hi all ,
i have a program that read its input from a file in binary mode!
now i nead to store this data and to compare it with another data.
which datataype can my input take.

also, the comapred stream is in this form 0004a4900
i made this stream as a cons int and then with 0x it is already stored as an hex. stream
now when i read i want to search this strream in my input file

>which datataype can my input take.
The same data type you used to write it if you want a meaningful comparison. If you're just checking for equality, you can use unsigned char and compare every byte individually.

There's no question here.

unsigned char is for byte or what!!
i mean what is the difference between char and unsigned char?

>i mean what is the difference between char and unsigned char?
char isn't portable because it could be either signed or unsigned.

and what does unsigned char mean?

is each byte 'll read as an unsigned char?
