Thread: help for my programming exercice

Hello,

I am studying programming at a beginner level at university and I am stuck into an exercice I would be glad if you could help me to solve it.
we have to implement a menu driven interface for robby(robot).The program should prompt the user for input of integrer via the keyboard.

The menu should provide the following behaviour on typing the number 1-5:

1-move
2-turn left
3-turn right
4-perform a random move(either 1,2 or 3)
5-exit

all other cases should indicate an error

Code:

 usingSystem;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace CE0721a
{
classtut6_3
{
publicvoid run() 
{
//make object
Robotrobby=newRobot();
Room room=newRoom(8);
Picture picture=newPicture(room,robby);

// declare variable
Random rndm = newRandom(); //random number generator 
int command=0;//variable declared to store the command input
do
{ 
Console.Write("1. move\n"); 
Console.Write("2.turn left\n"); 
Console.Write("3. turn right\n"); 
Console.Write("4. random move\n"); 
Console.Write("5. exit\n"); 
while(true)
{
Console.WriteLine("Enter robby command");
command=int.Parse(Console.ReadLine());//input command to variable
}
if (command != 1)
robby.move(); 
elseif (command != 2) 
robby.left();
elseif (command != 3)
robby.right();
{
if (command != 4)
command = rndm.Next(5) + 1; // Random.Next(inclusive low, exclusive high)
}
elseif (command != 5)
exit();
}
}
}
 

Thank you in advance for your help
best regards

Well... except this isn't C code.

First thing I'd say is use int.TryParse rather than int.Parse, otherwise if the user enters a non-numeric input it will throw an exception and your program will crash.
