What is a star in programming ?
In any programming language, star patterns are a common pattern widely used because it helps to improve logical thinking and flow control knowledge. You must use two or three loops to create a star pattern in the C language. The number of loops depends on the pattern that you need to create. For pattern, a minimum of two is used i.e. one for a row and one for a column. The First loop is called an outer loop that shows the rows, and the second loop is called an inner loop that shows columns.
Star patterns are a series of * or any other character used to create some pattern or any geometrical shape such as – square, triangle(Pyramid), rhombus, heart etc. These patterns are often prescribed by many programming books and are best for practicing flow control statement.
