Question

Q3. For the given program, draw the Control Flow Graph and find its cyclomatic complexity and write all linear independent paths and derive atleast one test case for each path.(5+2+2+1)
1- #include
2- void main()
3- {
4- int a,b,c,flag;
5-printf("enter three sides of a triangle");
6-scanf("%d%d%d",&a,&b,&c);
7- printf(“Side A is : %d”, a);
8- printf(“Side B is : %d”, b);
9- printf(“Side C is : %d”, c);
10-if((a<b+c) && (b<a+c) && (c< a+b))
11- flag=1;
12- else
13- flag=0;
14-if(flag)
15-
16-if((a==b) && (b==c))
17-printf(“equilateral triangle”);
18-else
19-if ((a! =b) && (a!=c) && (b!=c))
20-printf(“scalene”);
21-else
22-printf(“isosceles”);
23-}
24-else
25-printf (“not triangle”);
26-printf (“end of program”);​
