Question

Write a C# program that display multiplication tables.
The program lets the user input a number from a text box, then the user clicks "Show" button, then the multiplication table of the input number will be printed out, from 1 to 9, line by line in a output label. A check box called "Reverse" will be provided. If the check box is checked, the the multiplication table will be printed in reverse order (from 9 to 1). You MUST use "for loop" to create multiplication table.

Example: If the user input 3 and Reverse check box is/isn't checked, then the final result will be displayed as follows:

Not checked

Checked

3 x 1 = 3

3 x 9 = 27

3 x 2 = 6

3 x 8 = 24

3 x 3 = 9

3 x 7 = 21

3 x 4 = 12

3 x 6 = 18

3 x 5 = 15

3 x 5 = 15

3 x 6 = 18

3 x 4 = 12

3 x 7 = 21

3 x 3 = 9

3 x 8 = 24

3 x 2 = 6

3 x 9 = 27

3 x 1 = 3

Not checked

Checked

3 x 1 = 3

3 x 9 = 27

3 x 2 = 6

3 x 8 = 24

3 x 3 = 9

3 x 7 = 21

3 x 4 = 12

3 x 6 = 18

3 x 5 = 15

3 x 5 = 15

3 x 6 = 18

3 x 4 = 12

3 x 7 = 21

3 x 3 = 9

3 x 8 = 24

3 x 2 = 6

3 x 9 = 27

3 x 1 = 3

Explanation / Answer

/*
* C# Program to Find and display the Multiplication Table
*/
using System;
class Multipication
{
static void Main()
{
int no;

Console.Write("Enter a no : ");
no = Convert.ToInt32(Console.ReadLine());
while (no <= 0)
{
Console.WriteLine("You entered an invalid no");

Console.Write("Enter a no great than 0: ");
no = Convert.ToInt32(Console.ReadLine());
}
Console.WriteLine("Multiplication Table :");
for (int i = 1; i <= no; i++)
{
Console.WriteLine(" ");

for (int j = 1; j <= no; j++)
{
Console.Write("{0,6}", i * j);
}

}
Console.Read();
}
}

Output

Here is the output of the C# Program:

Enter a No : 5
Multiplication Table :
1 2 3 4 5
2 4 6 8 10
3 6 9 12 15
4 8 12 16 20
5 10 15 20 25
