Call-by-value parameters:
b and c.
An annotated flowchart includes:
a and c.
The last step in problem solving is to evaluate the solution. This means
To check if the set of step by step instructions developed in step 5, list instructions that enable you to solve the problem, solve the problem identified in step 1.
Cohesion relates to:
The functional independence of each module.
Data can be made available to other modules through the use of:
All of the above.
A problem that requires a heuristic solution might be:
Choosing stock on the stock market.
In the expression 4 + 10, the operand(s)
are the 4 and the 10.
Step 4 is to select the best way to solve the problem. This means:
All of the above.
An example of data found in a file would be:
A quantity
Step 3 in problem solving is to identify alternative ways to solve the problem. This means:
To identify as many solutions as possible to the problem.
Computers can best deal with problems that require:
Reasoning.
External documentation:
Provides communication to the user.
Calculations may be found:
Only in any process modules.
The loop logic structure:
Allows the computer to repeat instructions.
Coupling allows:
Data to be passes from one module to another module.
In an algorithm:
All of the above
Mathematical operators include among others:
MOD, *, ^
In the following expression, what is the order of execution of the operators and the result, given A = 4, B = 5, E = 3, G = True, F = True? A * B + 7 > E ^ 3 OR NOT G AND F
^, *, +, >, NOT, AND, OR : Result is True
When using the problem solving tools, the first one to use is:
PAC Chart.
In the following equation under what conditions would PriorityUse be True? PriorityUse = (ValidCard AND TimeNoted) OR (Computer AND GuestCard)
ValidCard is True, TimeNoted is True, Computer is True, GuestCard is False.
A computer bug is:
An error in a solution.
The sequential logic structure:
Processes instructions in order of listing.
To create a set of instructions to make Otto walk in a figure other than a square, the following instruction(s) would need to be added to the instruction set:
Any of the above
The concatenation of "4" and "10" is:
"410"
Internal documentation:
Provides communication and reminders to the programmer
After you have identified alternative solutions
You are ready to evaluate the solution(s).
A variable:
All of the above.
When a flowchart does not fit on a page:
Use off page connectors.
In a flowchart the diamond indicates:
A decision.
The values of local variables:
Are defined within the calling module....
The set of step-by-step instructions written for the solution to a problem must:
Be within the knowledge base of the problem.
An ideal variable name for a client name is:
Client_name
When a module is processed:
The computer jumps to the module, executes the instructions in the module, and then quits.
A parallelogram in a flowchart represents:
Input or Output.
The resultant of A OR B
Is always true except when A and B are both false.
The Problem Analysis Chart:
Has Four parts: the given data, the required results, the processing required, and the solution alternatives
The decision logic structure:
Allows the computer to make a choice of two paths to follow.
In the equation: R = A + B * 2 - (C + 4) / A, the operands are:
A, B, C
An algorithm is:
The set of step by step instructions to solve the problem.
String data:
Is group of characters.
To identify the best alternative solutions you should:
Use other people's ideas as well as your own.
The algorithms:
Is the set of step by step instructions divided into the specific parts, or modules.
Evaluate the following equation for R, given A = 4, B = 5, C = 8 is: R = A + B * 2 - (C + 4) / A
11
Testing the solution:
Provides a validation of the solution.
The variable names in the formal and actual parameter listings:
Must be the same
The data dictionary is:
A list of definitions and attributes of the variables used in the solution.
If the operands are both numerical, and the operator is relational, the data type of the resultant is:
Logical.
A coupling diagram shows:
How the data is passed from one module to another.
The solution to a problem is
All of the above.
The IPO chart:
All of the above.
