C Program to Print Hourglass Pattern Last Updated : 13 Dec, 2024 Comments Improve Suggest changes Like Article Like Report The Hourglass Pattern is a symmetrical pattern similar to an hourglass shape. It can be visualized as an inverted full pyramid placed on a regular full pyramid. In this article, we will learn how to print the Hourglass Pattern using a C program. Program to Print Hourglass Pattern in C Star Pattern #include <stdio.h> int main() { int n = 5; // Outer loop to iterate through each row for (int i = 0; i < 2 * n - 1; i++) { // Determine the row level relative to the center int l = (i < n) ? i : 2 * n - 2 - i; // Print leading spaces for (int j = 0; j < l; j++) { printf(" "); } // Print stars in the current row for (int k = 0; k < 2 * (n - l) - 1; k++) { printf("*"); } printf("\n"); } return 0; } Number Pattern #include <stdio.h> int main() { int n = 5; // Outer loop to iterate through each row for (int i = 0; i < 2 * n - 1; i++) { // Determine the row level relative to the center int l = (i < n) ? i : 2 * n - 2 - i; // Print leading spaces for (int j = 0; j < l; j++) { printf(" "); } // Print numbers in the current row for (int k = 0; k < 2 * (n - l) - 1; k++) { printf("%d ", k + 1); } printf("\n"); } return 0; } Alphabet Pattern #include <stdio.h> int main() { int n = 5; // Outer loop to iterate through each row for (int i = 0; i < 2 * n - 1; i++) { // Determine the row level relative to the center int l = (i < n) ? i : 2 * n - 2 - i; // Print leading spaces for (int j = 0; j < l; j++) { printf(" "); } // Print alphabets in the current row for (int k = 0; k < 2 * (n - l) - 1; k++) { printf("%c ", k + 'A'); } printf("\n"); } return 0; } Output* * * * * * * * * | 1 2 3 4 5 6 7 8 9 | A B C D E F G H I * * * * * * * | 1 2 3 4 5 6 7 | A B C D E F G * * * * * | 1 2 3 4 5 | A B C D E * * * | 1 2 3 | A B C * | 1 | A * * * | 1 2 3 | A B C * * * * * | 1 2 3 4 5 | A B C D E * * * * * * * | 1 2 3 4 5 6 7 | A B C D E F G* * * * * * * * * | 1 2 3 4 5 6 7 8 9 | A B C D E F G H IExplanation:The outer loop runs for 2 * n - 1 iterations for printing each row of the pattern.For rows i < n, it processes the top half (inverted pyramid).For rows i >= n, it processes the bottom half (regular pyramid).The l variable determines the relative position of the current row from the top or bottom center:Top half: l = i.Bottom half: l = 2 * n - 2 - i.The first inner loop prints the number of leading spaces.The second inner loop prints the stars (or numbers/alphabet).
