Algorithm to print triangle pattern of palindrome strings
This program is silimar to right triangle star pattern program.
  • Take the number of rows(N) of right triangle as input from user using scanf function.
  • Number of characters in Kth row is always 2K+1. 0th row contains 1 character, 1st row contains 3 characters, 2nd row contains 5 charcaters and so on.
  • In any row, we will first print the characters in increasing order of their ASCII value till mid of the row and then in decreasing order.
  • We will use two for loops to print right triangle of palindrome strings.
    • Outer for loop will iterate N time(from i = 0 to 2N-2 in increment of 2). Each iteration of outer loop will print one row of the pattern.
    • Each iteration of inner loop will print a palindrome string as explained above.

Here is the matrix representation of the above mentioned pattern. The row numbers are represented by i whereas column numbers are represented by j.

int main() {
    int i, j, rows, count=0;

    printf("Enter the number of rows\n");
    scanf("%d", &rows);

    for (i = 0; i < 2*rows; i=i+2) {
        for (j = 0; j <= i; j++) {
            printf("%c", 'A'+count);
            if(j < i/2)
        count = 0;
Enter the number of rows

Advantages of the Palindrome Triangle Pattern Program in C

As you delve into the world of programming, exploring the Palindrome Triangle Pattern Program in C offers several advantages that contribute to your learning and skill development. Let's explore why this program is advantageous for you:
  • Understanding Palindromes : This program provides a practical application for understanding palindromes. It demonstrates how palindromes, which are sequences that read the same forwards and backwards, can be used in a pattern. This helps you grasp the concept of palindromes more effectively.

  • Enhancement of Pattern Recognition Skills : Designing and implementing the Palindrome Triangle Pattern Program challenges you to recognize and understand palindrome patterns. It improves your ability to identify and analyze patterns in a sequence of characters, a skill that is valuable in programming.

  • Improvement of Algorithmic Thinking : The program encourages you to think algorithmically, devising a strategy to generate and display palindrome patterns. This improves your ability to break down a complex problem into logical steps, a crucial skill in programming.

  • Introduction to Nested Loops : Writing this program requires the use of nested loops to control the number of rows and columns printed in each iteration. Nested loops are a fundamental concept in programming, and this program introduces you to their use in a practical context.

  • Application of String Manipulation Concepts : Implementing this program enhances your understanding of string manipulation concepts, such as reversing a string to form a palindrome. It provides you with hands-on experience in applying these concepts, which are essential in many programming tasks.

  • Preparation for Advanced Programming Challenges : The skills and concepts you learn from this program serve as a foundation for tackling more advanced programming challenges. It prepares you for problems that require algorithmic thinking, pattern recognition, and efficient use of loops.
