In the stuff I did below, everything is fine but:
Console.WriteLine("You are a child");
(and all the other ones similar to this^) say there is an error after the semicolon

C#

namespace B13
{
    class Program
    {
        static void Main(string[] args)
        {
            int age = 1;
            while (age >= 50)

            {
                Console.WriteLine("Enter your age");


                age = Convert.ToInt32(Console.ReadLine());
                {

                    if (age > 29)
                    {
                        do


                            Console.WriteLine("You are old!");
                    }
                    else
                    {
                        if (age == 19)
                            while (age != 30)
                                do
                                    Console.WriteLine("You are getting old");




                     else
                        {
                            if (age == 13)
                                while (age != 19)
                                    do
                                        Console.WriteLine("You are a teenager");


                       else
                            {
                                if (age < 13)

                                    do
                                        Console.WriteLine("You are a child");
                    }
                            Console.WriteLine(age);
                            Console.ReadKey();


                        }
                    }
                }
            }
        }
    }
}

What I have tried:

The following will compile, but the code has semantic issues:
If you enter age of 19, or 13 it will loop forever. Inputs 14,15,16,17,18 will print nothing. I don't think you want to use while. Probably you want something like
if (age >=14 and age <= 19) Console.WriteLine("You are a teenager");

C#

using System;

namespace B13
{
    class Program
    {
        static void Main(string[] args)
        {
            int age = 1;
            while (age >= 50)

            {
                Console.WriteLine("Enter your age");

                age = Convert.ToInt32(Console.ReadLine());
                {
                    if (age > 29)
                    {
                        Console.WriteLine("You are old!");
                    }
                    else
                    {
                        if (age == 19) while (age != 30) Console.WriteLine("You are getting old");

                        else
                        {
                            if (age == 13) while (age != 19) Console.WriteLine("You are a teenager");

                            else
                            {
                                if (age < 13) Console.WriteLine("You are a child");
                            }
                            Console.WriteLine(age);
                            Console.ReadKey();
                        }
                    }
                }
            }
        }
    }
}

Solution 2

What are supposed to be all those while and do scattered everywhere?
Those are not random statements!

Your code is very confuse, you should tell us what is supposed to do your code.
