What am I doing wrong with this char?

I don't know what am I doing wrong to that char since it's just a test program. I called srand() correctly just once, yet I don't know what is wrong with randchar, it still prints the same character.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main(void)
{
     char randchar = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" [rand() % 26];
     int ve;
     srand(time(NULL));

     for(ve = 0; ve < 10; ++ve)
     {
          putchar(randchar);
     }

     return 0;
}
