if ( $$A$$ [ $$i$$ ] $$==oldc$$ [ $$j$$ ] $$A$$ [ $$i$$ ]
$$=newc$$ [ $$j$$ ]; $$\left. \, \right\}$$
The procedure is tested with the following four test cases;
$$\eqalign{
& \left( 1 \right)\,\,\,oldc = ''abc'',\,\,newc\, = \,''dab'' \cr
& \left( 2 \right)\,\,\,oldc\, = \,''cdc'',\,\,newc\, = \,''bed'' \cr
& \left( 3 \right)\,\,\,oldc\, = \,''bca'',\,newc\, = \,''cda'' \cr
& \left( 4 \right)\,\,\,oldc\, = \,''abc'',\,newc\, = \,''bac'' \cr} $$
If array $$A$$ is made to hold the string $$''abcde'',$$ which of the above four test cases will be successful is exposing the flaw in this procedure?
$$i)$$ When coefficient $$a$$ is zero or irrespective of discriminate
$$ii)$$ When discriminate is positive.
$$iii)$$ When discriminate is zero
$$iv)$$ When discriminate is negative
Only in cases $$(ii)$$ & $$(iii)$$ the stored roots are valid Otherwise $$0$$ is stored in the roots the function returns $$0$$ when the roots are valid & - $$1$$ otherwise. The function also ensures root $$1$$ $$> =$$ root $$2.$$

A software test engineer is assigned the job of doing block box testing. He comes up with the following test cases, many of which are redundant

Which one of the following options provide the set of non-redundant tests using equivalence class partitioning approach from input perspective for black box testing?
begin
if $$\left( {a = \,\, = b} \right)\,\,\left\{ {S1;\,\,exit;} \right\}$$
else if $$\left( {c = \,\, = d} \right)\,\,\left\{ {S2;} \right\}$$
else $$\left\{ {S3;\,\,exit;} \right\}$$
$$S4;$$
end
The test cases $${T_1},\,{T_2},\,{T_3}\,\,\& \,{T_4}$$ given below are expressed in terms of the properties satisfied by the values of variables $$a, b, c$$ and $$d.$$ The exact values are not given.
$${T_1}:\,a,\,b,\,c\,\& \,d$$ are all equal
$${T_2}:\,a,\,b,\,c\,\& \,d$$ are all distinct
$${T_3}:\,a = b\,\,\,\& \,\,\,\,c\,!\, = \,d$$
$${T_4}:\,a! = b\,\,\,\& \,\,\,\,c\, = \,d$$
Which of the test suites given below ensures coverage of statements $${S_1},\,{S_2},\,{S_3}\,\,\& \,{S_4}$$ ?
$${\rm I}.\,\,\,\,\,\,$$ The cyclomatic complexity of a module is equal to the maximum number of
$$\,\,\,\,\,\,\,\,\,\,\,$$linearly independent circuits in the graph.
$${\rm II}.\,\,\,$$ The cyclomatic complexity of a module is the number of decisions in the
$$\,\,\,\,\,\,\,\,\,\,$$module plus one, where a decision is effectively any conditional statement in
$$\,\,\,\,\,\,\,\,\,\,$$the module.
$${\rm III}\,$$ The cyclomatic complexity can also be used as a number of linearly
$$\,\,\,\,\,\,\,\,\,\,$$independent paths that should be tested during path coverage testing.
