Explanation / Answer

for (int i = 1; i <= n; i++) {
// iteration
}

there will be n iteration because the conditon define in loop is <=n so it will run n times giving you n iterations.

Answer37:(A)

4.0 becuse it the function of maths we are calling will round of the value provided to it.
--------------------------------------------------------

Answer38:(A)
test.date satisfy the condtion given it will run the code without any run time error or syntax error
--------------------------------------------------------

Answer39:(C)
because after evaluting the condition first case of the codtion will be truwe and it will pass on we are using or operator (||) here so the value of X will not be changed.
------------------------------------------------------------

Answer40:(D)
it will print the text message 10times because we use ++ condtion so it will lead it to print 10times.
