It is an art of programming to print some sort of pattern on the screen. This can be a series of numbers, letters, or special characters to form a pattern. The simplest example of a pattern is the Fibonacci series (1, 1, 2, 3, 5, 8, 13, 21, 34 and so on). Then there are other patterns which are designs on screen, say a pyramid of stars. So, basically, pattern programming is simply printing a pattern on the screen.

Before jumping right onto the programs, let us understand the basic logic of coding patterns. Patterns are always programmed through nested loops– mostly nested for loops. This is because loops are syntactically easier to understand and concise.
The outer loop is always concerned with the number of lines. So, let’s say if you have to print a pattern spanning five lines, the outer loop will always run five times.
The inner loop is always concerned with the number of elements in each line. So, let’s say if you have to print 1 star in the first line, 2 stars in the second line and so on, the inner loop would control this logic.
Depending on the pattern, sometimes there are more than one inner loops or three levels of nested loops. Also, there is the involvement of spaces and tabs to produce the desired pattern.
