Write a C++ program to print sandglass alphabets pattern using for loop.
#include<iostream>
using namespace std;
int main()
{
int rows, i, j, k, alphabet;
cout << "Enter Sandglass Pattern of Alphabets Rows = ";
cin >> rows;
cout << "Printing Sandglass Alphabets Pattern\n";
alphabet = 64;
for (i = 1; i <= rows; i++)
{
for (j = 1; j < i; j++)
{
cout << " ";
}
for (k = i; k <= rows; k++)
{
cout << char(alphabet + k) << " ";
}
cout << "\n";
}
for (i = rows - 1; i >= 1; i--)
{
for (j = 1; j < i; j++)
{
cout << " ";
}
for (k = i; k <= rows; k++)
{
cout << char(alphabet + k) << " ";
}
cout << "\n";
}
}
C++ program to print the sandglass alphabets pattern using a while loop.
#include<iostream>
using namespace std;
int main()
{
int rows, i, j, k, alphabet;
cout << "Enter Sandglass Pattern of Alphabets Rows = ";
cin >> rows;
cout << "Printing Sandglass Alphabets Pattern\n";
alphabet = 64;
i = 1;
while (i <= rows)
{
j = 1;
while (j < i)
{
cout << " ";
j++;
}
k = i;
while (k <= rows)
{
cout << char(alphabet + k) << " ";
k++;
}
cout << "\n";
i++;
}
i = rows - 1;
while (i >= 1)
{
j = 1;
