,5 }; int *ptr = x; ptr = ptr + 1; cout << ptr << endl; cout << *ptr << endl; cout << &ptr << endl; cout << &x[0] << endl; cout << *x << endl; x += 2; cout << x << endl; }
Example: The Problem Input File Using C programming language write a program that simulates a variant of the Tiny Machine Architecture. In this implementation memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the Tiny Machine Architecture: //IN 5 //OUT 7 //STORE O //IN 5 //OUT 7 //STORE 1 //LOAD O //SUB 1 55 67 30 55 67 1 LOAD 2- ADD 3> STORE 4> SUB 5> IN 6> OUT 7> END 8> JMP 9> SKIPZ 31 10 41 30 //STORE O 67 //OUT 7 11 /LOAD 1 //OUT 7 //END 67 70 Output Specifications Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Memory Address Registers, Instruction Memory, Data Memory, Memory Data Registers, and Accumulator). Data Memory will be represented by an integer array. Your Program Counter will begin pointing to the first instruction of the program. Your simulator should provide output according to the input file. Along with…
Translate the following C++ program to Pep/9 assembly language. Code should also be commented. #include <iostream>using namespace std;int Lesser(int x, int y) { int least; if (x < y) least = x; else least = y; return least;}int main(){ int num1; int num2; cout << "Enter two integers: "; cin >> num1 >> num2 cout << "Lesser: " << Lesser(num1, num2); << endl; return 0;}
The program below uses pointer arithmetic to determine the size of a 'char'variable. By using pointer arithmetic we can find out the value of 'cp' and thevalue of 'cp+1'. Since cp is a pointer, this addition involves pointer arithmetic:adding one to a pointer makes the pointer point to the next element of the sametype.For a pointer to a char, adding 1 really just means adding 1 to the address, butthis is only because each char is 1 byte.1. Compile and run the program and see what it does.2. Write some code that does pointer arithmetic with a pointer to an int anddetermine how big an int is.3. Same idea – figure out how big a double is, by using pointer arithmetic andprinting out the value of the pointer before and after adding 1.4. What should happen if you added 2 to the pointers from exercises 1through 3, instead of 1? Use your program to verify your answer.#include <stdio.h>int main( ){ char c = 'Z'; char *cp = &c; printf("cp is %p\n", cp); printf("The character at cp is…

Security: 1. Buffer overflow A C code example for Buffer Overflow is below: #include #define BUFFER SIZE 256 int main(int argc, char *argv[]) { char buffer[BUFFER SIZE]; if (argc <2) return -1; else { } strcpy(buffer,argv[1]); return 0; } (a) Explain the C code here on what it is doing. (b) Explain why buffer overflow may happen (c) Explain how you can modify the code to avoid buffer overflow.
F Convert the following C++ program into assembly language. int table[10]; void get(int &x ) { cout > X; } int main() { int total = 0; int i; for (i = 0; i <10; i++) { get( table[i]); total = total + table[i]; } cout << total << endl; }
// Example 8.27b void Func(int a[], int & r) { int i; int induction = r; for (i = 0; i < 100; i += 2) { a[i] = induction; a[i+1] = induction; induction++; }}Write the assembly code generated by the assembler from example 8.27b.
Write a program in C++ language to illustrates how a pointer variable works. Follow the instruction below; - Create main function and include your information details - Declare the pointer variable of p as an integer - Declare an integer variable of num1 and num2, and set the value of num1 = 5 and num2 = 8 - Store the address of num1 into p - Print the address of &num1 and value of p - Print the value of num1 and *p - Change the value of *p to 10 - Print the value of num1 and *p - Store the address of num2 into p - Print the address of &num2 and value of p - Print the value of num2 and *p - Multiply the value of *p by 2 - Print the value of num2 and *p
In C++, please explain in detail Declare an integer variable XYZ and a pointer called XYZpointer. Write the C++ statemens that will correcty make pointer variable XYZpointer point to the storage location XYZ and extract its address.
