Which of the following is the correct syntax using the compound assignment operator to multiply variable x by 5 and assign the result back to x?

Ax = x *5;

Bx =* 5;

Cx = *5;

Dx *= 5;

Step-by-Step Solution

Solution:

Step 1: Identify correct compound assignment syntax
The correct syntax for multiplying and assigning is 'x *= 5;'. It combines multiplication and assignment.

x =* 5; 'x =* 5;' is invalid syntax. x = *5; 'x = *5;' is invalid because '*5' is not a valid expression. x = x *5; 'x = x *5;' is correct but not a compound assignment operator.
Final Answer:
x *= 5; -> Option D
Quick Check:
