It seems that you are confused about hexadecimal and binary notations. Those are only representations of a number, and they don't have any influence on the number. In your example, t has a value of 86 (decimal), 0x56 (hexa) and 0b01010110(binary). These are different representations of the same number. So, your question is wrong, you simply want to convert a number to it's corresponding ASCII representation.
For that part, it is easy: simply store the value in a character and print it. It will be automatically displayed as a character (thus, using the symbol in the ASCII table).
But, where do you want to display this character ? Because here also, the ASCII representation is just a way to represent a character. The value contained in the variable doesn't change (it is still 86).

What are you asking for?
If you need the hexadecimal representation of (say) a byte then you may use sprintf, for instance:
char buf[10];
unsigned char c = 65;
sprintf(buf, "%02X",c);
printf("%s\n");
outputs
41

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

here i want output print A
so please tell me how can i do this

printf("%c\n", c)
Are you really asking for this?

I think you should spend some time studying this paper[^] and any others on the same subject. You seem to be working on programming with very little understanding of how information is held and manipulated in a computer - either because you have missed something in your education or because you are very young.
It's time for a new signature.

Hi Friends
I need to implement "Pages Per Sheet " option ( The same option as in MS Word Print Dialog ) in Applications Print Dialog . My Application is written in VC++ and MFC .
I searched in the net ,but I am not getting any Information on how to implement .
I would be really grateful,if I can get any inputs on how I can proceed .
Regards,
Jack

I have never used this but I would assume you need to do some calculations based on this value to resize your logical page. You then need to scale your output to the size of the new logical page and set your start point for each page to its relative position on the physical page. I usually start with problems such as this by drawing a rough representation on a sheet of paper and figure it out from there.

Thanks Richard for the inputs............I will try to do as you have suggested..........

Hi
I am designing an amplifier where I've used I2C to communicate with two control circuit PICs (pic18f819) and then those PICs are also communicating to an-other PIC (same) via serdata serclck. The pull up voltage is 3.9 on one side of the pull-up resistors and appears 2.5 on the other side on I2c line while on ser line 2.5 on serdata and 0v on serclck. The PCB used to communicate but suddenly it is not communicating now. Is it because of 2.5 voltage appearing on I2C OR 0v on serclock OR thses pull up voltages drops dont matter ? can some one help please. I'm not sure about 2.5v on I2C and also what voltages are necessary for serdata/serclcl line ?

I really don't think our expert C/C++ programmers can help you with what is clearly a hardware problem.

I2C uses four basic clocks START, DATA, ACK and STOP. It is the combination of SDATA and SCLK. Check the impedance and threshold limit of chip to get signal.

As others have stated you are in the wrong forum but anyway ..... if you are ever concerned about voltage levels in circuit you need to refer to the manufacturer's Data Sheet specifically the the Input Voltage thresholds. It will tell you the minimum voltage that is guaranteed to be recognised as a logic 1 and the maximum voltage that is acceptable as a logic 0. That should answer your question.
Hope that helps

Hi,
please tell me how to convert from hex to Ascii.
thanks.
|
|
|
|
|
Is the hex value stored as character strings?
If so use this formula for a 2 digit hex - (16 * A) + B where A is the digit on the left and B is the digit on the right.
|
|
|
|
|
This doesn't make a lot of sense. Hex is just a representation of a number. Is this what you want to do: you have a string containing two characters (in hex representation) and you would like to display the character from the ASCII table ?
If yes, you can use strtoul[^] to convert the number to an unsigned long and then assign it to a char (probably with a cast to avoid a warning).

Hi, everyone
I want to use database in my application , but when I add #include <afxdb.h> to the stdafx.h, it give me the above error message.
When I change the position of the #include<afxdb.h>, it give me other error message,
error C2146: syntax error : missing ';' before identifier 'ConvertToWin32ALG_ID'
so what is the problem?
the following code is the the stdafx.h file
// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently,
// but are changed infrequently
#if !defined(AFX_STDAFX_H__3D0D8E67_10EC_4002_9AE7_E8E9AE644C83__INCLUDED_)
#define AFX_STDAFX_H__3D0D8E67_10EC_4002_9AE7_E8E9AE644C83__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#define STRICT
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0400
#endif
#define _ATL_APARTMENT_THREADED
#include <afxdb.h>
#include <atlbase.h>
//You may derive a class from CComModule and use it if you want to override
//something, but do not change the name of _Module
extern CComModule _Module;
#include <atlcom.h>
//used for token
#include <pkcs11/cryptoki.h>
#include <pkcs11/auxiliary.h>
#define PKCS_LIB_NAME "ST2pkcs11v10.dll"
#define ArraySize 1000
//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.
#include <comdef.h>
