Question

I have a text file with machine code in this form:
B2 0A 05
B2 1A 01
B3 08 00 17
B2 09 18

where an instruction has this format:
OP Mode Operand

Note: Operand could be 1 or 2 bytes.

Where:(example)
OP = B2
Mode = 0A
Operand = 05

How can I read the bytes in a variable? As shown in the above example.
When i read the file I get individual characters. I have an array of pointers where I read individual line, but still cannot solve the problem of reading a byte.

Any ideas,suggestions.

I hope I am not confusing anyone here.

Thank you.

Consider using fscanf. You can use the %x format specifier to read hexadecimal integers.
