Hi,
Is there someone out there who can help. I've written some simple functions, on the same page as the main code:
bool IsAVowel (char ch)
{
if(ch=='a')|| (ch=='e') || (ch=='i') || (ch=='o') || (ch==''u)
{
return true;
}
return false;
}The compiler message gives 'linker error'
Why won't the main program use these. Sorry if this is a bit basic, but could really use some help with this.

What's the error msg?

i am not sure ,
but why can not the if statement be like this :
if(ch=='a'|| ch=='e' || ch=='i' || ch=='o' || ch==''u)try to run it and see.
Did you define the function like this: bool IsAVowel (char) before calling main? Not doing this will result in a linker error (something like: could not find function definition). Your program should look something like this:
#include <blabla>
bool IsAVowel (char);
int main(void)
{
-code-
}
bool IsAVowel (char ch)
{
if (ch=='a')|| (ch=='e') || (ch=='i') || (ch=='o') || (ch==''u)
{
return true;
}
return false;

I think you either didn't post the real code, or your compiler is giving bogus error messages. Before going any further, I would fix the syntax error in this line:
if (ch=='a')|| (ch=='e') || (ch=='i') || (ch=='o') || (ch==''u)If (ch==''u) compiles at all, it most certainly won't do what you intend.
