i use printf to display char array but it show like this :

It suppose to display :yrusianlg
anyone can teach me how to remove the unknown character..
Please Help me

This is the code

Code:

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

void shuffle(char *array, size_t n)
{
  if (n > 1) {
    size_t i;
    for (i = 0; i < n - 1; i++) {
      size_t j = i + rand() / (RAND_MAX / (n - i) + 1);
      char *t = array[j];
      array[j] = array[i];
      array[i] = t;
    }
  }
}

int main()
{
  char a[5][20] = {
    "singular","wanttome","experience","levelup","babyboy"
  };
char *word = (char*) malloc(6);
  int i,rndm,cndtn=0;
char *comp= (char*) malloc(6);
char z[100],msg[1000];
  srand((unsigned)time(NULL));
rndm = rand()%5;
  for (i = 0; i < strlen(a[0]); i++)
    z[i] = a[rndm][i];
printf("%d\n",strlen(z));
shuffle(z,strlen(z));
printf("Clues :");
//  for (i = 0; i < strlen(z); i++)
    printf("%s",z);
printf("\n");
  return 0;
}

i want to make the word shuffle....

nvm i solve already..i wrongly put array lenght..thx anyway
