C++ :: Converting Char To Hex
Nov 8, 2014
Having trouble converting char to hex.
according to here [URL] ....
ô in decimal is 147 and print ô using alt 147
and here [URL] ....
ô in dec is 244 but prints ⌠ using alt 244
put on console
char c = ô;
cout << (int)c << endl;
prints -109 and print m using alt -109
I am using alt to test char output. Why I'm getting a negative value? Which of the tables are correct? I have string of char that I want to print in hex. I get a hex string but the hex value don't correspond to any of the two tables on the websites because the console converts special char to negative values.

Why is this
Code: fFile << (char) (i)p.x, (char) (i)p.y,(char) (i)p.z); not the same as this
Code: printf("%c%c%c", (i)p.x, (i)p.y, (i)p.z);

I am tying to convert an int to a char. Below is an example of the code that I have but I am getting an error('=':left operand must be l-value). I am not seeing a problem with the code.
int num = 5;
char temp[2];
char final[2];
itoa(num, temp, 10);
m_pRes->final = temp;

In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.
ReadNew function reads the file....check to see if it exist
CreateNew function creates a new file.
In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions. Here is my code.
Code:
//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;
string filelist;
void CreateNew(ofstream & FileNew);
[Code]...

Here's the code I'm working on:
string* arrayPush(string *array, char **toks){
if(array[sizeofHistory -1].empty()){
//find the next available element
for(int i=0; i < sizeofHistory; i++ ){
[Code] ....
toks is an array of pointers to strings. I need to assign a toks to array[i].

I am looking for the correct syntax to typecast a character array as an int. So I would be able to do something like this:
char ch[4];
//...Read characters from file into ch or something, etc...
int i = ( int ) &ch;
or
char ch[4];
//...Read characters from file into ch or something, etc...
int i;
strncpy ( ( char* ) &i, ch, 4 )
I want all the 4 characters ( or bytes ) of ch to be classed as an int. So we are taking the 4 bytes of the character array and placing them in 4 bytes of the integer? How would i go about this?

So I have to convert ("a499.9") into a char and a float while ignoring the a.
I have the string stored in a buffer and found how to get the char, 4. But I don't know how to get 99.9 as a float.
Here is my code so far.
#include <string>
using namespace std;
main() {
buffer = "a499.9";
[Code] ....
My output:
4
0
How to get that double out?

I am writing a program that asks the user for their gender. I know that atoi converts arrays into integers, but I need the input from the user in the form of F or M into a char, and return it to the main function to be displayed at the end of the program.
string Employee::getgender(char gen)
{
cout << "Please enter your Gender: " << endl;
//atoi function would go here, what for char?
getline(cin,gen)
return gen;
}

I am trying to convert a char buffer[1024] with raw data to int 16 buffer2[1024] which is supposed to have hex data (0x01, 0x02 kind of format).
Code:
char temp_buffer[1024];
block_size = sizeof(temp_buffer);
num_blocks = sizeof(char);
Status = mount(0, &myfsObject);
if(Status != DAVEApp_SUCCESS)
[Code] .....
I am verifying the data of resultant buffer by creating a new file and writing data to it. The result which i got is:
Code: H uy H uy H uy H uy H uy H uy H uy H uy

I've made a code to check whether or not a save file has been created correctly, but for some reason it always returns this line: readdata[qa]=='1' as true. in which qa is the counter I use in a for loop and readdata is a character array consisting of 50 characters that are either 0, 1 or 2.
this is the entire code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
[Code]....
at first is also went wrong at line 22 and also returned that as true, but then I added brackets and it worked.

I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?
joe bob joe bob
seg fault*/
/****************************************************************/
//This is here to show my struct/playerInit

I have a file which contains a year and the name of an associated file to be read. I need to extract the data in the txt file and perform some calculations.
（ year data file）
2004 2004data.txt
2005 2005data.txt
2006 2006data.txt
Here is what I do. I first declare "char yeardata" and then pass "2004data.txt" to it. Then I call yeardata in ifstream to extract the data inside the file "2004data.txt". The problem is that char yeardata is not constant so I cannot pass the file to it. It doesn't work if I change "char yeardata" to "const char yeardata".
Code:
int oldnewcomp_temp(char* lcfile) {
using namespace std;
int year;
char yeardata;
[Code] ....

From my tests I found the problem to be somewhere in the Mantissa part that converts it to binary.
bool xsDLL GetHexFromSF_IEEE754( void* to, Text from, ui08 tSize ) {
from.UpperCase();
int db = 0, dB = 0, dBEnd = tSize, dBLast = ( tSize - 1u ), dbEnd = dBEnd * 8;
ui08 *data = reinterpret_cast< ui08* >( to );
for ( ; dB >= 0; --dB )
data[ dB ] = 0u;
[Code] ....
Adjustments made, still having problems though. After finding a more useful resource [URL] ..... I got the function looking more like it should but am still having problems...

I am having problems with converting a CString to an int and than doing checks on the int to see if it is in a particualr range.Below is what I am doing.
CString numstr = "28"
int num = atoi(numstr);
BOOL valid = TRUE;
if(num < -32,768 {
valid = FALSE;
}
For some reason when running the above code the if statement is executed but it should not be becasue 28 is not less than -32,768. Why this is happening, I am not seeing the reason for this at all!! The num variable is being assigned the correct value.

I am having trouble converting strings in my application.
This is the code that is eventually getting called, the first parameter takes a LPCWSTR
Code:
hr = m_pGraph->RenderFile(m_filePath, NULL); // takes LPCWSTR This is where the trouble begins.
The compiler shows that sResult is proper but after I try to convert a std::string to a wchar it prints garbage
Code: const wchar_t* m_filePath = (wchar_t *) oDb->GetNext().c_str();
Code:
std::string CSqlLiteDatabase::GetNext() {
sqlite3_stmt *oStmt = nullptr;
std::string sql = "SELECT path || filename FROM table WHERE id = 1";
char message[255];

Code:
void convertNetPay(float netPay, char *netPayString){
int numHuns, numTens, numOnes;
char OnesTable[9][8]={"One","Two","Three","Four","Five","Six","Seven","Eight","Nine"};
char ResultString[10+1];
char TensTable[9][8] = {"Ten","Twenty","Thirty","Forty","Fifty","Sixty","Seventy","Eighty","Ninety"};
char TeensTable[9][10] {"Eleven","Twelve","Thirteen","fourteen","fifteen","Sixteen","Seventeen","Eighteen","Nineteen"};
float cents;
[Code] ....
I have to convert my netpay which is a float to a string So if I input a value of say, 356.26 it should output "the sum of three hundred fifty-six and 26/100 dollars" . My program function works for the sum of three hundred but after that it spits out garbage.

Write a program to convert the time from 24-hour notation and vice versa. Your program must be menu driven, giving the user the choice of converting the time between the two notations. Furthermore your program must contain at least the following function : a function to convert the time from 24-hour notation to 12-h notation, a function to convert the time from 12-hour notation to 24-hour notation, a function to display the choices, function(s) to get the input, and function(s) to display the results.

I have 5 apples and 9 bananas.

BASICALLY, I have to convert netpay (float to string). Theoretically if I have 666.66, my program here should output the sum of "six hundred sixty-six and 66/100 dollars".
