Pattern programs in C language

Pattern programs in C language: 
These programs print patterns of numbers and stars. These codes illustrate how to create patterns using C programming.
 The C programs involve usage of nested for loops (a for loop inside a for loop).
 A pattern of numbers, star or characters is a way of arranging these in some logical manner or they may form a sequence.
 Some of these patterns are triangles which have special importance in mathematics.
 Some patterns are symmetrical while others are not.
 Please see the complete page and look at comments for many different patterns.

Code :-

#include<stdio.h> #include<conio.h> void main() { int i,j; clrscr(); for(i=1;i<=6;i++) { for(j=1;j<=i;j++) { printf("*");//put any character } printf("\n"); } getch(); }
