• Operators

    Logical operators in programming are like a set of tools that help us decide what to do depending on how things look. Logical operators tell the computer to do something based on how two different things compare.

      • Increment Operators

      • The increment operator increments the value of a single variable.

      • Dart

        Example of increment operator in dart.
        void main() {
  var age = 20;

  // Increment After
  print(age++); // 20
  print(age); // 21

  // Increment Before
  print(++age); // 22
  print(age); // 22
}

      • Decrement Operators

      • The decrement operator decrements the value of a single variable.

      • Dart

        Example of decrement operator in dart.
        void main() {
  var age = 20;

  print(--age); // 18
  print(age); // 18
}
