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

D. Fault tolerance

Explanation:

  • Fault Tolerance basically refers to the feature or capability of a  system to keeps on working and performing its operations without interruption in case of a failure.
  • This failure can be the failure of one or more of its components.
  • This is beneficial as the system does not stop working or fail completely.
  • It provides copies of the same system or backup components which can be used when the existing system fails and prevents the loss of information and services.
  • Accessibility  refers to provide equal services for everyone who uses a system. So its not a correct option.
  • Moore’s law states that the computing speed and power will double every two years so its not a correct option as well.
  • Anti virus is a software to identify, prevent and remove viruses and malware so it is not a correct option as well.
