How to make If statement in loop only run once

i have three if statements and when i write a number it runs infinitetly even tho its if

using System;
using System.Runtime.InteropServices;

namespace Guessing_game
{
    internal class Program
    {
        static void Main(string[] args)
        {
         Random rnd = new Random();
        int num = rnd.Next(1, 100);
        Console.WriteLine(num);
        Console.WriteLine("Guess the number");
        string Guess = Console.ReadLine();

        int IntGuess = int.Parse(Guess);

            Console.WriteLine(IntGuess);

            int on = 0;

            while (on < 1)
            {
                if (num > IntGuess)
                {
                    Console.WriteLine("Higher");
                }

                if (num < IntGuess)
                {
                    Console.WriteLine("Lower");
                }

                if (num == IntGuess)
                {
                    Console.WriteLine("Good job");

                }
            }
        }
    }
}

using System;
using System.Runtime.InteropServices;

namespace Guessing_game
{
    internal class Program
    {
        static void Main(string[] args)
        {
         Random rnd = new Random();
        int num = rnd.Next(1, 100);
        Console.WriteLine(num);
        Console.WriteLine("Guess the number");
        string Guess = Console.ReadLine();

        int IntGuess = int.Parse(Guess);

            Console.WriteLine(IntGuess);

            int on = 0;

            while (on < 1)
            {
                if (num > IntGuess)
                {
                    Console.WriteLine("Higher");
                }

                if (num < IntGuess)
                {
                    Console.WriteLine("Lower");
                }

                if (num == IntGuess)
                {
                    Console.WriteLine("Good job");

                }
            }
        }
    }
}

its your while statement that is running infinitely

Cheetah•12mo ago

ok so how do i make it so it doesnt run infinitly but the code doesnt end after one input

Jimmacle•12mo ago

you need to put everything that you want to repeat inside the while loop right now your loop runs forever because the value of on never changes inside it

SinFluxx•12mo ago

well you've set the condition for it to run while (on < 1) so you need to make that condition false once you're finished

Cheetah•12mo ago

ok but like

SinFluxx•12mo ago

like @jimmacle said as well all the relevant code needs to be inside your while loop as well (i.e. where you're getting the guess from the user)

Cheetah•12mo ago

i want it to run once every time i write something

Jimmacle•12mo ago

but you want to write something multiple times?

Cheetah•12mo ago

yes i wanna make a guessing game

Jimmacle•12mo ago

if you only want something to run once just don't put it in its own loop put the entire process that you want to repeat in there so if you want to guess numbers until you get it right, you probably want your loop to include asking for guesses

Cheetah•12mo ago

what_ i dont understand

Jimmacle•12mo ago

which part is confusing?

SinFluxx•12mo ago

if the user's guess is wrong you need to ask them for another number?

Cheetah•12mo ago

if the users guess is wrong it says higher or lower depending on if the correct number is higher or lower

Jimmacle•12mo ago

right, then what?

Cheetah•12mo ago

and u just do that until you guess the number but it keeps saying higher many times

Jimmacle•12mo ago

do that until you guess the number

"that" is what should be in the loop right, walk through your code and see if you can figure out why that's happening

Cheetah•12mo ago

its running the same thing multiple times but idk how to make it run only once

Jimmacle•12mo ago

but you don't want it to only run once, you're just looping around the wrong things you want something to run until they guess the right number, right?

Cheetah•12mo ago

yes

Jimmacle•12mo ago

so all those things should be put in the loop

Cheetah•12mo ago

so i add more of the code to the loop??

SinFluxx•12mo ago

yes, think about what you need to repeat you ask me to guess a number I give you a number you tell me it's wrong then...?

Cheetah•12mo ago

aight thank you fixed it
