Answer: "printf" is used to print formatted output to the standard output (usually the console).
2. Question: How do you declare a variable in C?

3. Question: What is the purpose of the "if" statement in C?
Answer: The "if" statement is used for conditional execution. It allows you to execute a block of code only if a specified condition is true.

6. Question: What is the purpose of the "for" loop in C?
Answer: The "for" loop is used for iterative execution. It allows you to repeatedly execute a block of code for a specified number of times.

Answer: You can read user input using the scanf function for formatted input or gets function for unformatted input.
8. Question: What is the difference between "while" and "do-while" loops in C?
Answer: Both loops are used for repetitive execution, but the "do-while" loop guarantees that the code block will execute at least once, as it checks the condition after the first iteration.
9. Question: What is the purpose of the "switch" statement in C?
Answer: The "switch" statement is used for multi-way branching. It allows you to select one of several code blocks to execute based on the value of an expression.
10. Question: What is the role of the "return" statement in a C function?
vbnet**Answer:** The "return" statement is used to exit a function and return a value (if the function has a return type). It also transfers control back to the calling function.
