Questions[if]

my question originated when trying to compare 2 words of different origin, one from phpmyadmin and another from excel, which visually looked exact but when executed it gave false

the difference can be seen in sublime

but then in what case is 160 used and in what others is 32

It often happens to me that I have errors when doing if-else, I don't know when to put semicolons or when to use curly braces.

What is the way to write a if-elif-elsecorrect in Awk?

I'm working with Ionic 3. When I change the value of a variable in a component, it doesn't update the view on a page where it's embedded.

I've looked at many answers to similar questions but I can't figure out how to do it.

My code is this:

PAGE: home.html

<div *ngIf="getLoading()" text-center>
<img src="http://spcdn1.whichairline.com/1c40c0f0542d7227719eccd99bd71fd172d36e0a/images/loaders/loader-search.gif">
<h1><span>Loading...</span></h1></div>
<component-myList></component-myList>

home.ts

constructor(
public navCtrl: NavController,
public myList: myListComponent) {}

public getLoading() {
  return this.myList.loading;
}

COMPONENT: myList.ts

    @Component({
       selector: 'component-myList',
       templateUrl: 'myList.html'
    })



export class myListComponent {

  public loading: boolean = false;

  constructor() {}

  putLoading() {
    this.loading = !this.loading;
    console.log(this.loading);
  }
}

myList.html

<button color="secondary" (click)="putLoading()" ion-button right>Put Loading</button>

When I press the button nothing happens, that is, the home div is not shown, although the value does change on the console.

Any ideas?

I have that question of how it works ifin low level programming.

If so, it checks the RAM by going through all the addresses that contain it.
