Question

for C++

10.) (8) Indicate which of the following assignment statements are legal if x is an int variable and y is a float variable. Show what is stored in the receiving variables if the statement is correct: а, у х: c. y (float) x; d. x (int) y r++ A homeowner would like to calculate the idla of a rectangle

Answer 1

Answer is as follows :

All the given statements are legal in C++.

Let x = 10 i.e. int

and y = 20.2 i.e. float

The output stored in the recieving variables is as follows :

a) y = x

Here the variable x has int value i.e. 10 passes to variable y i.e. 10.

So y stores only 10.

b) x = y

int this only int part of float variable y i.e. 20 only from 20.2 is transferred to ariable x.

So x stores the 20 only.

c) y = (float) x

here the variable x is converted to float and store the result to float variable y.

now the x contain 10 but in float it is equal to 10.0.

So the y contains 10.0 or we can say only 10.(both are same).

d) x= (int) y

here float variable is converted to int but part without decimal is conerted.

So now float variable y has 20.2 and after conversion it gets only 20 as integer i.e. store in variable x.

So the x stores 20 only.

if there is any query please ask in comments...
