PES Institute of Technology Bangalore South Campus DEPARTMENT OF INFORMATION SCIENCE ENGINEERING VI SEMESTER SOFTWARE TESTING LABORATORY MANUAL SUBJECT CODE: 10ISL68 Mr. ANIMESH GIRI SOFTWARE TESTING 1: Decision table approach for solving triangle problem Design and develop a program in a language of your choice to solve the triangle problem defined as follows : Accept three integers which are supposed to be the three sides of triangle and determine if the three values represent an equilateral triangle, isosceles triangle, scalene triangle, or they do not form a triangle at all. Derive test cases for your program based on approach, execute the test cases and discuss the results int main() int char 3 integers which are sides of to check is it a triangle or not if( ) else istriangle if if else if else else a return PESIT Bangalore South Campus LAB MANUAL BE.
