[SOLVED] How do you add command line arguments for specific use to your terminal in Ubuntu?

Issue

I'm a bit confused as to how I could add certain parameters in the Ubuntu terminal when using the GNU C compiler to compile the program. For example:

gcc -o question question.c
./question -e -f someFile.txt 

where -f would open this specific file 'someFile.txt' (any file) and -e would let me access a specific function inside my code. I tried this with void main(int argc, char* argv[]) but with that I would have to specify the number of arguments I would have to pass i.e. ./question 3 -e -f resources.txt, which I would not like to do.
Is there any other way I could attempt this? Thank you in advance!!!

Solution

#include <stdio.h>

int main(int argc, char **argv) {
    printf("program was supplied %d arguments.\n", argc - 1);
    for (int k = 0; k < argc; k++) printf("argv[%d] is %s\n", k, argv[k]);
    if (!strcmp(argv[1], "-e")) printf("The first argument provided is -e\n");
}
