Question

You are required to open a file for input and read the data in that file into an array (named data). Use the variable size to count how many elements in the file. Create the file yourself in notepad and call it data.txt so that it has the following numbers in order: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0

Please help with this. In C please

#include <stdio.h>

int main() {
    FILE *fp = fopen("data.txt", "r");
    if (fp) {
        int data[1000], size = 0, num, i;
        while (fscanf(fp, "%d", &num) != EOF) {
            data[size++] = num;
        }
        // print data in array
        printf("Numbers read from file are:\n");
        for (i = 0; i < size; ++i) {
            printf("%d\n", data[i]);
        }
        fclose(fp);
    } else {
        printf("data.txt does not exists!\n");
    }
    return 0;
