In this tutorials will teach How to do the student mark calculation in Angular.

First you have to add the FormsModule inside the imports.

Create the new Components studentmarks

studentmarks.component.html

<form>

    <h1>Add Students Marks Calculation</h1>

<div>
  <label >Marks 1</label>
  <input type = "text"  name="num1" [(ngModel)] = "marks1" class="form-control"  placeholder="Enter Num 1">

</div>

  <div>
    <label >Marks 2</label>
    <input type = "text"  name="num2"  [(ngModel)] = "marks2" class="form-control"  placeholder="Enter Num 2">
  
  </div>

  <div>
    <label >Marks 3</label>
    <input type = "text"  name="num2"  [(ngModel)] = "marks3" class="form-control"  placeholder="Enter Num 2">
  
  </div>


  <div >
    <label >Total</label>
    <input  class="form-control"  placeholder="Total" value="{{ result }}"> 
  </div>

  <div >
    <label >Average</label>
    <input  class="form-control"  placeholder="Total" value="{{ avg }}"> 
  </div>

  <div *ngIf="avg > 50; else grade">

  </div>

  <ng-template #grade>
    Fail
  </ng-template>

 
<button  (click)="StudentTot()" class="btn btn-primary mt-4">Submit</button>

</form>

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-studentmarks',
  templateUrl: './studentmarks.component.html',
  styleUrls: ['./studentmarks.component.scss']
})
