Video Addendum

Assignment

• Work through the memory tables for both of your past assignments from Lesson01.
• For each of the code samples below:
  1. DO NOT RUN THE CODE YET
  2. Work through the memory table.
  3. Write what your program is doing in a sentence.
  4. Write what you think the program will output in console.
  5. Run the code in a new Repl to check your memory tables & outputs.
• Create a new Repl where you request 2 numbers from the user, and then display their sum.

Sample 0

#include <iostream>

int main() {
  int first = 100;
  int second = 2450;
  float third = 100.0;
  std::cout << "First number is: " << first << std::endl;
  std::cout << "Second number is: " << second << std::endl;
  std::cout << "Third number is: " << third << std::endl;

  first = first + second * 2;
  second = second + 50;
  third = third / second;
  std::cout << "First number is: " << first << std::endl;
  std::cout << "Second number is: " << second << std::endl;
  std::cout << "Third number is: " << third << std::endl;
  
  first = second / first;
  third = first / third;
  std::cout << "First number is: " << first << std::endl;
  std::cout << "Second number is: " << second << std::endl;
  std::cout << "Third number is: " << third << std::endl;
}

Sample 1

#include <iostream>

int main() {
  std::cout << "Enter a number: ";
  int first = 100;
  
  std::cin >> first;
  int second = 2450;
  float third = 100.0;
  std::cout << "First number is: " << first << std::endl;
  std::cout << "Second number is: " << second << std::endl;
  std::cout << "Third number is: " << third << std::endl;

  first = first + second * 2;
  second = second + 50;
  third = third / second;
  std::cout << "First number is: " << first << std::endl;
  std::cout << "Second number is: " << second << std::endl;
  std::cout << "Third number is: " << third << std::endl;
  
  first = second / first;
  third = first / third;
  std::cout << "First number is: " << first << std::endl;
  std::cout << "Second number is: " << second << std::endl;
  std::cout << "Third number is: " << third << std::endl;
}
