Program to Print Hollow Inverted Right Triangle Star Pattern in C, C++, and Python

Below are the ways to print a Hollow Inverted Right Triangle Star Pattern in C, C++, and Python.

• Using For Loop(Star Character)
• Using For Loop(User Character)

Method #1: Using For Loop(Star Character)

Approach:

• Give the number of rows of the Hollow 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 from the iterator value of the first loop to 0 using another nested For loop.
• If m equals zero, rows, n, or n equals one value, the if statement prints stars.
• Else print 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 Hollow Inverted Right Triangle as static input and store it in a variable.
triNumRows = 7
# Loop from the given number of rows to 0 using For loop and take iterator value as m.
for m in range(triNumRows, 0, -1):
    # Loop from the  iterator value of the first loop to 0 using another nested For loop.
    for n in range(m, 0, -1):
        # If m equals zero, rows, n, or n equals one value, the if statement prints stars.
        if m == 1 or m == triNumRows or n == 1 or n == m:
            print('*', end='')
        else:
            print(' ', end='')
    # Print the newline character after inner for loop.
    print()

Output:

    int triNumRows = 7;
    // 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--) {

3) C Implementation

• Give the number of rows of the right-angled triangle as user input using scanf and store it in a variable.
• Give the Character as user input using scanf and store it in another variable.

Below is the implementation:

#include <stdio.h>

int main()
{

    int trianglerows;
    char givencharacter;
    // Give the number of rows of the right-angled triangle
    // as user input using cin and store it in a variable.
    scanf("%d", &trianglerows);

    // Give the Character as user input using cin and store
    // it in another variable.
    scanf("%c", &givencharacter);
    printf("\n");
    // Loop from 1 to the number of rows using For loop.
    for (int m = 1; m <= trianglerows;
         m++) { // Loop from 1 to first loop iterator value
                // using another Nested For loop.
        for (int n = 1; n <= m; n++) {
            // Print the star character with space in the
            // inner For loop.
            printf("%c ", givencharacter);
        }
        // Print the newline character after ending of inner
        // For loop.
        printf("\n");

3) C Implementation

• Give the number of rows of the right-angled triangle as user input using scanf and store it in a variable.
• Give the Character as user input using scanf and store it in another variable.

Below is the implementation:

#include <stdio.h>

int main()
{

    int trianglerows;
    char givencharacter;
    // Give the number of rows of the right-angled triangle
    // as user input using cin and store it in a variable.
    scanf("%d", &trianglerows);

    // Give the Character as user input using cin and store
    // it in another variable.
    scanf("%c", &givencharacter);
    printf("\n");
    // Loop from 1 to the number of rows using For loop.
    for (int m = 1; m <= trianglerows;
         m++) { // Loop from 1 to first loop iterator value
                // using another Nested For loop.
        for (int n = 1; n <= m; n++) {
            // If you closely examine the pattern, you will
            // notice that the
            // star is available on the first or last column
            // or row.
            // So, for the first or last column or row,
            // print a star, otherwise, print space.
            if (m == 1 || m == trianglerows || n == 1
                || n == m)
                printf("%c ", givencharacter);
            else
                printf("  ");
        }
        // Print the newline character after ending of inner
        // For loop.
        printf("\n");
    }
    return 0;
}

Program to Print Plus Star Pattern in C, C++, and Python

Below are the ways to Print Plus Star Pattern in C, C++, and Python.

• Using For Loop (Star Character)
• Using For Loop (User Character)

Method #1: Using For Loop (Star Character)

Approach:

• Give the number of rows as static input and store it in a variable.
• Loop from 1 to 2*number of rows using For loop.
• Loop from 1 to 2*number of rows using another For loop(Nested For loop).
• Check if the parent loop iterator value is equal to the number of rows using the If statement.
• Check if the inner loop iterator value is equal to the number of rows using the If statement.
• Merge these both statements using or operator.
• If this statement is true then print star character.
• Else print space character.
• Print the newline Character after the end of the inner for loop.
• The Exit of the Program.

1) Python Implementation

Below is the implementation:

# Give the number of rows as static input and store it in a variable.
numberows = 9
# Loop from 1 to 2*number of rows using For loop.
for m in range(1, 2*numberows):
    # Loop from 1 to 2*number of rows using another For loop(Nested For loop).
    for n in range(1, 2*numberows):
        '''Check if the parent loop iterator value is equal to the number of rows using the If statement.
        Check if the inner loop iterator value is equal to the number of rows using the If statement.
        Merge these both statements using or operator.'''
        if(m == numberows or n == numberows):
            # If this statement is true then print star character.
            print('*', end=' ')
        else:
            # Else print space character.
            print(' ', end=' ')

    # Print the newline character after the end of the inner For loop.
    print()

Method #2: Using For Loop (User Character)

Approach:

• Give the number of rows as user input and store it in a variable.
• Give the character as user input and store it in a variable.
• Loop from 1 to 2*number of rows using For loop.
• Loop from 1 to 2*number of rows using another For loop(Nested For loop).
• Check if the parent loop iterator value is equal to the number of rows using the If statement.
• Check if the inner loop iterator value is equal to the number of rows using the If statement.
• Merge these both statements using or operator.
• If this statement is true then print the given character.
• Else print space character.
• Print the newline Character after the end of the inner for loop.
• The Exit of the Program.

1) Python Implementation

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

Below is the implementation:

# Give the word as user input using int(input()) and store it in a variable.
numberows = int(input('Enter some random number of rows = '))
# Give the Character as user input using input() and store it in another variable.
givencharacter = input('Enter some random character = ')
# Loop from 1 to 2*number of rows using For loop.
for m in range(1, 2*numberows):
    # Loop from 1 to 2*number of rows using another For loop(Nested For loop).
    for n in range(1, 2*numberows):
        '''Check if the parent loop iterator value is equal to the number of rows using the If statement.
        Check if the inner loop iterator value is equal to the number of rows using the If statement.
        Merge these both statements using or operator.'''

        else:
            # Else print space character.
            print(' ', end=' ')

    # Print the newline character after the end of the inner For loop.
    print()
