My array does not reset to zero after I recall the function - c

Question

I'm writing a word, character, line counter for files in C. Im using a function get_counts to get these numbers. Right now I'm trying to get these values for two files. However, when I call it twice, the values don't reset to zero. I don't understand why because I declare the array to be {0,0,0} before I do any counting when I call the function. Here is my code. Currently just trying to get the line counter to work in print_counts. i'm sending it two files, one file has 3735 lines and the other file has 21. I keep getting an output of 3756.
int *get_counts(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;
}
void print_counts(int* show, int *count, char *name)
{
if (name[0] != '\0')
{
//int *myArray1 = get_counts(&name[0]);
if (show[0] == 1)
{
printf("%d", count[0]);
}
}
if (name[1] != '\0')
{
if (show[0] == 1)
{
printf("%d", count[0]);
}
}
}
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("error");
exit(1);
}
}
int *myArrayAlice = get_counts(nameArray[0]);
print_counts(argArray, myArrayAlice, *nameArray);
int *myArrayAnh = get_counts(nameArray[1]);
print_counts(argArray, myArrayAnh, *nameArray);
return 0;
}

I don't understand why because I declare the array to be {0,0,0}
before I do any counting when I call the function.
Because is defined as static, remove the static keyword switching to int *arr = calloc(3, sizeof(int); or passing arr[3] from main and calling memset(arr, 0, 3 * sizeof(int)); in the function if you prefer to avoid dynamic memory.
