Yep, they are really well written.
You're most welcome Stuart.

Only in the case when UNICODE is not defined. The suggestion from Superman is better, it is independant of whether UNICODE is defined or not.

If you're entering values in a edit box, for instance, then you don't need such conversion at all: you may directly map a integer variable to the edit box content.

i use this but i can't set a int variable because of adding number with button like windows calculator. see it.
thanks for ur attention.

If you're using buttons to enter numbers, then why do you need a CString variable?

OK, I admit it. We have been looking for the calculator code for years. Busted...

I suspect it was your search criteria that was. Did you consider atoi() ? See here.

Could someone pls explain the below question?
Q1 : In line1 the second parameter is referece to integer constant.
If so how is the value in 'x' changed to 4
Question:
#include<iostream>
#include<conio.h>
using namespace std;
int mani(int (&arr)[10], const int& x)
{
for (int i = 0; i < 1; ++i)
arr[i] = arr[i] + x;
return x;
}
int main(){
int arr[10] = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11};
cout<<mani(arr, arr[0]);
}

Since the variable x is a reference to the a[0] , when ever you use x, keep in mind that you are actually using a[0] itself. And in the for loop, when the value of i = 0 , you chnages the value of a[0] and so the x will also points to new value.
Defining the x as constant only prevents directly chaging the value of x, using the x variable itself. something like x = a[2]; will be shown as error.

Well, "x" an indeed an "integer constant" from the our point of view: by taking a constant reference, we obligate ourselves not to change the value of "x", we can only read it. However, it does not mean that the value of x has to be constant, it's just that _we_ can't modify the respective memory area through this variable named "x". If it's not a constant actually, then anyone else, or even us, through an other alias can modify the memory area (in this example through the non-const reference to the array), the modified value of course reflecting also when accessing the value of x.
So, in this example, "x" is just an alias to the first element of the "arr" array marked const (=you can't modify the value through me), but since the function takes the array by reference (thereby obtaining an alias for the original "arr" array) and changes its first element (remember, the array is a non-const reference, it can be changed), it actually changes the first element of the original, global "arr" array, but "x" is still just an alias for this, thereby its value must be 2 + 2 = 4.
