Tips for project

I have to do this project in my C++ class but I am not certain how, any tips or hints would be appreciated.
The problem reads as follows...
"declare a character array named Alpha and initialize it to ABCDE...
In your program, include a loop that replaces one character at a time with the lowercase letters a-z. Print the character array to the screen during each iteration of the loop.

To initilize an array to ABCDE, do this:

char Alpha[] = {"ABCDE"};

then just loop though the array and assign all the elements with their equvilant lowercase values. I don't want to tell you too much, because that would diminish the point of the exercise, but try:
(int)Alpha[i] -= ('A' - 'a');

Good luck.

The easiest way to change the captialisation on a letter would be:

Alpha[i] ^= 0x20;

It works most of the time, but it doesn't go too well when a something other than a letter is encountered.

Well the entire program is given below.. This is how you do it. Run this program and you will get the result you want.. This program was done using turbo c++

# include <iostream.h>
# include <conio.h>

main()
{
clrscr();
int i;
char alpha[26]="ABCDEFGHIJKLMNOPQRSTUVWXYZ";
for(i=0;i<26;i++)
{
alpha[i]=alpha[i]+32;
cout<<alpha[i];
}


}

stupid question but ill ask it
i saw several times the clrscr() around

but when i try to compile something in microsoft c++ enterprise edition it gives me an error always undeclared idientifier??

clrscr() is only good for Windows based systems since it is a thin encapsulation of a Windows function. But anyway, #include <conio.c>
