C++ :: How To Assign Char Array As User Defined String Object

Apr 17, 2014

STRING s1 = “FOOBAR”

Here STRING is a user defined class. how to assign a constant char array "FOOBAR" to string object? Copy constructor need to be same class type as parameter. and overloading assignment operator also need to be same class type. I think 'friend' can let pass another type of object rather than STRING to do operation on overloaded '=' operator. How could it be done if it is possible at all?

C :: Printing A Char String From A Struct

Jan 3, 2015

I am trying to save 5 persons names to a struct, and then printing them afterwards, shortly before the program ends. I tried to print the char string out right after it has been copied over, and it showed fine, but when i try to write it out right at the end of the program (its in a separate function) the terminal just prints gibberish.

the function looks like this:

Code:
int printUser(){
printf("Following patients have been recorded in this session:
");
struct database patient1;
struct database patient2;
struct database patient3;

[Code]...

the output looks like this(as you can se in under structest, that it shows the correct string, it also uses printf):

C :: Parsing Char Array To Array Of Struct To Process Packets

May 28, 2013

I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.

decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.

whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?
Is there anything unsafe / dangrous about the way the code is now?

Code:
/* * File: main.c
* Author: david

* Created on May 23, 2013, 11:57 AM
*/

#include <stdio.h>
#include <stdlib.h>

C++ :: Using Struct / Char Array For Tic Tac Toe Game

Feb 11, 2014

I basically just want a function that tells me if 'X' or 'O' won in a tic-tac-toe game. I don't care about the visuals, I just want a function that tells me if 'X' or 'O' won. If X wins, return 0. If Y wins, return 1.

How to do the diagonals, but as far as the across and down wins, I know I have to use a nested for loop, but am a little stuck, as to exactly how to set it up.

#include <iostream>
using namespace std;
struct TTT{
char array[3][3];

C :: Assign Integer Value To Unsigned Char Array But It Is Not Storing Integer Values

Oct 25, 2013

I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet

Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}

The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.

C++ :: Char Array To String - String Becomes Garbage

Apr 20, 2013

I'm trying to "tokenize" a string using std::string functions, but I stored the text in a char array. When I try to convert it to a string, the string has the first character right but the rest is garbage.

// Get value from ListBox.
char selectedValue[256];
memset(selectedValue, NULL, 256);
SendMessage(GetDlgItem(hWnd, IDC_LB_CURRENTSCRIPT), LB_GETTEXT, selectedIndex, (LPARAM)selectedValue);
// Convert to string.

C++ :: Char Array To String

Oct 19, 2013

I have some code:

char cHomeTeamFaceOffsPercentageWon[100];
memcpy(cHomeTeamFaceOffsPercentageWon,cSqlHomeTeamFaceOffsPercentageWon,100);

After this, for example, cHomeTeamFaceOffsPercentageWon is, "29%".

Then, I use

std::string szwPercentageWon = std::string(cHomeTeamFaceOffsPercentageWon);

szwPercentageWon is then, "2". Shouldn't this convert correctly, to "29%" as well.

Or is there something I'm missing? Maybe the termination character, or something.

C++ :: Converting String To Char Array

Mar 30, 2014

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);

C/C++ :: Testing String Against Array Of Char

Apr 3, 2013

I have a text file with state names, and state abbreviations, thusly:

ALASKA
AK
ARKANSAS
AR
..and so on.

I have to load the abbreviations ONLY from the file into an array of char[ - (already done and tested).

I have to get a 2 char abbreviation as a string,then test it against the state array to make sure it is a valid abbreviation. As it stands, my test is never finding an invalid abbreviation..

Here is where I get the input:

void getState() {
char state[10];
getString("Please enter the state as a 2 char abbreviation:",state,10);
printf("State Entered:%s", state);
validState(state);

I try to fing a way to convert th string to a char using the strncopy function but still no dice..here the code i have for the createfile funciton

void CreateNew(ofstream & FileNew)//Create file
{
char filename[256];
string name;

[Code].....

How can i do this without having to ask the person to enter the file name twice..
