C#階乘問(wèn)題
計(jì)算階乘.比如用戶在TextBox里輸入7,就會(huì)顯示 ：
The factorial of 1 is 1
The factorial of 2 is 2
The factorial of 3 is 6
The factorial of 4 is 24
The factorial of 5 is 120
The factorial of 6 is 720
The factorial of 7 is 5040
.
這是我的代碼,這是乘方,怎么寫階乘?
//Declare variables
int numRow =0;
int i = 0;
public calculateButton()
{
InitializeComponent();
}
private void buttonCalculate_Click(object sender,EventArgs e)
{
if (int.TryParse(textBoxnumber.Text,out numRow) == true)
{
for (int i = 1; i
