Mario
Problem to Solve
Toward the beginning of World 1-1 in Nintendo’s Super Mario Brothers, Mario must hop over adjacent pyramids of blocks, per the below.
In a file called mario.c
in a folder called mario-more
, implement a program in C that recreates that pyramid, using hashes (#
) for bricks, as in the below:
# #
## ##
### ###
#### ####
And let’s allow the user to decide just how tall the pyramids should be by first prompting them for a positive int
between, say, 1 and 8, inclusive.
Examples
Here’s how the program might work if the user inputs 8
when prompted:
$ ./mario
Height: 8
# #
## ##
### ###
#### ####
##### #####
###### ######
####### #######
######## ########
Here’s how the program might work if the user inputs 4
when prompted:
$ ./mario
Height: 4
# #
## ##
### ###
#### ####
Here’s how the program might work if the user inputs 2
when prompted:
$ ./mario
Height: 2
# #
## ##
And here’s how the program might work if the user inputs 1
when prompted:
$ ./mario
Height: 1
# #
If the user doesn’t, in fact, input a positive integer between 1 and 8, inclusive, when prompted, the program should re-prompt the user until they cooperate:
$ ./mario
Height: -1
Height: 0
Height: 42
Height: 50
Height: 4
# #
## ##
### ###
#### ####
Notice that width of the “gap” between adjacent pyramids is equal to the width of two hashes, irrespective of the pyramids’ heights.
