A*=++a/6+b++ 3 if a=3,b=4​
Vinil7 [7]

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

Create the main function and declare the variables.

Then, use the cout instruction and print the message on the screen.

cin store the string enter by the user into a variable.
