Question

consider the following series of arithmetic expressions.
( a = 2 );
( b = 3 );
( c = 6 );
( a = a + 12 / b );
( b - );
( c += 3 - c );
which of the following statements is true?
( a == 6 ) and ( b == 2 ) and ( c == 3 )
( a == 4 ) and ( b == 2 ) and ( c == 3 )
( a == 6 ) and ( b == 2 ) and ( c == -3 )

Explanation:

Step1: Calculate the value of \(a\)

Given \(a = 2\), \(b = 3\), and the expression \(a=a + 12/b\).
Substitute the values: \(a=2+\frac{12}{3}=2 + 4=6\).

Step2: Calculate the value of \(b\)

Given \(b = 3\), and the expression \(b--\) (post - decrement).
After \(b--\), the value of \(b\) becomes \(2\).

Step3: Calculate the value of \(c\)

Given \(c = 6\), and the expression \(c+=3 - c\).
First, calculate \(3 - c=3 - 6=-3\). Then \(c=c+(3 - c)=6+( - 3)=3\).

Answer:

\(a == 6\) and \(b == 2\) and \(c == 3\)
