Take a close look about the pattern and identify some noticeable things about it. Here are some.

The pattern consists of N * 2 - 1 rows.
When you look to the center horizontal plus line i.e. +++++++++ this line. It also consists of N * 2 - 1 columns.
For every other row, single plus symbol is printed after N - 1 blank spaces.

Based on the above observation let us write a C program to print plus star pattern.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
