Question

a*=++a/6+b++ 3 if a=3,b=4​

Answer 1

Answer:

$a=22.5$

Explanation:

Given

$a*=++a/6+b++3$

Required

The result when $a=3$ and $b=4$

Analyzing the given instruction

a*=(++a)/(6)+(b++3)

Single out and solve the expressions in bracket

(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.

So: in this case: ++a = a

$b++3 = b + 3$

The operator, as used in that statement is the same as: b + 3.

So:

$a*=(++a)/(6)+(b++3)$

$a*=(a)/(6)+(b+3)$

$a*=(3)/(6)+(4+3)$

$a*=0.5+7$

$a*=7.5$

The above expression is calculated as:

$a=a*7.5$

So:

$a=3*7.5$

$a=22.5$
