I have tried looping this it didnt work for me please help me im trying to learn c# and it would help alot if you would help me
using System.Text.RegularExpressions;
{
Console.WriteLine("What do you want to check, if its a number or not: ");
int myInt = Convert.ToInt32(Console.ReadLine());
bool isLessThan10000000000 = myInt < 10000000000;
Console.WriteLine("Is it a Number? {0}", isLessThan10000000000);
Console.ReadKey();
Console.WriteLine("Do you want to continue (Y/N)? ");
if (Console.ReadKey().KeyChar == 'Y')
{
}
else
{
}
}
You can use a do while loop
it's about the same as a while loop expect it evaluates the condition after the loop instead of before
do
{
//Your code
}
while(Console.ReadKey().KeyChar == 'Y');

I need to write an if statement block that will run if the value entered is less than $5.65 or greater than 50. How can I do this?
using System;
using static System.Console;
namespace HomeWork1
{
internal class Program
{
static void Main(string[] args)
{
WriteLine ("What is your hourly pay rate");
double rate;
string input;
input = ReadLine();
rate =Convert.ToDouble(input);
WriteLine("Your hourly pay rate {0}", rate);
if (rate < 5.65 )
{
Console.WriteLine("Error entering your pay rate");
}
}
}
}
}
Use the or operator || to make this work. The or operator || will execute the if block if either one of the conditions are true.
if (rate < 5.65 || rate > 50)
{
Console.WriteLine("Error entering your pay rate");
}

Hi there I want to know how this kind of conditional statement means?
if (i == 0)
{
lowest = highest = input;
}
When you come across questions like this, i would recommend that you test it yourself. For instance, this can be tested in a simple console app to see what happens
class Program
{
public static void Main(string[] args)
{
int lowest = 1;
int input = 2;
int highest = 3;
Console.WriteLine("Before equality operator");
Console.WriteLine($"lowest: {lowest}");
Console.WriteLine($"highest: {highest}");
Console.WriteLine($"input: {input}");
int i = 0;
if (i == 0) lowest = highest = input;
Console.WriteLine("After equality operator");
Console.WriteLine($"lowest: {lowest}");
Console.WriteLine($"highest: {highest}");
Console.WriteLine($"input: {input}");
}
}
Output:
Before equality operator
lowest: 1
highest: 3
input: 2
After equality operator
lowest: 2
highest: 2
input: 2

I need to write a program which count sum of numbers divided by 4. I'm really beginner in C#.
Could you lead me to solve this problem?
I write something like this but I don't know what next and there is one problem because I put only two numbers but numbers could be a lot of.
Console.WriteLine("number a");
int a = int.Parse(Console.ReadLine());
Console.WriteLine("number b");
int b = int.Parse(Console.ReadLine());
int sum = a + b;
int result = sum / 4 ;
Console.WriteLine ( "result is="+ result ) ;
use
double sum = Console.ReadLine().Split().Sum(x => int.Parse(x)) / 4.0;
Than you can enter any space separated array like
1 3 5 7

I need my if statement to return an image if it is within a range. the current code does not work
if (Int32.Parse(Domain_OSUMC_IT_CHECKBOX.Text.Trim()) == 1)
{
Domain_green_Check.Visible = true;
}
else if (Int32.Parse(XP_OSUWMC_IT_LBL.Text.Trim()) >= 1 && <=.9)
{
Domain_green_Check.Visible = true;
This is where im having the trouble
else if (Int32.Parse(XP_OSUWMC_IT_LBL.Text.Trim()) >= 1 && <=.9)
I need to make the image domain_green_check visible if another label Domain_OSUMC_IT_CHCEKBOX is between the values of .9 and 1
You need to fix your syntax and conert the string to decimal
decimal val = decimal.Parse(XP_OSUWMC_IT_LBL.Text.Trim());
else if (val > .9 && val < 1) //though this condition makes nosense since it will never evaluate to TRUE

I am trying to create some code that search for a value .
As of now the code looks like :
private void button4_Click(object sender, EventArgs e)
{
uint randBuff = DLL.Extension.ReadUInt32(0x0154d6e4);
for (int i = 0; i < 144705; i++)
{
randBuff = (randBuff + 4);
listBox1.Items.Add(randBuff.ToString("x8"));
}
}
The value I search is 144705 . The idea is to stop searching for the value when randBuff =144705 . Can this be done with a loop or is there any other way to do it ?
If I understand your question right, then this is more appropriate of a loop:
while (randBuff < 144705)
{
listBox1.Items.Add(randBuff.ToString("x8"));
randBuff += 4;
}
Basically, as long randBuff is less than the target value of 144705, add the value to the list box and increase the value by 4.
