C Program To Print Character Pyramid Pattern

Pyramid patterns is a classic logical programming exercise where a triangular looking pattern is printed by treating the output screen as a matrix and printing a given character. In this article, we will explore how to print various alphabet pyramid patterns using C program.

Half Pyramid Pattern

Half Pyramid Pattern is a triangular pattern where each row starts with 'A' and increases by one character per row. Characters are aligned to the left resembling a right-angled triangle with the hypotenuse facing right.
