用C将数组写到文件中？

FILE *file = fopen("filename.txt", "w");
if (file == NULL) {
    printf("无法打开文件\n");
    return;
}

int array[] = {1, 2, 3, 4, 5};
int size = sizeof(array[0]);
int count = sizeof(array) / size;

fwrite(array, size, count, file);

fclose(file);

#include <stdio.h>

int main() {
    FILE *file = fopen("filename.txt", "w");
    if (file == NULL) {
        printf("无法打开文件\n");
        return 1;
    }

    int array[] = {1, 2, 3, 4, 5};
    int size = sizeof(array[0]);
    int count = sizeof(array) / size;

    fwrite(array, size, count, file);

    fclose(file);

    return 0;
}
