1. Show that McCabe's cyclamate number is an interval scale measure.
2. Calculate McCabe's cyclamate number on the following source code. Draw a control ?ow graph. Label the regions with Roman numerals.
read x,y,z;
type = ‘‘scalene'';
if (x == y or x == z or y == z) type =‘‘isosceles''; if (x == y and x == z) type =‘‘equilateral'';
if (x >= y+z or y >= x+z or z >= x+y) type =‘‘not a triangle''; if (x 0 or y 0 or| z 0) type =‘‘bad inputs''; print type;
