## Program to Print an Inverted Right Triangle of Numbers in C, C++, and Python

Below are the ways to Print an Inverted Right Triangle of Numbers in C, C++, and Python.

### Method #1: Using For Loop (Static Input)

Approach:

• Give the number of rows of the Inverted Right Triangle as static input and store it in a variable.
• Loop from the given number of rows to 0 using For loop and take iterator value as m.
• Loop till the iterator value of the first loop using another nested For loop.
• Print the First Loop iterator value that is m and space character.
• Print the newline character after inner for loop.
• The Exit of the Program.

1) Python Implementation

Below is the implementation:

# Give the number of rows of the Inverted Right Triangle as static input and store it in a variable.
triNumRows = 13
# Loop from the given number of rows to 0 using For loop and take iterator value as m.
for m in range(triNumRows, -1, -1):
# Loop till the iterator value of the first loop using another nested For loop.
for n in range(m):
# Print the First Loop iterator value that is m and space character.
print(m, end=' ')
# Print the newline character after inner for loop.
print()


Output:

13 13 13 13 13 13 13 13 13 13 13 13 13
12 12 12 12 12 12 12 12 12 12 12 12
11 11 11 11 11 11 11 11 11 11 11
10 10 10 10 10 10 10 10 10 10
9 9 9 9 9 9 9 9 9
8 8 8 8 8 8 8 8
7 7 7 7 7 7 7
6 6 6 6 6 6
5 5 5 5 5

2) C++ Implementation

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{

// Give the number of rows of the Inverted Right
// Triangle as static input and store it in a variable.
int triNumRows = 8;
// Loop from the given number of rows to 0 using For
// loop and take iterator value as m.
for (int m = triNumRows; m >= 0; m--) {

// Loop till the iterator value of the first loop
// using another nested For loop.
for (int n = 0; n < m; n++) {
// Print the First Loop iterator value that is m
// and space character.
cout << m << " ";
}
// Print the newline character after inner for loop.
cout << endl;
}

return 0;
}

Output:

8 8 8 8 8 8 8 8
7 7 7 7 7 7 7
6 6 6 6 6 6
5 5 5 5 5
4 4 4 4

3) C Implementation

Below is the implementation:

#include <stdio.h>

int main()
{

// Give the number of rows of the Inverted Right
// Triangle as static input and store it in a variable.
int triNumRows = 8;
// Loop from the given number of rows to 0 using For
// loop and take iterator value as m.
for (int m = triNumRows; m >= 0; m--) {

// Loop till the iterator value of the first loop
// using another nested For loop.
for (int n = 0; n < m; n++) {
// Print the First Loop iterator value that is m
// and space character.
printf("%d ", m);
}
// Print the newline character after inner for loop.
printf("\n");
}
return 0;
}

Output:

8 8 8 8 8 8 8 8
7 7 7 7 7 7 7

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

Approach:

• Give the number of rows of the Inverted Right Triangle as user input and store it in a variable.
• Loop from the given number of rows to 0 using For loop and take iterator value as m.
• Loop till the iterator value of the first loop using another nested For loop.
• Print the First Loop iterator value that is m and space character.
• Print the newline character after inner for loop.
• The Exit of the Program.

1) Python Implementation

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

Below is the implementation:

# Give the number of rows of the Inverted 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 Inverted Right Triangle Pattern = '))
# Loop from the given number of rows to 0 using For loop and take iterator value as m.
for m in range(triNumRows, -1, -1):
# Loop till the iterator value of the first loop using another nested For loop.
for n in range(m):
# Print the First Loop iterator value that is m and space character.
print(m, end=' ')
# Print the newline character after inner for loop.
print()


Output:

Enter some random number of rows of the Inverted Right Triangle Pattern = 7
7 7 7 7 7 7 7
6 6 6 6 6 6
5 5 5 5 5

2) C++ Implementation

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

Below is the implementation:

#include <iostream>
using namespace std;

int main()
{

// Give the number of rows of the Inverted Right
// Triangle as user input using cin and store it in a
// variable.
int triNumRows;
cout << "Enter some random number of rows of the "
"Inverted Right Triangle Pattern = "
<< endl;
cin >> triNumRows;
// Loop from the given number of rows to 0 using For
// loop and take iterator value as m.
for (int m = triNumRows; m >= 0; m--) {

// Loop till the iterator value of the first loop
// using another nested For loop.
for (int n = 0; n < m; n++) {
// Print the First Loop iterator value that is m
// and space character.
cout << m << " ";
}
// Print the newline character after inner for loop.
cout << endl;
}

return 0;

Give the number of rows of the Inverted Right Triangle as user input using scanf and store it in a variable.

Below is the implementation:

#include <stdio.h>

int main()
{

// Give the number of rows of the Inverted Right
// Triangle as user input using scanf and store it in a
// variable.
int triNumRows;
scanf("%d", &triNumRows);
// Loop from the given number of rows to 0 using For
// loop and take iterator value as m.
for (int m = triNumRows; m >= 0; m--) {

// Loop till the iterator value of the first loop
// using another nested For loop.
for (int n = 0; n < m; n++) {
// Print the First Loop iterator value that is m
// and space character.
printf("%d ", m);
}
// Print the newline character after inner for loop.
printf("\n");
}
return 0;
}
