Write a Dart Program that takes a number as input and then displays a rectangle of 3 columns wide and 5 rows tall using that digit

Enter a number: 5
Expected Output:
555
5 5
5 5
5 5
555

Code:

import 'dart:io';

void main() {
  stdout.write('Input Number : ');
  int x = int.parse(stdin.readLineSync());

  for (int i = 0; i < 5; i++) {
    for (int j = 0; j < 3; j++) {
      if (j % 2 == 0 || i == 0 || i == 4) {
        stdout.write(x);
      } else {
        stdout.write(' ');
      }
    }
    print('');
  }
}

Write a Dart program to convert from celsius degrees to Kelvin and Fahrenheit.

Image
Test Data: Enter the amount of celsius: 30 Expected Output: Kelvin = 303 Fahrenheit = 86 Conversion Values. Kelvin to Celsius : C = K - 273 (C = K - 273.15 if you want to be more precise) Kelvin to Fahrenheit : F = 9/5(K - 273) + 32 or F = 1.8(K - 273) + 32 Celsius to Fahrenheit : F = 9/5(C) + 32 or F = 1.80(C) + 32 Celsius to Kelvin : K = C + 273 (or K = C + 271.15 to be more precise) Fahrenheit to Celsius : C = (F - 32)/1.80 Fahrenheit to Kelvin : K = 5/9(F - 32) + 273.15 Code: import   'dart:io' ; void   main () {   stdout. write ( 'Input Temperature in celsius : ' );    int  celsius =  int . parse (stdin. readLineSync ());    double  kelvin = celsius. toDouble () +  273.0 ;    double  fahrenheit = (celsius *  1.80 ) +  32 ;    print ( 'Kelvin = '  + kelvin. toString ());    print ( 'fahrenhe...
