C++ Exercises: Display such a pattern for n number of rows using number
C++: For Loop Exercise-47 with Solution
Write a program in C++ to display such a pattern for n number of rows using numbers. Odd numbers will appear in each row. The first and last number of each row will be 1 and the middle column will be the row number.
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 first and last number of each row is 1:\n";
cout << "-----------------------------------------------------------------------------------------------\n";
cout << " Input number of rows: ";
cin >> n;
for(i=0;i<=n;i++)
{
/* print blank spaces */
for(j=1;j<=n-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 first and last number of each row is 1: ----------------------------------------------------------------------------------------------- Input number of rows: 5 1 121 12321 1234321 123454321
