Lab2 3.39 (Checkerboard Pattern of Asterisks) Write a program that displays the following checker- board pattern: Your program must use only three output statements, one of each of the following forms printf("s","): printf("%s",""); puts( ); // outputs a newline 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 (6) should be printed by a single printf statement of the form printf("%s". "*"): (this causes the asterisk to print side by side). (Hint: The last two patterns require that each line begin with an appropriate number of blanks.) (A) (B) (C) (D) ********.. were RRRR code example for (A) is given, and now you are required to program 2 questions from the three of ((B), (C),(D)). Double loop may be required
