How to print Left Half Pyramid Pattern in Dart - Step by Step Examples

How to print Left Half Pyramid Pattern in Dart ?

Answer

To print the Left Half Pyramid Pattern in Dart, we use nested loops where the outer loop controls the rows and the inner loop prints spaces and stars.

✐ Examples

1 Left Half Pyramid Pattern

In this example,

We define the size of the pyramid, n, which is set to 5 in this example.
We use two nested loops: an outer loop to handle rows and an inner loop to print spaces and stars.
The outer loop runs from 1 to n, controlling the number of rows.
The inner loop in Dart prints spaces based on the difference between n and the current row, followed by stars equal to the current row number.
This combination of loops and print statements creates the Left Half Pyramid Pattern.

Dart Program

void printLeftHalfPyramid() {
  int n = 5;
  for (int i = 1; i <= n; i++) {
    String row = '';
    for (int j = 1; j <= n - i; j++) {
      row += ' ';
    }
    for (int k = 1; k <= i; k++) {
      row += '*';
    }
    print(row);
  }
}

void main() {
  printLeftHalfPyramid();
}
