Basics of C
What is `.c`?
This is the file extension used for C source code files.
What is an `if` statement?
This conditional structure executes a block of code if a specified condition is true.
What is `int`?
This is the typical return type for the `main()` function in C.
What is `*`?
This symbol is used to declare a pointer
What are the 4 pillars of computational thinking?
decomposition, pattern recognition, abstraction, and algorithmic thinking
What is `#include `?
This directive allows access to standard input/output functions like `printf` and `scanf`.
What is a `do-while` loop?
This loop executes at least once, even if the condition is false
What is a local variable?
This variable type is declared within a function and only accessible inside it.
What is `NULL`?
This special value means a pointer doesn't point to any memory location
Define abstraction in computing
This concept means hiding unnecessary details to focus on important information.
What is `int`?
This keyword is used to declare a variable that stores integer data.
What is a `for` loop running 5 times from i = 0 to 4?
This loop structure runs a block five times: `for(int i=0; i<5; i++)`
What is `void`?
This keyword means a function does not return any value
What is the address-of operator `&`?
This operator is used to pass a variable by reference to a function
what is decomposition?
This technique involves breaking down a problem into smaller parts.
What is `scanf()`?
This function is used to take input from the user in C.
What is the `else` clause?
If this part of an if-else is missing, only the "if" part will execute if true
What is variable scope?
This determines which functions can access a variable
What is dereferencing an uninitialized pointer?
This causes a runtime error if a pointer is used before it's assigned.
What is pattern recognition?
This is the process of finding similarities in problems or solutions.
What is the compilation process (preprocessing, compiling, assembling, linking)?
This multi-step process converts C code to machine code.
What is a `switch` statement?
This control structure can sometimes replace a chain of `if-else` statements
What is the call stack?
This is where function call data is stored during execution.
What are stack and heap memory?
These are the two types of memory allocation in C.
What is algorithmic thinking?
This skill involves designing a step-by-step plan to solve a problem, like solving a maze.
