Write C a program called triangles that accepts command line arguments for a height (h), a character (c), orientation (o) and justification (j). The program will print a triangle of height h using the c character with orientation (Up or Down) and justification (Left, Right or Center). The usage should be something like triangles h c o j.

Some examples:

Command: triangles 4 ? U L

Prints: Upward pointing, left-justified triangle of height 4 using the ? character, as follows:

? ?? ??? ????
