C# Programming Concepts Practice Test

What are the two primary types of memory allocation in programming?

• Temporary and permanent memory allocation

• Static and dynamic memory allocation

• Automatic and manual memory allocation

• Local and global memory allocation

Describe how a stack trace can assist a programmer in identifying issues within their code.

• A stack trace shows the sequence of function calls leading to an error, helping to locate the source of the problem.

• A stack trace lists all variables in the program.

• A stack trace displays the memory usage of the program.

• A stack trace indicates the performance of each function.

Which type of structure is used to determine which of two sets of instructions to execute?

• Nested structure

• Decision structure

• Sequence structure

• None of these

• Do together structure

Conducted by users without knowledge of any expected outcomes

• Conducted by users without knowledge of any expected outcomes

• Involves detailed knowledge of the internal code

• Requires access to the source code

Describe the characteristics of static memory allocation as it pertains to stack usage in programming.

• Static memory allocation is only used for global variables.

• Static memory allocation allocates a fixed amount of memory at compile time, which is used by the stack during program execution.

• Static memory allocation can be resized during program execution.

• Static memory allocation allows for variable-sized memory allocation during runtime.

Describe the role of an IF statement in controlling the flow of a program.

• An IF statement allows a program to execute certain code only when specific conditions are met, thus controlling the flow of execution based on logical evaluations.

• An IF statement creates a loop that runs indefinitely.

• An IF statement is used to declare variables in a program.

• An IF statement is solely for error handling.

What is the primary purpose of using flowcharts in software development?

• To manage memory allocation in the application.

• To write code directly for the application.

• To visually represent the logic flow of an application.

• To handle errors in the application.

Describe how garbage collection contributes to memory management in C#.

• Garbage collection prevents memory leaks by allocating more memory.

• Garbage collection requires manual intervention to free memory.

• Garbage collection is only necessary for large applications.

• Garbage collection helps manage memory by automatically freeing up space occupied by objects that are no longer needed.

What is the term used when a function calls itself in programming?

• Abstraction

• Compilation

• Iteration

• Recursion

What is the definition of immutability in programming?

• A variable that holds a reference to another variable.

• A variable that can be changed at any time during execution.

• A variable that cannot be changed once the code is compiled and the application is running.

• A variable that is only accessible within a specific function.
