PEP/9 Translate the following C++ program into assembly language: #include <iostream> using namespace std; int main() { char letter; int countA = 0, countB = 0, countC = 0; cin >> letter; do { switch (letter) { case 'A' : countA++; break; case 'B' : countB++; break; case 'C' : countC++; break; } cin >> letter; } while (letter != 'X'); cout << "Number of A's " << countA << endl << "Number of B's " << countB << endl << "Number of C's " << countC << endl; return 0; } Use local variables (except for messages, of course) and the branch indexed for the switch statement.
Code in C Code in the file IO: /************************************************************* This program prints a degree-to-radian table using a for- loop structure. The results are printed to a file and the the screen. *************************************************************/ #include <stdio.h> #define PI 3.141593 #define FILENAME "tableD2R.dat" int main(void) { /* Declare variables. */ double radians; FILE *fileout; /* Open file. */ fileout = fopen(FILENAME,"w"); if (fileout == NULL) printf("Error opening input file. \n"); else { /* Print radians and degrees in a loop. */ printf("Degrees to Radians \n"); for (int degrees=0; degrees<=360; degrees+=10) { radians = degrees*PI/180; printf("%6i %9.6f \n",degrees,radians); fprintf(fileout,"%6i %9.6f \n",degrees,radians); } /* Exit program. */ }
Complete the missing code then compile, debug and test your program using the command lines below: c++ -o project1 project1.cpp <enter> ./project1 n m k <enter> Where n is the size of the stack, m is the modular of the real part and imagination part of a random complex number, and k is the number of elements displayed per line. In the main function, you need to Get the values n, m, and k from the command line. Declare a complex number stack of size n, generate n random complex numbers and push them into the stack. Meantime display all these numbers, k numbers per line. Display all elements of the stack, k elements per line. Create two random complex numbers c1 and c2, display c1, c2 and the results of the addition c1+c2, the subtraction c1-c2, the multiplication c1*c2, and the division c1/c2. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; class Complex {…

I need a unique solution for the following question: Note: please use stack in C language. In this project you will implement a program that simulates a simple text editor with the undo/redo functionalities allowed. The program will accept statements, one at a time with a maximum of 100 characters per line.There will be some special commands as follows:1. undo: this will undo (i.e., remove) that last entered statement;2. redo: this will redo (i.e., re-add) that last removed statement;3. print: this command will print the entire stored input text;4. save: will save the text to a file called (output.txt);5. quit: will exit the program and save all results to output.txtExecution example:MyCommand > This is a test inputMyCommand > COMP2421 – Data structures & AlgorithmsMyCommand > test1MyCommand > printresult > This is a test inputCOMP2421 – Data structures & Algorithmstest1MyCommand > undoresult > This is a test inputCOMP2421 – Data structures &…
1] Write a simple C/C++ program that shows that C/C++ does not check the index range for static one-dimensional arrays, and briefly explain how the program is supposed to check it. 2] Write a simple program in Python to detect whether the scoping of variables is static or dynamic, and briefly explain how the program is supposed to check it.
Write three functions in C or C+: one that declares a large array statically, one that declares the same large array on the stack, and one that creates the same large array from the heap. Call each subprogram a large number of times (at least 100,000) and output the time required by each. Explain the results.
In c++ write VM translator in which it will read a program written in HACK vm from an external file and ultimatley translate each line of code into Hack asm (assembly) , so, Higher level Hack Virtual machine language to Hack level assembly language. For example make it possible to translate the following: One Arithmetic (SUB), one logic (AND), and then Memory access command POP.
Write a C program that includes the following: Has 2 functions: main and swap. swap will receive two integer pointers and swap the integer values using these pointers main will have 2 integers a = 5 and b = 2 main will call swap so that a becomes 2 and b becomes 5 main will display the value of a and b both before and after the swap.
