C++ Exercises: Display specified pattern for n number of rows using number
C++ For Loop: Exercise-55 with Solution
Write a program in C++ to display such a pattern for n number of rows using numbers. There will be odd numbers in each row. The first and last number of each row will be 1 and the middle column will be the row number. N numbers of columns will appear in the 1st row.
Input number of rows: 7 1234567654321 12345654321 123454321 1234321 12321 121 1
Pictorial Presentation:

Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
int main()
{
int i,j,n;
cout << "\n\n Display a pattern using odd number of numbers, the n numbers of columns will appear in 1st row:\n";
cout << "----------------------------------------------------------------------------------------------------\n";
cout << " Input number of rows: ";
cin >> n;
for(i=n;i>=1;i--)
{
/* print blank spaces */
for(j=1;j<=n+5-i;j++)
cout<<" ";
/* Display number in ascending order upto middle*/
for(j=1;j<=i;j++)
cout<<j;
/* Display number in reverse order after middle */
for(j=i-1;j>=1;j--)
cout<<j;
cout<<endl;
}
}
Sample Output:
Display a pattern using odd number of numbers, the n numbers of column s will appear in 1st row: ----------------------------------------------------------------------- ----------------------------- Input number of rows: 7 1234567654321 12345654321 123454321 1234321 12321 121 1
