Hi all, i am new to this forum, and i am a C beginner... can anyone tell me that how to read 2 bytes of data from a file and have that in a single variable ??? thank u...
thanks for the reply shabbir, i will tell my problem more specifically.... i have a hex file and i wanted to read 2nd and 3rd bytes of that file which contains some information about some size... i want that size to be extracted in a single variable.....please help me thanks...
Read second byte into a char say an array of 2 elements x[0] and 3rd byte into char x[1]. Convert them to int and then combine both the bytes using atoi function
thanks shabbir, i tried that... but by using atoi only integers will be displayed...what if the values stored are in HEX say...A,B....F... atoi function will not recognize this ??? am i right ??
sorry i didnt get u ??? say i have 3 and A(hex value) in the second and third locations of the file... by using atoi it only recognizes it as 3 ......and A is truncated right ???
You are reading 3 now convert it to integer. which will be 3. Now read A, Convert it to int which will be 10 Now combine them using atoi function. Probably I wasnt clear in my previous post but I think this should.
thanks shabbir... but if the value is 3A i have to read that as 16*3+10=58..... how can i do this....
I guess it should go like read the string as Hex like 3A. Now convert the 3A using the Decimal, Hex, octal and binary number inter conversion. 3A in Hex is equivalent to 58 in Decimal and so you dont need to go about reading the bytes and then converting.
oh... fine codes... thanks shabbir... i will come back if i have some moere doubts... thanks again....
