        }

        printf("\n");
    }

    return 0;
}
  

💻 Expected Output (Input: 5):

Enter the number:
5

📘 Explanation

This program prints an inverted star triangle pattern using nested loops. The outer loop starts from the entered number and decreases to 1, controlling the number of rows. The first inner loop prints leading spaces to align the pattern, while the second inner loop prints the required number of stars in each row. As the number of stars decreases with each iteration, an inverted star triangle is formed.

🧠 Algorithm

1. Read the number from the user.
2. Start the outer loop from the entered number down to 1.
3. Print leading spaces for proper alignment.
4. Print stars equal to the current row value.
5. Move to the next line after each row.
6. Repeat until the complete inverted star triangle is displayed.

⭐ C Program to Print Inverted Repeated Binary Triangle Pattern

📄 Source Code:

#include<stdio.h>

int main()
{
    int num;

    printf("Enter the number:\n");
    scanf("%d",&num);

    for(int i=num;i>=1;i--)

        }

        printf("\n");
    }

    return 0;
}
  

💻 Expected Output (Input: 5):

Enter the number:
5

 0 0 0 0
  1 1 1
   0 0
    1
  

📘 Explanation

This program prints an inverted repeated binary triangle pattern using nested loops. The outer loop starts from the entered number and decreases to 1, controlling the number of rows. The first inner loop prints leading spaces for proper alignment, while the second inner loop prints either 1 or 0 repeatedly based on the parity of the current row. The expression i % 2 returns 1 for odd rows and 0 for even rows, creating an inverted repeated binary pattern.

🧠 Algorithm

1. Read the number from the user.
2. Start the outer loop from the entered number down to 1.
3. Print leading spaces for proper alignment.
4. Print i % 2 repeatedly for each row.
5. Move to the next line after each row.
6. Repeat until the complete inverted repeated binary triangle is displayed.

📘 Explanation

This program prints an inverted binary triangle pattern using nested loops. The outer loop controls the number of rows, starting from the entered number and decreasing to 1. The first inner loop prints leading spaces for proper alignment, while the second inner loop prints alternating 1 and 0 values using the expression j % 2. Since the remainder alternates between 1 and 0 for consecutive values of j, the program creates a binary triangle in inverted form.

🧠 Algorithm

1. Read the number from the user.
2. Start the outer loop from the entered number down to 1.
3. Print leading spaces for proper alignment.
4. Print alternating 1 and 0 values using j % 2.
5. Move to the next line after each row.

📘 Explanation

This program prints an inverted repeated alphabet triangle pattern using nested loops. The outer loop starts from the entered number and decreases to 1, controlling the number of rows. The first inner loop prints leading spaces to align the pattern, while the second inner loop prints the same uppercase alphabet repeatedly in each row. The expression i + 64 converts the current row number into its corresponding uppercase ASCII character, producing a repeated alphabet triangle in inverted form.
