Question

I’m trying to print an array of characters in C but i can’t print everything.
I want to print :
b1
b2
My code:

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

int main() {
  char def[3][10];     //define a multidimensional array of characters 
  strcpy(def[0],"b1"); //insert "b1" at first line
  strcpy(def[1],"b2"); //insert "b2" at first line
  printf("%s",def);    //print everything?
}

The above code prints just b1. I already tried :

printf("%s",def[0]);
printf("%s",def[1]);

But i have error “invalid use of array with unspecified bounds”

Answer 1

printf("%s", def);

%s conversion specification expects a string. def is an array of strings and not a string.

To print the first string do this:

printf("%s", def[0]);

if you want to print the second string then do this:

printf("%s", def[1]);

and if you want to print both strings:

printf("%s%s", def[0], def[1]);

To print all strings in your array:

for (i = 0; i < sizeof def / sizeof *def; i++)
{
    printf("%s", def[i]); 
}
