pyramid

Conditions and loops12

Objective

Write a program that draws a centered pyramid of # characters whose height is given as the single argument.

Steps

Read the height from argv[1] and parse it with atoi.
Print one row per line. Row i, counting from 1, has n - i leading spaces followed by 2 * i - 1 # characters, then a newline.
If the height is zero or negative, print nothing.
If the program does not receive exactly one argument, print wrong number of arguments followed by a newline.

examples

$ ./pyramid 3 | cat -e

#$ ###$ #####$

$ ./pyramid 1 | cat -e

$ ./pyramid | cat -e
