What is the difference between 'plain text' and 'cipher text' in the context of cryptography?
Press to flip
Plain text is the original readable message, while cipher text is the encrypted message.
Why is understanding low-level details important in programming?
Understanding low-level details is crucial for building efficient and robust complex applications.
What is the exit status of a program and how is it used?
The exit status is a code returned by a program at completion; 0 typically indicates success while non-zero indicates errors. It's used for diagnosing issues and automation.
In the context of command line arguments, what do 'argc' and 'argv' represent?
'argc' represents the argument count, and 'argv' is the argument vector, an array of strings representing the inputs from the command line.
What is the importance of breakpoints in debugging?
Breakpoints allow programmers to pause execution at specific lines to inspect variables and program state, aiding in the debugging process.
What is Rubber Duck Debugging and how does it help with debugging?
Rubber Duck Debugging involves explaining your code logic to an inanimate object, which can help clarify your thinking and reveal overlooked errors.
Explain how the 'clang' command can be used to compile a C program with a specific output filename.
Use the command 'clang -o hello hello.c' to compile the C program in 'hello.c' and output the executable as 'hello'.
What are some factors used to determine reading levels in algorithms?
Word complexity, punctuation, and sentence length.
What is the purpose of the C type library, and give an example of a function it provides?
The C type library provides functions for character manipulation, such as 'toupper' to convert characters to uppercase.
Why might reversing compiled software be problematic in terms of intellectual property?
Reverse engineering might expose sensitive algorithms and logic, potentially infringing on intellectual property rights.
How are strings represented in C, and why is it important to understand their memory layout?
Strings in C are arrays of characters ending with a null terminator ('\0'), which is crucial for understanding how to manipulate and read them correctly in memory.
Describe the steps that occur during the compilation process.
1. Preprocessing: Replace '#include' directives with corresponding code. 2. Compiling: Convert C code to assembly language. 3. Assembling: Convert assembly code to machine code. 4. Linking: Combine machine code from multiple files into an executable.
How does the 'debug50' tool assist in the debugging process?
The 'debug50' tool helps by allowing step-through execution of code and examining program flow to identify errors.
Define what a Caesar Cipher is in cryptography.
A Caesar Cipher is an encryption technique that shifts letters of the alphabet by a fixed number.
What role does the 'make' command play in compiling code?
The 'make' command automates the process of building programs from source code.
