C++ Exercises: Display the pattern like a pyramid using asterisk and each row contain an odd number of asterisks
Write a C++ program that displays the pattern like a pyramid using asterisks, with odd numbers in each row.
Sample Solution:
C++ Code :
#include <iostream> // Include the input/output stream library
using namespace std; // Using standard namespace
int main() // Main function where the execution of the program starts
{
int i, j, n; // Declare integer variables i, j, and n
// Display message asking for input
cout << "\n\n Display such a pattern like a pyramid containing odd number of asterisk in each row:\n";
cout << "-----------------------------------------------------------------------------------------\n";
cout << " Input number of rows: ";
cin >> n; // Read input for the number of rows from the user
// Loop to print the pyramid pattern containing odd numbers of asterisks in each row
for (i = 0; i < n; i++) // Loop for the number of rows
{
for (j = 1; j <= n - i; j++) // Loop to print spaces before the asterisks
{
cout << " "; // Print a space
}
for (j = 1; j <= 2 * i - 1; j++) // Loop to print asterisks in each row
{
cout << "*"; // Print an asterisk
}
cout << endl; // Move to the next line after each row is printed
}
}
Sample Output:
Display such a pattern like a pyramid containing odd number of asterisk in each row: ----------------------------------------------------------------------------------------- Input number of rows: 5 * *** ***** *******
