I'm making a menu type of all kinds of sorting algorithm. the user will input ten numbers in the TextBox, select a RadioButton, then click the generate button. the output must show each line on how the algorithm works.
(Selection Sort)
sample input from TextBox: 9 6 8 7 5 2 3 1 10 4
output:
1 6 8 7 5 2 3 9 10 4 \n
1 2 8 7 5 6 3 9 10 4 \n
1 2 3 7 5 6 8 9 10 4 \n
1 2 3 4 5 6 8 9 10 7 \n
1 2 3 4 5 6 7 9 10 8 \n
1 2 3 4 5 6 7 8 10 9 \n
1 2 3 4 5 6 7 8 9 10 \n
I made a program like these on Java, but I only used JOptionPane. I do not have any ideas on how to convert it to c# and by using TextBox and RichTextBox.
Here's my codes so far. My output always show a lot of zeros.
int[] nums = new int[10];
int i, s, min, temp;
private void EnterNum_TextChanged(object sender, EventArgs e)
{
string[] nums = EnterNum.Text.Split(' ');
//int[] nums = new int[] { int.Parse(EnterNum.Text) };
}
private void GenerateButton_Click(object sender, EventArgs e)
{
if (SelectionRadio.Checked == true)
{
for (i = 0; i < nums.Length - 1; i++)
{
min = i;
// In each iteration, find the smallest number
for (s = i + 1; s < nums.Length; s++)
{
if (nums[min] > nums[s])
{
min = s;
}
}
if (min != i)
{
temp = nums[i];
nums[i] = nums[min];
nums[min] = temp;
}
Display();
}
}
Display();
}
private void ClearButton_Click(object sender, EventArgs e)
{
richTextBox1.Clear();
}
public void Display()
{
int i;
String numbers = "";
for (i = 0; i < 10; i++)
numbers += Convert.ToInt32(nums[i]).ToString() + " ";
richTextBox1.AppendText(numbers);
}
before starting algorithm you need to fill your nums
array from textbox, you see zeros because by default array is filled with zeros and you just displaying default array:
string[] numsInString = EnterNum.Text.Split(' ');
nums = new int[numsInString.Length];
for (int j = 0; j < numsInString.Length; j++)
{
nums[j] = int.Parse(numsInString[j]);
}
if (SelectionRadio.Checked == true)
//...
and to display nicely add "\\n" when appending text:
richTextBox1.AppendText(numbers+"\n");
also as Matt mentioned use .ToString()
, your nums
are integers already so you dont need to convert int
to int
:
numbers += nums[i].ToString() + " ";
