wprintf and printf

[sabya123]

I have got a problem using printf and wprintf.
Can I use them simultaneously in a single program?
My problem is that, If I am using both of them in a program only the first one is being taken.
Suppose the first output statement is:-
printf("%s", "Hello world");

then throug out the program only 'printf's are being printed. and the 'wprintf's are not printing anything.

And the reverse is also true, i,e, if the first output statement is 'wprintf', only wprintf statements are printing. And 'printf's are not printing anything.

I'm writng a sample code for reference:-
I am using compiler g++.
--------------------------------
#include <iostream>
#include<wchar.h>
using namespace std;
int main()
{
printf("\nHello world, within printf\n");
wprintf(L"\nWithin wprintf, This is not printing.\n");
printf("\nHow are you?, Within printf\n");

}

-----------------------------
Any help?

Thanks in advance.
