Pyramid Patterns in C
FREE
Overview
In this article, we are going to discuss the pyramid pattern in C. The Pyramid pattern in C consists of the pyramid pattern of numbers, pyramid pattern of stars, and pyramid pattern of alphabets. Pyramid designs are all made up of polygons. Each pattern program contains two or more loops.
Pattern program can also contain if-else statements.
The complexity of the pattern or logic determines the number of loops. The first for loop represents the row, whereas the second loop represents the column. Solving pattern printing problems is the simplest approach to understanding how a nested loop works.
In C, there are three types of pyramid patterns:
- Star Pyramid Patterns
- Number Pyramid Patterns
- Alphabets Pyramid Patterns
Star Pyramid Patterns
The Star pyramid contains half pyramids, inverted half pyramids, inverted right half pyramids, right half pyramids, full pyramids in 180 degrees, full pyramids in the opposite direction, full pyramid, zig-zag pattern, rectangle pattern, rhombus pattern, butterfly pattern, diamond-shaped pyramids.

Explanation: Let's understand it by the below figure.
If we take the indices of every star
And we add add all corresponding indices. then we get a number which is divisble by 4 and we will print stars here. and when our row number is equal to 2 and column number is divisble by 4 then we will print star. so, the condition will be followed here (((i + j) % 4 == 0) || (i == 2) && j % 4 == 0) and we will print spaces in remaining space.

Conclusion
- Pattern programs are simply patterns made up of numbers, alphabets, or symbols in a specific order.
- Pyramid pattern in C have the advantage of learning how to use loops and if-else statements.
- These types of pattern programs are simple to solve utilizing the for loop condition.
- Beginners can use pattern programs to visualize how each iteration of a loop works.
- By practicing pyramid pattern we can build our logical thinking of problem solving.
