#System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

skshetry

#include "stack.hpp"
//////////////////////////////////   This is an implementation file ///////////////////////////////////////////////////////
/////////////////////////////////    How to use this in your code? ///////////////////////////////////////////////////////
/*
   First include "stack.hpp> in your source file at the top.
   1. g++ -o <outputbinaryfilename> <yourfilename> stack.cpp
   2. g++ -o stack.o -c stack.cpp
      g++ -o main.o -c <yourfilename>
      g++ -o main.o stack.o
*/

skshetry

#include "lib/stack.hpp"
#include <iostream>
#include <string>
#include <cstring>
#include <algorithm>
#include <cctype>

using std::string;
using std::cin;
using std::cout;

skshetry

#include <iostream>
using namespace std;

class Queue{
    int data[1000];
    int rear_pointer = -1;
public:
    void enqueue(int incomindata){
        data[++rear_pointer] = incomindata;
    }
