Hi,

Im quite new to C++ and am trying to learn most of the commands.
So i wanted to make a Programm that has a normal mode and a non normal mode, kindof.
And i wanted to make a question, which the user has to answer to start normal or unnormal mode.
I think this code should show my idea.

The if command never Reacts to a j.
Why is that??

Code:

  char jon;

We are writing a code for I2C interface,
where we are reading a 16 bit Hex number as two 8 bit Hex MSB and LSB, and we are returning these values as "Unsigned Char".

we want to concatenate these MSB and LSB "char" values, and finally we need one "Integer" value for our further processing.

for example: the following 2 methods are returning one "Unsigned Char" value, each...

Hello.
I use BlueJ 3.0.1
I am writing a program to dictionarize words(arrange words in dictionary order).

But the 'char' type isn't working properly.

Code:

char ch1 = 'qwerty' ;//shows error
char ch2 = 'qwedrt';
if(ch1>ch2)
{
System.out.println(ch2);
System.out.println(ch1);
}
else
{
System.out.println(ch1);
System.out.println(ch2);

Hey there I have a data structure with a set size of 40 I want to marshall the data from an object into an array of characters for simplistic transmission of data. I am aware of serialization but only familiar with it in higher languages, I am stuck using c.

My question is this. How do I point to an individual character value of the unmarshalled object in order to marshall it into a character array I can throw down the socket pipe?...

I have a function that returns an integer, between 1 and 255. Is there a way to turn this int into a character I can strcmp() to an existing string.

Basically, I need to create a string of letters (all ASCII values) from a PRNG. I've got everything working minus the int to char part. There's no Chr() function like in PHP.

I recently converted my application into C# as VS2008 does not support new Data Sources (?!), but now I am stuck on one command from the old DLL.

Here is the old function declaration and command that worked in C++:

Code:

 typedef short(*pfunc2)(short address, LPSTR cmd, short irqnum);
 pfunc2 pfSendAT6400Block	=	(pfunc2)GetProcAddress(hndl, "SendAT6400Block");

char *testCommands[258] = {"A100:V50:D254000:GO1:"};

I'm making a program that is supposed to change certain input and leave most unchanged, and then spit out an output. I decided I should store the output in a single char[] before writing it out, so I could build on the program later, however doing this I ran into an issue. Anyway, the main.c is attached as a txt.

Changing all the stuff seems to work fine, it's just that adding the normal characters isn't working. I get warnings, and...

I am trying use the following code to convert a char to an int but it's not working.
For some reason PosToMoveTo contains 4000 instead of 4. I am not sure why...

main()
{
int i;
int dis;
char * Distance;
char N0, N1, N2, N3, N4;
int PosToMoveTo;
ReceivedStr = "P0004";

N0 = ReceivedStr[0];
N1 = ReceivedStr[1];...

I have to create a program that has validation in it, The programme asks the user for the weight of a package, and sets the cost appropriately, I have a do in place do that if the user types in a minus number it gives them an error.

do{
clrscr();
cout<<"\n Enter the weight of the package to be delivered ";
cin>>weight;
if(weight<0)
{
cout<<"\n Error! ENTER...
