C:使用fwrite将char写入不同的行

int main() {
    char *data;
    int count = 0;
    FILE *fp;

    fp = fopen("output.txt", "w");

    if (!fp) {
        printf("Error opening file\n");
        return 1;
    }

    while (count < 10) {
        data = (char *)malloc(10);
        if (!data) {
            printf("Memory allocation failed\n");
            return 1;
        }
        strcpy(data, "Line ");
        strcat(data, count);
        printf("Writing %s to file\n", data);
        fwrite(data, 1, strlen(data), fp);
        free(data);
        count++;
    }

    fclose(fp);
    return 0;
}

int main() {

    FILE *fp;

    fp = fopen("output.txt", "w");

    if (!fp) {

        return 1;
    }
