6. Note: Questions (1), (2) and (3) are based on the following code;a=1; b=2; c=3; d=4;
if (a = = 1)
{ print “You entered 1”; }
else
{ print “N/A”; }
x = a + b;
if(x == 3)
{ print ”You entered 3!”; }
else if (d==4)
{ print “Congratulations !! You are the winner !”; }
else { print “N/A”; }
How many test cases, at minimum, are required for statement coverage?
