To replace the old quantity value by a new value, set the file pointer to point
to the quantity..
previously when u retrieve the old value, u'll know at which position(index)
qnty is present..
set file pointer using this index as,
FILE * fp=fopen("somefile","w");
fseek(fp,index,SEEK_SET); //seeks position from beginning of file
fprintf("%d",qnty); // put new qnty value
