The way I read this, you want to #include "sc.h" in frst.h and #include "th.h" in sc.h, but not #include "frst.h" in th.h? WQell, surely you just need to put the appropriate #include lines in frst.h and sc.h as below?

Put this line at the start of frst.h

#include "sc.h"

Put this line at the start of sc.h

#include "th.h"

More information might be useful, but I'd suggest reading about Forward Declarations[^] as a good place to start.

Right, I'll do it with forward declaration. Thanks for answers.

Switching on and setting baud rate [modified]

Hi all, I am new to the forum. I am currently using C program to communicate with PIC18F2620 and using TR800 to transmit text message to hand phone. I am trying to power on, reset and set the baud rate without using Hyper terminal. I am currently having some difficulty in doing that. Any help would be gratefully appreciated. Thanks in advance. Below is the code snippet.

void setup_gsm(void)
{

        //setup_gsm
	// turn on the telit module and verify, else reset autobaud
	PWON = 1;
	Delay10KTCYx(40);
	// reset ram pointer
	RESET = 0;
	// AT command test
	// response: AT
	putrsUSART ((const far rom char *)"AT\r");
	Delay10KTCYx (50);
	// set_baud
	RESET = 0;                     
	// set_baude_rate 300,1200,2400,4800,9600,19200......
	// response: OK
	putrsUSART ((const far rom char *)"AT+IPR=115200\r");
	Delay10KTCYx (50);
	// disable_echo
	RESET = 0;
	// Disable echo command
	// response: OK
	putrsUSART ((const far rom char *)"ATE=0\r");        
	Delay10KTCYx (50);                                              
	// caller_id.
	RESET = 0;
        // Set CALLER ID; 1=on
	// response: OK
	putrsUSART ((const far rom char *)"AT+CLIP=1\r");
	Delay10KTCYx (10);
	// error_code
	RESET = 0;
	// Enable extended error code ; 1 =numeric
	// response: OK
        putrsUSART ((const far rom char *)"AT+CMEE=1\r");
       Delay10KTCYx(10);                                                   
	// sms_format
	RESET = 0;
	// SMS format type; 1=text
	// response: OK
	putrsUSART ((const far rom char *)"AT+CMGF=1\r");
       Delay10KTCYx(10);                                                   
	// sms_format
	RESET = 0;
	// Send sms to phone number
	// response: OK
	putrsUSART ((const far rom char *)"AT+CMGS=+phonenumber\r\n");
	Delay10KTCYx (10);
	// unsolecit_ind
	RESET = 0;
	// DISABLE New message unsolecited indication +CMTI
	// response: OK
	putrsUSART ((const far rom char *)"AT+CNMI=0,0,0,0,0\r"); 
	Delay10KTCYx (10);
	// storage_set
	RESET = 0;
	// AT+CPBS="SM"    set phonebook normal SIM
	putrsUSART ((const far rom char *)"AT+CPBS="SM\"\r");    
	Delay10KTCYx (50);
}

Sorry, but we cannot guess what that difficulty may be. Please explain what the problem is. Does the code fail, and if so what happens - error code, abort, crash etc?

ok, are we supposed to guess whats happening (or not happening) ?

a) ie, where does it fail ?
b) have you single-stepped through it in debug mode ?
c) is there some sort of run-time error or any other diagnostics in your system ?

most guys would love to be able to help, but we dont read minds (my own is bad enough !!)

I am able to send text message when using Hyper Terminal but currently I am making it run without Hyper Terminal. There is no compiling error, but it can't send out any text message. Hoping to know is there any logic error. Please guide me along. Thank you Smile | :)

the problem is the command set would be unknown to most of us here.

a) how do you verify that the commands you're sending programmatically to the device are being received and acted on - there doesnt seem to be any status returns/checks from [putrsUSART] - you've just said do a,b,c,d etc, and there doesnt seem to be any return saying the commands are accepted or not - if you were calling a function of your own, for example, you'd have some sort of return indicator to say the function worked or not wouldnt you ?

b) what commands do you issue in hyperterm ? list them

c) if you compared those commands from (b) to what you think your code is doing, is it doing fundamentally the same ?

thats where I'd start

I do not know about CxImage, but Gdiplus::Image can do it easily via calls to GetFrameCount() and SelectActiveFrame().

