1 232 34543 4567654 567898765
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
int main()
{
int i, j, spc, n;
cout << "\n\n Display the pattern like pyramid using digits:\n";
cout << "---------------------------------------------------\n";
cout << " Input the number of rows: ";
cin >> n;
for (i = 1; i <= n; i++)
{
spc = n - i;
while (spc-- > 0)
cout << " ";
for (j = i; j < 2 * i - 1; j++)
cout << j;
for (j = 2 * i - 1; j > i - 1; j--)
cout << j;
cout << endl;
}
}
Sample Output:
Display the pattern like pyramid using digits: --------------------------------------------------- Input the number of rows: 5 1 232 34543 4567654 567898765

C++ Programming: Tips of the Day
What is the "-->" operator in C/C++?
--> is not an operator. It is in fact two separate operators, -- and >.
The conditional's code decrements x, while returning x's original (not decremented) value, and then compares the original value with 0 using the > operator.
To better understand, the statement could be written as follows:
while( (x--) > 0 )
