#include

using namespace std;

int main()

{
int n;

int row=1;

cout<<“enter the no of rows”;

cin>>n;

for(;row<=n;)

{
int col=1;

int x=row;

	for(;n-row>0;)
	{
		cout<<" ";
		row=row+1;
	}
	
	for(;col<=row;)
	{
		cout<<x;
		x=x+1;
		col=col+1;
	}
	
	for(;x>1;)
	{
		x=x-1
		cout<<x;
	}
	row=row+1;
	cout<<endl;



}
return 0;

}
but why my output is not correct pls tell

Hey @dhruvk3k your output is not correct because you are not keeping spaces in your code as the resultant output will be in shape of pyramid. Moreover the logic you have used is also not correct as you are not printing the required numbers
The hint is that if your n is 6
Then in your 6th row, you will print 6 7 8 9 10 11 10 9 8 7 6
That means 2x6-1, 11 columns in which last digit is occupied by 6 number and middle 9 digits are filled by first filling increasing digits and then decreasing digits.
Take this code for reference as it will help you to understand the implementation since I have added few comments too for better understanding


Hope this would help you :slight_smile:
