Program Plan Intro
Testing:
- It denotes an activity to check whether actual results match expected results.
- It guarantees that software system is defect free.
- It involves execution of a software component for evaluating one or more interest properties.
- It identifies errors, gaps or requirements that are omitted related to actual requirements.
- It could be performed manually or using automated tools.
- It can be classified as white or black box testing.
- The manual testing would include testing of software short of any tool.
- The tester behaves as an end-user.
- It tests software for identifying any behavior that is unexpected.
- The different stages include unit, integration, system as well as user acceptance testing.
- The automation testing uses software to test product.
- It includes automation for a manual process.
- The test scenarios are been re-run that are been performed manually.
- It is used for testing application from performance, load in addition to stress view point.
Driver
- The driver program contains program’s main function.
- It is responsible for launching program operations.
- It is responsible for converting user program into physical execution unit termed as task.
- Each function must be designed, tested and coded as a discrete unit from rest of program.
- It denotes a testing program for functions or statement that is been written in code.
- It tests the functionality usually for debugging as well as code verification.
Given addTax function:
//Define method addTax
void addTax(double taxRate, double& cost)
{
//Compute cost
cost = cost + ( taxRate/100.0 ) * cost;
}
Explanation:
- The method “addTax()” takes input values as arguments.
- It computes the cost by using input values entered by user.
- The result of operation is been displayed.

Write the definition of a void function that takes as input two parameters of type int, say sum and testScore the function updates the value of sum by adding the value of testScore. The new value of sum is reflected in the calling environment.
Do you have to use the template prefix for each function in the class defini- tion? Do you have to use the template prefix for each function in the class implementation?
Write a function which takes two integer parameters for values to be added together
and returns the result by value. The function may not print anything or read anything
directly from the user (i.e. no cin/cout in the function). Assume that the values passed
to the function will not be negative, but could be 0 or positive, and will both be integers.
The function must implement addition recursively, and cannot use the standalone +
operator (only ++) or call any other functions.

- Suppose that an array is passed as a parameter. How does this differ from the usual use of a value parameter? When an array is passed as a parameter, it is like passed by reference. A new array will be created in the called function and any changes to the new array will pass back to the original array. When an array is passed as a parameter, it is passed by value. So any changes to the parameter do not affect the actual argument. When an array is passed as a parameter, changes to the array affect the actual argument. This is because the parameter is treated as a pointer that points to the first component of the array. This is different from a value parameter (where changes to the parameter do not affect the actual argument). When an array is passed as a value, changes to the array affect the actual argument.
