When i am entering single character instead of 'miz' then it is working great. But when i am using multi character like 'miz' it is showing error output. i did this program with c++ it is working but not working in c.When i am running this program it is showing {warning] multi character constant.
Code:
#include<stdio.h>
#include<string.h>
main()
{
char a;
printf("Please Enter your First Name: ");
scanf("%s",&a);

I can't find why it won't output the correct info for the array. I've looked until I am ready to throw the computer out the door. I'm at my wits end trying to get this to work right. I finally got it to quit killing the compiler, but it's doing this. The problem is in the insertBefore or insertAfter function calls and I don't think that my copy constructor is right.
#include <iostream>
#include <cstdlib>
#include <fstream>
#include <iomanip>

I am trying to create a few subclasses which all use the base class constructor, according to my book this is all fine and dandy by using the "using Baseclass::Baseclass", this doesnt work for me.
class Monster {
public:
Monster(char[], char[], char[], int); //The constructor, and its implemented.
etc..
};
[Code] ....
Yet, i recieve this error:
error LNK2019: unresolved external symbol "public: __thiscall Human::Human(char * const,char * const,char * const,int)"
Why is this? Does doing it this way create const pointers somehow? The constructor works fine with Monster, i am using the same calls, just changed to create Human instead of Monster. All files are included where they should, monster and human are declared in the same header.
Is it possible to alter an error message for a particular line if you think it might fail compilation? GNU specific stuff is okay. The reason I want to do it is because I have this code.
Code:
template <size_t S>
struct assertion{}
int main(){
{
volatile assertion<sizeof(config::input)> asrt = assertion<sizeof(config::output)>();
}
}
If the arrays config::input and config:utput are different sizes, I want it to be clear that that's what needs to be fixed. Is there an __attribute somewhere that will allow me to do that?

i am writing this bank accounts program using structures. i haven't implemented the function before that i want to check if the data is being read and printed. When i build and run the program in visual studio it gives me the following error. "No constructor could take the source type, or constructor overload resolution was ambiguous". Now whats wrong in this program?

VS 2012 / Windows 7 64 bit
class
class myclass {
public:
myclass(){/*stuff here*/}
myclass(int* p) {MyPointer = p; myclass()}
[Code] ....
it works until the myclass(int* p) calls myclass()
then the MyPointer will become CCCCCCCC (NULL value)!
is there a way to stop the second constructor from resetting the pointer value to null?

SLD_ttf lib and I have been following the Lazy Foo' tuts on it but the text is not appearing. I have found out that it is not loading the font as I have added in the code saying if it has failed.
Code:

if( font == NULL )
{
return false;
}
i have saved this font in the project (project name/project name/lazy.ttf).

I've run across this issue before, but for the like of me, I can't figure out what keeps causing it. The problem compiles and runs as expected; however in the salaried object (Employee #1 in main.cpp) the console displays the number of vacation days as -858993460 instead of the value entered.
The parent Employee class is abstract with calculatePay() and displayEmployee() being pure virtualls and with a Benefits, Salaried, and Hourly class derived from it.
The Salaried displayEmployee() and the portion of the Main.cpp that contains the salaried object follows. What causing this?
Salaried displayEmployee()
Code:
void Salaried::displayEmployee()
{
cout << endl;
cout << "Employee Information" << endl;
cout << "----------------------------------" << endl;
cout << "Employee Name: " << setw(7) << FirstName << " " << LastName << endl;
cout << "Gender: " << setw(12) << Gender << endl;

I'm receiving an error that an array has not been initialized but I'm not quite sure why. Also, I realize a list may be better in this scenario but I would still like to know what I'm doing wrong.

Same solution that I was having compiler errors on yesterday. We're working with inheritance and the program is supposed to be to create and display information for default Employee objects, Hourly Employee objects and Salaried Employee objects. Everything compiles as is, but I'm running into two issues that I can't figure out.
1) In both the hourly and salaried objects, the wage, hours, and management level attributes all displaying their default values. I'm almost positive that this has something to do with the str to int and str to double conversions that I'm using (currently have atoi and atof in the file, but I've also tried stringstream, but still had to same problem). Any thoughts as to what I'm missing?
2) the assignment calls for the Benefit benefit member in Employee.h to be protected. However this makes the member unaccessible when I try to use it in the EmployeeMain.cpp in order to set the input for the Benefit class members. I had to make the Benefit benefit member public again to get it to compile. How would I set the input for the Benefit class members while the Benefit benefit member is protected?
Solution files follow:
EmployeeMain.cpp
Code:
#include "Hourly.h"
#include "Salaried.h"
void DisplayApplicationInformation();
void DisplayDivider(string);
string GetInput(string);

I'm writing a program that shows check fees for different amounts of checks. My other fees are showing up right but the .10 cents is not. It's showing up as .08 cents per check when I run the program.
Oh yeah the + 10 is for a $10 fee
Code:
else if (checks < 20 || checks >= 0) {
fee = .10 * checks + 10;
cout<< "Bank service charge for the month is $ " << setprecision(4) << endl;
}
So I have a small game I'm making using OOP principles, I know it's a little bit of overkill but it's just for educational purposes. I have a sprite character that can be moved around with no problems, but I made a sword for him as a separate sprite that doesn't follow him. The sword sprite is supposed to cover his arm and his body as it swings, but it just stays in the upper left corner.
I messed around with the initialization of the sword in the main.cpp and I changed in sword.cpp and sword.h and it still is showing up in the same place. I even looked at the GetX() and GetY() statements I made and they seemed to work fine and when I debugged it, the variable values showed up correctly, but the sword doesn't move.
