Program to Print the Hollow Mirrored Rhombus Star Pattern in C, C++, and Python
Below are the ways to print the Hollow mirrored Rhonbus star Patterns in C, C++, and Python.
Method #1: Using For loop (Star Character)
Approach:
- Give the number of rows of the Hollow rhombus as static input and store it in a variable.
- Loop till the number of rows of the rhombus using For loop.
- Iterate till the first iterator using another For loop(Nested For loop).
- Print the space character in the inner for loop.
- Loop till the number of rows of the rhombus using For loop(Second Nested For loop).
- If the parent For loop iterator value is equal to 0 or the number of rows-1, then print star with a space character.
- If the current iterator’s value is equal to 0 or the number of rows-1, the print star with a space character.
- Check the above two statements true or false using the If condition statement.
- If it is true then print star with a space character.
- Else print space.
- Print the newline character after the end of two nested for loops.
- The Exit of the Program.
1) Python Implementation
Below is the implementation:
# Give the number of rows of the rhombus as static input and store it in a variable.
rhombusrows = 8
# Loop till the number of rows of the rhombus using For loop.
for m in range(rhombusrows):
# Iterate till the first iterator using another For loop(Nested For loop).
for n in range(m):
# Print the space character in the inner for loop.
print(' ', end='')
# Loop till the number of rows of the rhombus using For loop(Second Nested For loop).
for o in range(rhombusrows):
# If the parent For loop iterator value is equal to 0 or the number of rows-1, then print star with a space character.
# If the current iterator's value is equal to 0 or the number of rows-1, the print star with a space character.
# Check the above two statements true or false using the If condition statement.
# If it is true then print star with a space character.
# Else print space.
if(m == 0 or m == rhombusrows - 1 or o == 0 or o == rhombusrows - 1):
print('*', end=' ')
else:
print(' ', end=' ')
# Print the newline character after the end of two nested for loops.
