Correct Answer : Arguments passed to main() function
Explanation :
The most important function of C/C++ is main() function. It is mostly defined with a return type of int and without parameters :
int main() { /* ... */ }
We can also give command-line arguments in C and C++. Command-line arguments are given after the name of the program in command-line shell of Operating Systems.
To pass command line arguments, we typically define main() with two arguments : first argument is the number of command line arguments and second is list of command-line arguments.
int main(int argc, char *argv[]) { /* ... */ }
or
int main(int argc, char **argv) { /* ... */ }
