    First of all, you should NEVER EVER use gets()
    SourceForge.net: Gets - cpwiki

    Second, if you're using TCHAR and a Microsoft platform, you should read this
    Using Generic-Text Mappings (CRT)

    So for example, _fgetts maps to fgets() when TCHAR is a char, and fgetws() when TCHAR is a wide character.
    Code:
    TCHAR str[45];
    _fgetts( str, sizeof(str), stdin );
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Almost:
    _fgetts( str, sizeof(str) / sizeof(*str), stdin );

    The buffer size is in characters, not bytes.

    Look for the TCHAR version of strcat. It's probably strcat with an extra t somewhere, and maybe an underscore at the front.

    Be aware: you will have to make sure you have enough room in your result string for the entire result. As you have it now, neither str1 nor str2 will be long enough.

    here to add two TCHAR strings Im using _tcscat()
    but there is a problem when I take one string Input at run time..
    here is the code
    Code:
    void main()
    { TCHAR A[50];
    TCHAR B[20]=_T("World");
    _fgetts( A, sizeof(A), stdin);   //Here I give input "Hello" in the String A.
    _tcscat(A,B);
    _putts(A);
    getch();
    }
    here the output is: Hello
    World

    and want it as: Hello World

    HELLPPPP..

    Then strip off the newline before adding world to the end.
