How to skip NULL file - c

Question

My code traverses through command line arguments. if the command line contains "alice.txt" index zero of an empty array is filled with "alice.txt" This also applies to "anh.txt" if it is present, then index 1 is filled with "anh.txt". When i type in the command line ./wc alice.txt anh.txt it will print out words line and characters of both files. however if I just do /wc anh.txt i will get "NULL FILE" I suspect this is because of index zero being NULL, I wrote it so it would print "NULL FILE" and then exit the program. How can I modify my code so it doesn't exit, rather skips to the next index? This is what I have for code:
int main(int argc, char **argv)
{
int argArray[argc];
char *nameArray[argc];
for (int i = 1; i < argc; i ++)
{
if (strcmp(argv[i], "-l") == 0)
{
argArray[0] = 1;
}
if (strcmp(argv[i], "-w") == 0)
{
argArray[1] = 1;
}
if (strcmp(argv[i], "-c") == 0)
{
argArray[2] = 1;
}
if (strcmp(argv[i], "alice.txt") == 0)
{
nameArray[0] = "alice.txt";
}
if (strcmp(argv[i], "anh.txt") == 0)
{
nameArray[1] = "anh.txt";
}
if ((strcmp(argv[i], "-l") != 0) && (strcmp(argv[i], "-c") != 0 ) && (strcmp(argv[i], "-w") != 0 ) && (strcmp(argv[i], "-w") != 0) && (strcmp(argv[i], "alice.txt") != 0) && (strcmp(argv[i], "anh.txt") != 0))
{
printf("%s is an invalid argument or file\n", argv[i]);
}
}
if ((argArray[0] != 1) && (argArray[1] != 1) && (argArray[2] != 1))
{
argArray[0] = 1;
argArray[1] = 1;
argArray[2] = 1;
}
int *myArrayAlice = get_counts2(nameArray[0]);
print_counts(argArray, myArrayAlice, *nameArray);
printf(" alice.txt\n");
int *myArrayAnh = get_counts(nameArray[1]);
print_counts(argArray,myArrayAnh, *nameArray);
printf(" anh.txt\n");
int *myArrayTotal2 = get_counts2(nameArray[1]);
print_counts(argArray, myArrayTotal2, *nameArray);
printf(" total\n");
return 0;
}
int *get_counts(char *filename)
{
FILE *file = fopen(filename, "r");
if (file == NULL)
{
printf("NULL FILE");
//exit(1);
}
int c;
bool whitespace = true;
int *arr = calloc(3,sizeof(int));
for(;;)
{
c = fgetc(file);
if (c == EOF)
{
break;
}
else if (c == '\n')
{
arr[0]++;
}
else if (whitespace && !isspace(c))
{
arr[1]++;
whitespace = false;
}
else if (!whitespace && isspace(c))
{
whitespace = true;
}
arr[2]++;
}
fclose(file);
return arr;
}
int *get_counts2(char *filename)
{
FILE *file = fopen(filename, "r");
if (file == NULL)
{
printf("NULL FILE");
//exit(1);
}
int c;
bool whitespace = true;
static int arr[3] = {0,0,0};
for(;;)
{
c = fgetc(file);
if (c == EOF)
{
break;
}
else if (c == '\n')
{
arr[0]++;
}
else if (whitespace && !isspace(c))
{
arr[1]++;
whitespace = false;
}
else if (!whitespace && isspace(c))
{
whitespace = true;
}
arr[2]++;
}
fclose(file);
return arr;
}
