C++ If Else statement Problems - c++

Question

My code contains an If Else statement. I want it to validate a string that a user inputs puts into the script on two things:
The length of the string has to be more than 0
The string has to consist of alphabet characters
Below is my code, I think the error is to do with the length of the string piece of code.
Before Edit:
cout << "Your word: " << szOriginal << "\n";
if szOriginal.length() > 0 and (isalpha(szOriginal))
{
szWord = szOriginal.tolower();
cout << szWord << "\n";
}
else
{
cout << "Please enter a valid word." << endl;
}
Sorry guys, the error produced by Dev-C++ is
expected '(' before "szOriginal"

After Edit with variable declaration and such:
#include <cstdio>
#include <cstdlib>
#include <string>
#include <iostream>
using namespace std;
int main(int nNumberofArgs, char* pszArgs[])
{
string original;
cout << "Welcome to the English to Pig Latin translator!\n";
cout << "Type a word you wish to translate:\n";
cin >> original;
cout << "Your word: " << original << "\n";
if (original.length() > 0 && (isalpha(original)) )
{
word = original.tolower();
cout << Word << "\n";
}
else
{
cout << "Please enter a valid word." << endl;
}
system("PAUSE");
return 0;
}
So sorry for this bad post!

Answer 1

if ( [...] ) - you're missing the brackets.
Also, it's && instead of and.

Answer 2

I think you are coming from a python background
cout << "Your word: " << szOriginal << "\n";
if (szOriginal.length() > 0 && (isalpha(szOriginal)) )
{
szWord = szOriginal.tolower();
cout << szWord << "\n";
}
else
{
cout << "Please enter a valid word." << endl;
}
you need ( ) around the if condition, and use && for logical and
EDIT
you are using szOriginal as a char when you say isalpha(szOriginal)
and as an object when you say szWord = szOriginal.tolower();
so you need to look into that also
