Guessing Game~! by C++

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void guessGame();
bool isCorrect(int, int);
int main(){
 srand (time (0));

 guessGame();
 return 0;
}
void guessGame(){
 int answer;
 int guess;
 char response;


 do{
  answer = 1 + rand() % 10; // make constant random value from 1 to 100
  cout << "Guess number between 1 and 10" <<endl;
  cin >> guess;
   
  while( !isCorrect(guess, answer)) // as long as the return value is false, continue
   cin >> guess; // condition itself calls funtion
 
  cout << "\n Congrat!! wanna play new guess?" << endl;
  cout << " \"y\"to start \"n\" to end" << endl;
  cin >> response;
  } while (response == 'y');
 }

//isCorrect returns true if the guess is right
//if g does not equal a, displays hint
bool isCorrect(int g, int a){
 if (g == a){
  return true;
 }
 if (g < a){
  cout << "Too low.. Try again" << endl;
 }
 if (g > a){
  cout << "Too high.. Try again" << endl;
 }

 return false;

/*This semester I take c++ and JAVA class...learning coding by English is not easy...
it has been so long time to post my coding...
Actually I practiced some materials of professor making the copy of them but didn't post..don't know why
And definitely JAVA is complicated!!!!!
I got stuck doing assignment, found myself too stupid to go further and wend back to the very first meterials of class
I hope I can make improvement during left holiday....
no "wait and see" but "do it and see"....... */

JS 5.5 task6 Create an extendable calculator

<HTML>   <body>   </body>   <script> function Calculator() {   let methods = {     "-" : (a, b) => a - b,     "+" : (a, b) => a + b   };   //methods is an object which keeps key for operators   //and value to return the actual operation values   //each returns the result of operation that key(operator) does   this.calculate = function (str){     //calculate is one element in the function Calculator     //it takes the string and returns the value     //in the function element list is delimeted by , not ;     let split = str.split(" "),     a = +split[0],     op = split[1],     b = split [2]     if(!methods[op] || isNaN(a) || isNaN(b)) {       return NaN; // error handling     }     return methods[op](a,b);   }   this.addMethod = function(name, func){     methods[name] = func;     //this is how to add new key and ele to object   } } let powerCalc = new Calculator; powerCalc.addMethod("*&

JS 5.7 task5 Store read dates

<HTML>   <body>   </body>    <script>    let messages = [        {text: "Hello", from: "John"},        {text: "How goes?", from: "John"},        {text: "See you soon", from: "Alice"}    ];    let readMap = new WeakMap();    alert(readMap.size);    readMap.set(messages[0], new Date(2019, 3, 5));   </script> </HTML> <!-- task4 needed weakSet to save simply readmessage, this task needs to save THE TIME IT WAS READ along with the message itself the message out of the set or map means it hasn't been read I kinda feel good and bad at the same time to happen to read the solution but I do get to think more about the difference with tasks and be more available to understand the main contents so I think, its good? -->

How to set base url when deployed in Heroku? : base url and axios

https://stackoverflow.com/questions/47164330/axios-api-calls-in-heroku/47165888 baseUrl = process.env.baseURL || "http://localhost:5000" Even more stable way https://stackoverflow.com/questions/52129849/how-to-get-the-base-url-variable-on-a-deployed-heroku-node-app const production  = 'https://examplePage.com'; const development = 'http://localhost:3000/'; const url = (process.env.NODE_ENV ? production : development); process.env.NODE_ENV will resolve to undefined if you are running on localhost production mode. and return production if you have deployed the app production mode.
