What is wrong with the following while repetition statement?
while ( z >= 0 )
sum += z;

The value of the variable z is never changed in the while statement. Therefore, if the loop continuation condition (z >= 0) is initially true, an infinite loop is created. To prevent the infinite loop, z must be decremented so that it eventually becomes less than 0.

We can’t use name sum for variables, because it is a C++ keyword.

The value of the variable z is never changed in the while statement. Therefore, if the loop continuation condition (z >= 0) is initially false, an infinite loop is created. To prevent the infinite loop, z must be incremented so that it eventually becomes greater than 0.

The value of the variable sum is never changed in the while statement. Therefore, if the loop continuation condition (z >= 0) is initially true, an infinite loop is created. To prevent the infinite loop, sum must be decremented so that it eventually becomes less than 0.

Explain the purpose of a function parameter. What is the difference between a parameter and an argument?

A parameter represents additional information that a function requires to perform its task. Each parameter required by a function is specified in the function header. An argument is the value supplied in the function call. When the function is called, the argument value is passed into the function parameter so that the function can perform its task

A data member is declared in a class definition, but not in the body of any of the class's member functions. Every object (instance) of a class has a separate copy of the class's data members. Also, data members are accessible to all member functions of the class.

Why would a function prototype contain a parameter type declaration such as double &?

This creates a reference parameter of type "reference to double" that enables the function to modify the original variable in the calling function

This creates a reference parameter of type "reference to double" that enables the function to modify a copy of the original variable in the calling function

This creates a reference parameter of type "reference to double" that makes code safer and doesn’t let the function to modify the original variable in the calling function

Error: The second error occurs in function getCount. This function is declared static, so it is not allowed to access any non-static member of the class.
Correction: To correct the second error, remove the output line from the getCount definition.

Error: The class definition for Example has one error. It occurs in function getIncrementedData. The function is declared const, but it modifies the object.
