Code:
do {
printf("Edit the entry's cellphone number:");
scanf("%s", addressbook[4][num]);
length = strlen(addressbook[4][num]); //gets the length of the input (should be 10)
//checks if the input is composed of 11 elements wherein the first 2 are 0 and 9 respectively
for(i=0; i<11; i++){
[Code] ....
why do I get an error here?
Code:
if ((addressbook[4][num][0] == '0') && (addressbook[4][num][1] == '9') || (addressbook[4][num][i]>='0') && (addressbook[4][num][i]<='9') && (length=='11'))
And how do I fix this?
The error message is: comparison is always false due to limited data type

I'm trying to send out a message to all classes that are a Director. The only issue I'm running into is converting the typeof the object so the receiever parameter can hold it.
Here's my code for sending the message:
messageDispatcher.DispatchMessage(new Telegram(typeof(Director), this));
Here's where the receiver of the message gets assigned:
private IOwner receiver;
private object message;
public Telegram(object receiver, object message) {
this.receiver = receiver as IOwner;
this.message = message;
}
I tried using the Activator class to instantiate the object but was running into issues with getting it to accept the object passed. Here's what I had had:
this.receiver = (IOwner)Activator.CreateInstance((Type)receiver);
No matter what I've tried the receiver ends up being null. How could I go about assigning the type correctly to it?

Originally I had to create a simple integer palindrome program that looped while the user entered 5 digit inputs (entering -1 stopped the loop). I did this using a conversion to string, reading the length to determine if the length was valid, and then reading the string forward and backwards inside of a while loop. (snippet below)
while( digitsEntered != -1)//Allow user to quit by entering -1 to end the loop
{
ostringstream convert;//conversion stream
convert << digitsEntered;//converted text from number goes in the stream
convertedString = convert.str();//store the resulting conversion to convertedString
[Code] ....
The next stage of this program was to do the same thing with strings instead of integers. However, the option to end the loop by entering -1 is still a requirement.
I think the way to do this is to first determining whether the input is a string or an integer, and if it is a string then read it and if it's an integer determine if it's -1. However, whenever I write code to do this, it converts strings to 0 so the string is not stored and cannot be read to determine if it is a palindrome. Is there a way to determine the type of input without converting it into a different type i.e. read string and then keep string or read number and keep number?

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 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.

I'm trying to create a new data type Data declared as int. What comes up to my mind is to create a structure like
Code:
typedef struct Data {
int number;
} Data;
but when I need to use the data I need to go through the structure. Is this a good way to declare a new data type?

I'm not the best at C but I'm trying to write a C function that basically opens a text file with assembler language does a syntax error check on it and then converts the binary data into hex.
This is my code so far:
Code:

#include <string.h>
int main(void)
{
FILE*fname;
char prompt;
char filename[15];
char text[100];

I need to convert characters in a input file to numbers in output file and display both the characters and numbers in a console window.Only 7 numbers can be displayed, the rest needs to be dropped.The input file contains the following data, with one number per line:
CALL HOME
GET LOAN
Hi THERE
BYE FOR NOW
For example, once the first number in the input file has been processed, the console window should display the following: CALL HOME 225 5466.
The output file should now also contain the number:
225 5466
Currently my console is displaying the following:
Enter the input file name.
infile.txt
Enter the output file name.
outfile.txt
2554663Invalid Input
4385626Invalid Input
4Invalid Input
84373Invalid Input
293367669Invalid Input

I have a Polymorphic class and some child classes, of which I need to make multiple instances of, using a list container. I've set the key type to be a unique pointer of the polymorphic class, and the values of each element pointing to a New Child instance, like so:
std::list<std::unique_ptr<Polymorphic>> polymorphic;
polymorphic.push_back(new Child(foo, bar));
The only problem is that when I try to push_back a new element, I get a compiler error, saying "No instance of overloaded function".Should I try and create a pointer object on it's own and push back that object as an element, it will work fine:
std::unique_ptr<Polymorphic> polym(new Child(foo, bar));
std::list<std::unique_ptr<Polymorphic>> polymorphic;
polymorphic.push_back(polym);
Is there some way I can push a new Child instead of having to create a Polymorphic pointer object and pushing that?

When declare and assign an instance of a user-defined struct in a function. And the struct (theStruct) is not declared in the same header file as the function (theFunction). Like this:
files:
"A.h": declares the struct in a class (theClass)
"A.cpp": implements the struct
"B.h": declares the function
"B.cpp": implements the function, error here
I think making the instance (inst) a reference might solve this. But the instance is assigned to a return value from a function (returnFunc). Like:
void theFunction() {
...
theClass::theStruct inst = returnFunc(...);
//returnFunc() returns an instance of theStruct
//the error is at 'inst'
...
}
What do you think?

I have attached the source code I am writing. I have been getting the two following errors. I know it's something to do with the pointer casting.
udp-server.c:174:3: error: subscripted value is neither array nor pointer nor vector
udp-server.c:165:3: error: cannot convert to a pointer type
The file is attached here.

I'm trying to learn recursion, and I'm using a simple array to experiment with it, but I have a couple of annoying errors that I don't understand why they're there. Here's the code:
Code:
#include <cstdlib>
#include <iostream>
using namespace std;
int largest(const int arr[], int lowerIndex, int upperIndex) {
int max;
[code]....
Now try to print the array backwards:
//Use a recursive algorithm to find the largest element in arr:
int largest(arr[], lowerIndex, upperIndex);//error: expected an expression
return 0;

I've been writing the math functions for a 3d game and tried compiling it at about 30 functions in. I get this error related to my pointers to my structures. it affects almost everything in all my functions (as youll see by looking at how i do the math in the function below). The compiler gives me the error
"error: dereferencing pointer to incomplete type"
on all my struct Type4D pointers but referencing the values in my struct TypeMatrix4X4 using pointers seems to work fine i think (it doesn't seem to complian explicitly about it. so here is the important code...
one example function
Code:
struct Type4D *MatVecMult4X4RtoL(struct TypeMatrix4X4 *mat, struct Type4D *vec) {
struct Type4D *dest = (struct Type4D *) malloc(sizeof(struct Type4D));

I am adding int type into vector called "vi" several times like this.
std::vector<int> vi;
void addFunc(int *a, int cnt) {
vi.erase(vi.begin(), vi.end());
vi.clear();
for(int i=0; i<cnt; i++)
vi.push_back(a[i]);
}
and I call the addfunc N times every sec.
And sometimes it has runtime error on vi.push_back line.
(called stack says "_CrtIsValidHeapPointer")

I am having trouble with this program I get the error dereferencing pointer to incomplete type in the populate function I am using BloodShed's Dev C++ compiler v4.9.9.2 I copied this program out of a book because I was having a problem with a linked list in a similar program. I think there is a problem with the compiler not supporting these types of pointer's in a function.
#include <stdio.h>

char name[25];
char phone_no[15];
struct tel_typ *nextaddr;
