Else-If Ladder in Dart

The else-if ladder allows you to test multiple conditions one after another. The program executes the block of the first true condition and skips the rest.

Syntax:

if (condition1) {
  // code if condition1 is true
} else if (condition2) {
  // code if condition2 is true
} else if (condition3) {
  // code if condition3 is true
} else {
  // code if all conditions are false
}

Example:

void main() {
  int score = 72;

  if (score >= 90) {
    print('Grade: A');
  } else if (score >= 75) {
    print('Grade: B');
  } else if (score >= 60) {
    print('Grade: C');
  } else {
    print('Grade: F');
  }
}

Explanation:

• The program checks conditions in order.
• When it finds a condition that is true, it runs that block and skips the rest.
