## Program to Print Mirrored Reverse Right Triangle Star Pattern in C, C++, and Python

Below are the ways to print Reverse Mirrored Right Triangle Star Pattern in C, C++, and Python.

### Method #1: Using For loop (Star Character)

Approach:

• Give the number of rows of the right triangle pattern as static input and store it in a variable.
• Iterate from 1 to given rows using the First For loop.
• Iterate from 1 to given rows using another for loop(Nested For loop)
• Check if the iterator value of the inner for loop is less than the given first iterator value using the If statement.
• If the statement is true then print space.
• Else print the star character with space.
• Print the newline character after the exit of the inner for loop.
• The Exit of the Program.

1) Python Implementation:

Below is the implementation:

# Give the number of rows of the right triangle pattern as static input and store it in a variable.
triNumRows = 8
# Iterate from 1 to given rows using First for loop.
for m in range(1, triNumRows+1):
# Iterate from 1 to given rows using another for loop(Nested For loop)
for n in range(1, triNumRows+1):
# Check if the iterator value of the inner for loop is less than the given first iterator value using the If statement.
if(n < m):
# If the statement is true then print space.
print(' ', end=' ')
else:
# Else print star character with space.
print('*', end=' ')
print()


Output:

 * * * * * * * *
* * * * * * *
* * * * * *
* * * * *
* * * *
* * *
* *
*

2) C++ Implementation

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{

// Give the number of rows of the right triangle pattern
//  as static input and store it in a variable.
int triNumRows = 8;
// Iterate from 1 to given rows using First for loop.
for (int m = 1; m <= triNumRows; m++) {
// Iterate from 1 to given rows using another for
// loop(Nested For loop)
for (int n = 1; n <= triNumRows; n++) {
/* Check if the iterator value of the inner for
* loop is less than the given first iterator
* value using the If statement.*/
if (n < m) {
// If the statement is true then print
// space.
cout << "  ";
}
else {
// Else print star character with space.
cout << "* ";
}
}
// Print the newline character after the exit of the
// inner for loop.
cout << endl;
}

return 0;
}

Output:

 * * * * * * * *
* * * * * * *
* * * * * *
* * * * *
* * * *
* * *
* *
*

3) C Implementation

Below is the implementation:

#include <stdio.h>

int main()
{

// Give the number of rows of the right triangle pattern
//  as static input and store it in a variable.
int triNumRows = 8;
// Iterate from 1 to given rows using First for loop.
for (int m = 1; m <= triNumRows; m++) {
// Iterate from 1 to given rows using another for
// loop(Nested For loop)
for (int n = 1; n <= triNumRows; n++) {
/* Check if the iterator value of the inner for
* loop is less than the given first iterator
* value using the If statement.*/
if (n < m) {
// If the statement is true then print
// space.
printf("  ");
}
else {
// Else print star character with space.
printf("* ");
}
}
// Print the newline character after the exit of the
// inner for loop.
printf("\n");
}
return 0;
}

Output:

 * * * * * * * *
* * * * * * *
* * * * * *
* * * * *

### Method #2: Using For Loop(User Character)

Approach:

• Give the number of rows of the right triangle pattern as user input and store it in a variable.
• Give the character to print as user input and store it in a variable.
• Iterate from 1 to given rows using the First For loop.
• Iterate from 1 to given rows using another for loop(Nested For loop)
• Check if the iterator value of the inner for loop is less than the given first iterator value using the If statement.
• If the statement is true then print space.
• Else print the star character with space.
• Print the newline character after the exit of the inner for loop.
• The Exit of the Program.

1) Python Implementation:

• Give the number of rows of the Right Triangle as user input using int(input()) and store it in a variable.
• Give the Character as user input using input() and store it in another variable.

Below is the implementation:

# Give the number of rows of the Right Triangle as user input using int(input()) and store it in a variable.
triNumRows = int(input(
'Enter some random number of rows of the Right Triangle Pattern = '))
# Give the Character as user input using input() and store it in another variable.
givencharacter = input('Enter some random character = ')
# Iterate from 1 to given rows using First for loop.
for m in range(1, triNumRows+1):
# Iterate from 1 to given rows using another for loop(Nested For loop)
for n in range(1, triNumRows+1):
# Check if the iterator value of the inner for loop is less than the given first iterator value using the If statement.
if(n < m):
# If the statement is true then print space.
print(' ', end=' ')
else:
# Else print star character with space.
print(givencharacter, end=' ')
print()


Output:

Enter some random number of rows of the Right Triangle Pattern = 9
Enter some random character = &
& & & & & & & & &
Â  Â  & & & & & & & &
Â  Â  Â  Â  & & & & & & &

Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  Â  &

2) C++ Implementation

• Give the number of rows of the Right Triangle as user input using cin and store it in a variable.
• Give the Character as user input using cin and store it in another variable.

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{

// Give the number of rows of the Right
// Triangle as user input using cin and store it in a
// variable.
int triNumRows;
char givencharacter;
cout << "Enter some random number of rows of the "
"Right Triangle Pattern = "
<< endl;
cin >> triNumRows;
// Give the Character as user input using cin and store
// it in another variable.
cout << "Enter some random character = " << endl;
cin >> givencharacter;
cout << endl;
// Iterate from 1 to given rows using First for loop.
for (int m = 1; m <= triNumRows; m++) {
// Iterate from 1 to given rows using another for
// loop(Nested For loop)
for (int n = 1; n <= triNumRows; n++) {
/* Check if the iterator value of the inner for
* loop is less than the given first iterator
* value using the If statement.*/
if (n < m) {
// If the statement is true then print
// space.
cout << "  ";
}
else {
// Else print given character with space.
cout << givencharacter << " ";
}
}
// Print the newline character after the exit of the
