Do While Loop Example Program in Dart

This is a Dart program that demonstrates the use of a do-while loop. The program starts by importing the dart:io library, which provides classes for reading input from the console. The next lines declare three variables i, t, and n and initialize i to the value 1.

The program then prompts the user to enter a table and a limit by printing the message 'Enter the Table and Limit : '. The user's input for the table and limit is read using the stdin.readLineSync() method and converted to integers using the int.parse() function.

The program then starts a do-while loop that executes the code inside the loop at least once and continues to do so as long as i is less than or equal to n. Inside the loop, the program prints the current value of t, i, and the result of t * i on the console using the print() function. This calculates and prints the multiplication table of t from 1 to n.

After printing the table for the current value of i, the program increments i by 1 using the expression i++. Once i is greater than n, the loop will terminate, and the program will exit.

Overall, this program demonstrates how to use a do-while loop in Dart to perform a set of instructions repeatedly and at least once as long as a certain condition is true. In this case, the program prints the multiplication table for a given number t up to a given limit n.

Source Code

//Do While loop
 /*
   * Limit 5
   * Table 2  2*1=2 2*5=10
 */
import 'dart:io';
void main() {
   var i=1,t,n;
   print('Enter the Table and Limit : ');
   t=int.parse(stdin.readLineSync());
   n=int.parse(stdin.readLineSync());
   do
   {
     print(t.toString()+'*'+i.toString()+'='+(i*t).toString());
     i++;
   }while(i<=n);
}
