a) Inputs passed to a program when it is executed
b) Variables defined inside the
main() functionc) Memory addresses of functions
d) Pointers to global variables
Answer:
a) Inputs passed to a program when it is executed
Explanation:
Command line arguments in C are inputs passed to a program when it is executed from the command line. These arguments are typically used to influence the program’s behavior without requiring user interaction during execution. The main() function in C can accept two parameters: int argc, which represents the number of arguments, and char *argv[], an array of strings representing the arguments themselves. Command line arguments are commonly used for tasks such as configuring program options, specifying file paths, and passing data to the program at runtime.
Understanding command line arguments is essential for writing flexible and user-friendly C programs that can be configured and executed with different input parameters.
