Answer: An example of such a scenario would be when the user name and password meant to allow access to a customers bank account statement is cracked by unauthorized people this causing alteration (in the form of data diddling attacks) in the data contained in the statement. This is a compromise in integrity.
Explanation:
Confidentiality entails securing things people want to remain secret. An account statement of a bank customer is a confidential document which is to be kept secret. A password allows access to it.
Integrity implies receiving a sent data/information as accurately as it came from a sender. A data diddling attack alter integrity because the original information is altered by an unauthorized person.
Answer:
Following are the definition of function
double averager (const double &x) // function definition
{
static double z = 0.0; // variable declaration
static size_t c = 0;
c=c+1; // increment of c by 1
z =z+ x; // adding value
return z /c ; // return average
}
Explanation:
Following are the description of statement
- Create a function averager of double type that holds a parameter "x" of the double type .
- In this function we declared a variable "z" of a static double type that value is initialized by 0.
- The static variable is used to retain value.
- Declared a variable "c" of size_t type that holds a value 0 .
- After that increment the value of c by 1 .
- adding the value of "z" variable to the "x" and storing the result into the z variable.
- Finally return the average value
