Create a program that makes a multiplication table. Ask the user how many number

Question

Create a program that makes a multiplication table. Ask the user how many numbers should be in the table.

Requirements
Store all of the data in a 2-dimensional vector of ints.
Allow the program to run repeatedly until the user is finished.
Do not allow inputs outside the range of 1-9

Sample Run
Enter the numbers for multiplication table (1-9): -1


Enter the numbers for multiplication table (1-9): 10


Enter the numbers for multiplication table (1-9): 4


| 1 2 3 4
- | - - - -
1 | 1 2 3 4
2 | 2 4 6 8
3 | 3 6 9 12
4 | 4 8 12 16

| 4 3 2 1
- | - - - -
4 | 16 12 8 4
3 | 12 9 6 3
2 | 8 6 4 2
1 | 4 3 2 1

Do you want to do another? (y/n) y

Enter the numbers for multiplication table (1-9): 3


| 1 2 3
- | - - -
1 | 1 2 3
2 | 2 4 6
3 | 3 6 9

| 3 2 1
- | - - -
3 | 9 6 3
2 | 6 4 2
1 | 3 2 1

Do you want to do another? (y/n) n

Things to Consider

You can use setw(n) before any number and it will add blank spaces to show the number in n columns. That is how to line up your columns.
Don't forget you have 0 based indexes and numbers that go from 1 to 9.

Explanation / Answer

#include<iostream.h>

void main()
{
   int n,i,j,a[9][9];
   char ans='y';

   while(ans=='y')
   {
       cout<<"enter number for multiplication table [1-9]";
       cin>>n;
       if(n>1 && n<=9)
       {

           for(i=0;i<n;i++)
           {
               for(j=0;j<n;j++)
               {
                   a[i][j]=(i+1)*(j+1);
               }
           }

           for(i=0;i<n;i++)
           {
               for(j=0;j<n;j++)
               {
                   cout<<a[i][j]<<" ";
               }
               cout<<" ";
           }
       }
       cout<<"Do you want to continue [y/n]";
       cin>>ans;
   }
}
