Question

What is the output of the following program segment?
main $\left(\right)$
$\{$
$floata,b,c,X,Y,Z;$
$a=9;b=12;c=3;$
$X=a-b/3+c\ast 2-1$
$Y=a-b/(3+c)\ast (2-1)$
$Z=a-\left(b/\right(3+c)\ast 2)-1$
$printf("X=\%f╲nY=\%f╲nZ=\%Y",X,Y,Z);$
$\}$

• A. $X=10.000000,Y=7.000000,Z=4.000000$
• B. $X=10.000000,Y=10.000000,Z=10.000000$
• C. $X=3.000000,Y=0.500000,Z=7.333334$
• D. None of these

Answer 1

The correct option is A $X=10.000000,Y=7.000000,Z=4.000000$

main()

{
float a,b,c,X,Y,Z;
a=9;b=12;c=3;
X=a−b/3+c∗2−1

Y=a−b/(3+c)∗(2−1)
Z=a−(b/(3+c)∗2)−1
printf("X=%f╲nY=%f╲nZ=%Y",X,Y,Z);

}

A float is a term is used in various programming languages to define a variable with a fractional value. Numbers created using a float variable declaration will have digits on both sides of a decimal point. This is in contrast to the integer data type, which houses an integer or whole number.

X=9-12/3+3*2-1=10

Y=9-12/ (3+3)*(2-1) =7

Z=9-(12/ (3+3)*2)-1=4

Output:-

X=10.000000 ,Y=7.000000, Z=4.000000.
