Thread: fill unsigned char array with hex values

im trying to fill an unsigned char array with hex values (0x12 0x23 etc)
read in from a text file, i have searched this forum, but not found exactly what i need and my limited knowledge prevents me from adapting the code snippets i found to my needs. the code snippet i have is as follows, i am not posting the whole program because previously i have been flamed for doing that.

Code:

 FILE *file;
    U8 instructions;
    U8 hexbyte = 0x00;
    U8 hexnibh = 0x00;
    U8 hexnibl = 0x00;
    U8 memory[10] = {0x00};
    U8 progmemory[10] = {0x00};
    U8 convert = 0x00;
    U8 i = 0x00;
       

    file = fopen("f:\\L_Endian.txt", "r");

    while(! feof(file)){
    fscanf(file, "%c", &memory[instructions++]);
        hexnibh=memory[convert++];
        hexnibh =(hexnibh - '0');
        hexnibh = (hexnibh << 4);

    fscanf(file, "%c", &memory[instructions++]);
        hexnibl=memory[convert++];
        hexnibl =(hexnibl - '0');
        hexbyte = (hexnibh ^ hexnibl);
        progmemory[i++] = hexbyte;
    }
    fclose(file);

what i want to do is read in a file with numbers like 1234567890...
convert to hex values
into an array[0x12]
array[0x34]
array[0x56]
array[0x78]
array[0x90]

each element being an unsigned char type
this code nearly works except i get extra (unwanted)byte 0x0A and in the array

if thas has been done allready can you point me to the location please
