How to initialize a char[50] to empty at struct constructor

[tonnot]

struct my_struct {
int var1;
...
char[50] txt1;
my_struct(){txt1=""}
};

I'm unable to initialize txt1 to empty value....
Heeeelp

I need this, because when write to file I discover that I have uninitialized strange data.

Thanks

memset( txt1, 0, sizeof( txt1 ) );

char txt1[50] = {};

err whoops.. for a class,

struct my_struct {
int var1;
...
char txt1[50];
my_struct() : txt1() {} // use an initializer list
};

Nothing .....
can't compile no combination I write.....

struct my_struct {
 int var1;
 char txt[50];
 my_struct(){
 var1=0; 
 txt = ??????????  
 };
};

I'd want to initializa txt to zero characters (empty), or 50 blank spaces.
I remain needing help ......

What about this?

struct my_struct {
   int var1;
   char txt[50];
   my_struct(){
      var1=0; 
      memset( txt, 0, sizeof(txt) );
   };
};

memset is ok .
