Suppose we are to produce, on the screen, an upside-down right-angle triangle so that the upper-left corner has the right angle, where the triangle is printed with '+'. The dimension of the triangle is specified in an int variable dim. The variable specifies the number of '+' that appears in the first line. Then the number of '+' decreases each time the output goes to the next line. The number of '+' in the last line of the output is 1. For example, the program may run like: Specify dimension: 9 +++++++ ++ A straightforward way to write the program is to use a double for-loop with the external loop iterating over the line positions and the internal loop the positions within a line. Below is the central part of the program, where row and col are the two iteration variables. Fill the blanks. Scanner keyboard; int dim, row, col; keyboard new Scanner( System.in); System.out.print( "Specify dimension: dim = for ( } for ( } System.out.print( "+" System.out.println(); " ); // receive input, 2 points. { // external loop, 4 points ) { // internal loop, 4 points Suppose we are to produce, on the screen, an upside-down right-angle triangle so that the upper-left corner has the right angle, where the triangle is printed with '+'.
