Writing an integer into a file

Hi,

I am new to C programming. I am trying to write an integer into a file using built-in fwrite function in C. After writing the integer into file it becomes unreadable(^@^@.. characters). Can you please let me know how to write an integer into a file so that it is readable ?. I am using the following code.

Code:

---

void main(){
    int a = 10;
    int *p = &a;
    FILE *fp = fopen("Ascii.txt", "w");
    fwrite(p,sizeof(int),1,fp);
    fclose(fp);
}

What did you expect? There's a difference between the integer value 10 and its textual representation in ASCII. Use fprintf with the %d specifier if you want the integer to written as ASCII text.

fwrite is for binary data. Normal text data is handled by

Code:

---

fprintf(NameOfFilePointer, "%d", myIntegerVariableName);
