fread() - Want to read an integer but it is returning garbage

I have a dynamic .txt file called library.txt, which has only one line of data. It is exactly this one: 

63Book Title1|Book Author 1|Book Editor 1|2014|English|255|99.989998|

I'm trying to read the first integer on the file (in this case, the number "63") using the void readInteger() function that I created: 

void readInteger(){
FILE *arq = fopen("library.txt", "r+");
if(arq == NULL){
    printf("ERROR WHILE OPENING FILE!!!");
    return;
}

int x;
fread(&x, sizeof(int), 1, arq);
printf("%d", x);
return;
}

But the function always keep printing the crazy number "1866609462".
Does anyone know what is wrong with my code? Can you guys help me please?

fread is not the right function to use to read formatted data. Use fscanf instead.

fscanf(arq, "%d", &x);
