Given this Angular component code snippet, what will be displayed?
@Component({ standalone: true, selector: 'app-counter', template: `<button (click)='count = count + 1'>Increment</button><p>Count: {{count}}</p>` }) export class CounterComponent { count = 0; }
ASyntax error due to missing imports
BA button labeled 'Increment' but the count never changes
CA button labeled 'Increment' and a paragraph showing 'Count: 0' initially, increasing on clicks
DNothing is displayed because count is not initialized
Step-by-Step Solution
Solution:
  1. Step 1: Analyze component behavior

    The component has a count variable starting at 0 and a button that increments count on click.
  2. Step 2: Understand template binding

    The template shows the count value and updates it when the button is clicked.
  3. Final Answer:

    A button labeled 'Increment' and a paragraph showing 'Count: 0' initially, increasing on clicks -> Option C
  4. Quick Check:

    Button click updates count = A [OK]
Quick Trick: Click updates count variable shown in template [OK]
Common Mistakes:
  • Assuming count does not update without explicit change detection
  • Thinking missing imports cause syntax error here
  • Believing count is undefined initially
