10 Questions
Explain the difference between an interpreter and a compiler.
An interpreter executes code line by line, while a compiler translates the entire program into machine code before execution.
What is the purpose of the printf() function in C?
The printf() function is used for formatted output in C programs.
Compare static typing in C with dynamic typing in Python.
C is a statically-typed language, meaning variable types must be declared explicitly, while Python is dynamically-typed, allowing variables to hold different data types without explicit declaration.
Explain the scope of variables in C according to their block.
In C, variables have block scope, meaning they are accessible only within the block (delimited by curly braces) in which they are declared.
What is the difference between the while loop and the do-while loop in C?
The while loop checks the condition first before executing the loop body, while the do-while loop executes the loop body at least once before checking the condition.
How are one-dimensional arrays declared and initialized in C?
One-dimensional arrays in C are declared by specifying the data type and size, e.g., int arr[5];. They can be initialized during declaration, e.g., int arr[5] = {1, 2, 3, 4, 5};.
Explain the purpose of the break statement in C loops.
The break statement is used to exit a loop prematurely when a certain condition is met.
What is the purpose of the getch() function in C?
The getch() function is used for character input in C without requiring the user to press the Enter key.
Explain the concept of operator precedence and order of evaluation in C.
Operator precedence determines the order in which operations are performed in an expression, while the order of evaluation specifies the order in which operands are evaluated.
What is the purpose of the sizeof operator in C?
The sizeof operator is used to determine the size (in bytes) of a data type or variable in C.
This quiz covers the basics of C programming including program structure, comments, compilation, formatted I/O, data types, and variables. It also compares these concepts with Python, focusing on static typing in C vs dynamic typing in Python, variable declaration and scope, and hierarchy of data types.
