//WHİLE
/*4.16 (Triangle-Printing Program) Write a program that prints the following patterns separately,
one below the other. Use for loops to generate the patterns. All asterisks ( * ) should be printed by a single printf statement of the form printf("%s", "*" ) ; (this causes the asterisks to print side by
side). [Hint: The last two patterns require that each line begin with an appropriate number of
blanks.]*/
