Number of testcases required for branch coverage will be 2.
In branch coverage we need to check whether all the
branches are exercised.
Here we have 3 branches all If statements we need to
consider.They are A<10,C>100,C<100
Line 1 - Read(A,C)
Line 2 - If(A<10) then
Line 3 - Print A;
Line 4 - Endif
Line 5 - If(C>100)then
Line 6 - Print C is greater then A
Line 7 - else if(C<100) then
Line 8 - print C
Line 9 - End if
So take the values as follows
Testcase 1 : A=5 and C=120
For this set of values Line1 - Line6 are executed
Now for the Line7 - Line9 to be executed take the value of
c as less than 100
So Testcase 2 : A=5(can be any value as Line 2,3,4 are
already exercised in testcase1)and c=80
For this set of values Line7-Line9 will be exercised
