In C programming, which category of characters would include `!`, `@`, and `$`?

• Digits
• Keywords
• Special Characters
• Letters

Which statement correctly describes the use of keywords in C programming?

• Keywords can be used interchangeably with identifiers.
• Keywords are primarily used for comments in the code.
• Keywords are names given to variables by the programmer.
• Keywords are reserved words with special predefined meanings.

A programmer wants to name a variable for a customer's total orders. Which of the following is a valid identifier in C?

• 1st_order
• if
• customer_orders
• total-orders

Why is selecting the correct data type important when declaring a variable in C?

• It dictates whether the variable can be modified or not.
• It automatically initializes the variable to a random value.
• It specifies the kind of data the variable can store.
• It speeds up the program's execution by 50%.

To store the precise value of a calculation involving division, like 10 \div 3 or 3.3333333333, which C data type is generally preferred?

• `char`
• `double`
• `int`
• `void`

Which pair of methods can be used to define a constant in C, ensuring its value does not change?

• Using `auto` or the `typedef` keyword.
• Using `volatile` or the `static` keyword.
• Using `#define` or the `const` keyword.
• Using `register` or the `extern` keyword.

A program declares `int score;`. Which line correctly initializes `score` to zero after its declaration?

• int score = 0;

• score = 0;

• `score -> 0;`
• `0 = score;`

Which characteristic best defines a variable in C programming?

• A named storage location whose value can change.
• A function that performs a specific task.
• A reserved word with special meaning to the compiler.
• A fixed value that cannot change during execution.

The `%` operator in C is used for what kind of mathematical calculation?

• Addition
• Exponentiation
• Multiplication
• Modulus (remainder of division)

A program needs to execute a block of code only if variable `A` is strictly larger than variable `B`. Which relational operator should be used in the `if` condition?

• `>=`
• `==`
• `>`
• `<`
