Which statement is true about function arguments in C?

• A. They can only be passed by reference
• B. They cannot be modified within the function
• C. They are specified in the function declaration
• D. They must always be of the same type

Answer: (C)

The statement that function arguments are specified in the function declaration is true. In C programming, when you define a function, you specify its parameters—these are the function arguments that the function can accept when it is called. This specification includes the data type of each parameter, allowing the compiler to understand what kind of values (e.g., integers, floats, characters) can be passed to the function. This is essential for type checking during compilation, ensuring that the arguments provided in a function call match the expected types as defined in the function declaration. For example, a function declaration might look like this: ```c int add(int a, int b); ``` Here, the function `add` is declared to accept two integer parameters, `a` and `b`. Later, when calling this function, the arguments passed must be integers, or the code will result in a compilation error, demonstrating the importance of correctly specifying function arguments in the declaration. The other options do not accurately reflect the nature of function arguments in C. The ability to pass by reference or by value pertains to how data is passed, and arguments can be modified depending on how they are passed. Additionally, arguments do not all have to be of the same type; functions can
