📘 Code Example 2: Dart Variables and Printing

void main() {
  // Basic types
  int age = 21;
  double height = 5.9;
  String name = "Sharada";
  bool isStudent = true;

  // Printing
  print("Name: $name");
  print("Age: $age");
  print("Height: $height");
  print("Student: $isStudent");
}

Explanation:

• int, double, String, and bool are basic data types in Dart.
• Dart uses string interpolation ($variableName) to insert variable values into strings.
• print() is used to display output.

Output:

Name: Sharada
Age: 21
Height: 5.9
Student: true
