Program for triangular patterns of alphabets

Pattern printing has always been an interesting topic in programming languages. It emphasize on the usage of inner and outer loops in nested loops and create beautiful patterns from it.
Below are given some pattern using alphabets. Our task is to write programs for the below given patterns, such that each pattern should print on the basis of given input ‘n’, when n = count of alphabets.

First Pattern :

C
