Checking Capital Letters against Lower Case

AnnetteB · #1 20-Mar-2005, 09:56

I have worked out how to check if a word is the same frontwards and backwards, I now need to check if they are capital letters or lower case letters - can anyone throw any light on the if statement I would need - currently for checking the letters backwards and forwards I have:

CPP / C++ / C Code:

int Front;
int Back;
bool Palindrome;

Line = ReadStringPr ("Enter string to test: ");
Front = 1;
Back = Length(Line);
Palindrome = true;

while ((Front < Back) && (Palindrome == true))
{
if (Line[Front] != Line[Back])
  Palindrome = false;
Front = Front + 1;
Back = Back - ;
}
WriteString (Line);

It is the condition that I think needs changing but I am not sure where to start?

Any help would be appreciated.

Thanks.

Annette

Look into the functions toupper() and/or tolower(). Therein lies your solution.

Also, you might want to start using code tags. You have been asked to do so 3 times so far.