Program Which: Takes numbers from a user, and sum's them.

Hello all,

I am working on my homework for my C++ programming class and I am hitting a brick wall. Everywhere I look online does not seem to have any information in which I can apply to my program. I am supposed to use a "while" loop which I am, and thats working.

The part which is not working is the users input should add it to the previous entry, and after the user types "0" it will display the sum on the screen. I have looked at the following references to try and make sense of things:
http://www.cplusplus.com/reference/std/numeric/partial_sum/[^]
http://www.cplusplus.com/reference/std/numeric/accumulate/[^]
http://frank.mtsu.edu/~csci117/manual/lab7/lab7.html[^]
I am trying very hard to understand this, but I can not find a good online reference of the libraries. www.cplusplus.com is very good but dosent have the info I need, or more than likely I can not find it.

But here is the code to which I am trying to correct:

#include <iostream>
#include <string>

using namespace std;

int main()
{

// Global Variables
int userinput;
int sum = 0;
sum = sum + userinput;


// Start While loop
while (userinput != 0)
{
// Prompt User for input
cout << "Please enter a number. When you are finished, type 0 and press Enter." ;
cin >> ++userinput ;    

}
cout << "The sum is:" << sum << endl;
return 0;
}

Thank's to all in advance for pointing me in the correct direction so I can figure this out. I should have put this at the top: I DO NOT WANT THE ANSWER, I WOULD PREFER THE REFERENCE TO FIND MY OWN.

Outside the loop you should initialize the variable "userinput". The statement

sum = sum + userinput

before the loop should be removed. This statement should appear somewhere inside the loop. Also, for this you can use the += operator instead. The ++userinput inside the loop should just be userinput without the ++ operator.

The variables "userinput" and "sum" are not "Global Variables". They are local to the function "main".

You need to work out the details.

Thank you very much. I got it working now. I read over this while I was at dinner with the wife and figured it out at the dinner table!

here is the working code:

#include <iostream>

using namespace std;

int main()
{

// Local Variables
int userinput;
int sum = 0;

// Start While loop
while (userinput != 0)
{
// Prompt User for input
cout << "Please enter a number. When you are finished, type 0 and press Enter." ;
cin >> userinput ;  
sum = sum + userinput;  

}
cout << "The sum is:" << sum << endl;
return 0;
}

Even though this program works, you are relying on the variable userinput having an initial non-zero value. The compiler actually does not always guarantee that. To make the program robust, I suggest you take control on the values of variables and not rely on some random factors.

Good luck and happy programming!

rbwest8619-Jan-10 16:40

Now that the program adds the numbers and provides the sum at the end, I need to provide a means of displaying how many times a user input something.

The example output would be:

Sum = 134
Total numbers of inputs = 8

So I have been looking to find something on counters. I have looked at multiple web sites yet again and can not find anything. I have fixed my previous code and it is listed below. Once again, I DO NOT WANT THE ANSWER, I WANT THE REFERENCE SO I CAN LOOK IT UP MYSELF. Being pointed in the right direction helps me most.

Thank you all again.

#include <iostream>

using namespace std;

int main()
{

// Local Variables
int userinput;
int sum = 0;
int count = 0 ;

// Welcome Message
cout << "Roberts Number program v1" << endl;
cout << endl;
cout << endl;
cout << "When you are finished, enter '0'" << endl;
cout << endl;

// Start While loop
while (userinput != 0)
{      
// Prompt User for input
cout << "Input a number, then press enter. " ;
cin >> userinput ;  
sum += userinput;  

}
cout << "The sum is:" << sum << endl;
return 0;
}
