Write a Dart program to check two given integers and return true if one is negative and one is positive

Sample Output:
Input first integer:
-5
Input second integer:
25
Check if one is negative and one is positive:
True

Code:

import 'dart:io';

void main() {
  stdout.write('Input first Number : ');
  int num1 = int.parse(stdin.readLineSync());
  stdout.write('Input Second Number : ');
  int num2 = int.parse(stdin.readLineSync());

  if (num1 != 0 && num2 != 0) {
    print(true);
  }
}

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 ( 'fahrenheit = '  + fahrenheit. toString ()); } Output:
