there is a minor problem with hangman; whenever a word is randomly chosen, if it is less then six letters, the program attaches junk to the end until it equals six characters (junk is random characters ' X . )what shall i do?




//program Hangman

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

//------------------definition of class hangman----------------------

char* getWord(int&);

//creates temporary holder for unguessed characters

void checkGuess(char&, int&);
//checks user guess against inputted word

char* SecWord;
char* temp;
