Simple Programs

Let's see the simple example of printing 1 to 10 numbers using respective languages.

Program in C

#include<stdio.h> 
int main() 
{
    int i=1;
    do
    {
        printf("%d ",i);
        i++;
    }while(i<=10);
    return 0;
}

In this program, the value of i is 1. The "do-while" loop is used in this program to print the numbers from 1 to 10 using printf() function.

Program in C++

#include<iostream>
using namespace std;
int main()
{
    int i=1;
    do
    {
     std::cout <<i<<" ";
        i++;
    }while(i<=10);
    return 0;
}

In this program, i contains the value 1. The do while loop is used to print the numbers from 1 to 10 using cout object.

Program in C#

using System;
namespace Rextester
{
    public class Program
    {
        public static void Main(string[] args)
        {
            int i=1;
            do{
            Console.Write(i);
               Console.Write(" ");
                i++;
            }while(i<=10);
        } }} 

In this example, i contains the value 1. The do-while loop is used in this program to print the numbers from 1 to 10 using Console.Write().

Program in Java

public class HelloWorld{
  public static void main(String []args){
        int i=1;
        do
        {
            System.out.print(i);
            System.out.print(" ");
            i++;
        }while(i<=10);
        
     }
}

In this example, i contains the value 1. The do-while loop is used in this program to print the numbers from 1 to 10 using System.out.print().

Program in JavaScript

<script>
var i=1;
do
{
document.write(i);
document.write(" ");
i++;
}while(i<=10)
</script>
</p>

In this program, variable i contains the value 1. The do while loop is used in this program to print 1 to 10 numbers using document.write() funtion.

Program in Perl

$i=1;
do
{
    printf("$i");
    printf(" ");
    $i=$i+1;
}while($i<=10);

In this program, $i contains the value 1 and printf() function is used to print the numbers from 1 to 10.

Program in PHP

<?php //php 7.0.8
 $i=1;
do{
    echo $i;
    echo " ";
    $i=$i+1;
}while($i<=10);
?>

In this program, $i contains the value 1 and an echo statement is used to print the values of i.

Program in Ruby

$i=1;
loop do
print $i;
 $i=$i+1;   
break if($i>10) 
 end

In this program, ruby contains "do if" block. This loop opposes the "if-condition" i.e the i>10. Therefore, the loop is executed till i=10. When, i becomes 11, control terminates the loop.

Program in Swift

var i=1
repeat{
    print ("\(i)")
    i=i+1;
    }while(i<=10)

In this program, variable i contains the value 1.The "repeat -while" loop is executed till i=10. When i becomes 11, it leads to the termination of a loop.

Output:

1 2 3 4 5 6 7 8 9 10
