how to find address of string in binary in gdb?

So here is the source code of the binary:

#include <stdio.h>

int main(){
  printf("Hello World\n");
  return 0;
}

and below is the compilation of this source code:

@CTOS:/tmp/mytemp$ gcc helloWorld.c -o helloWorld

Now when I disassemble my binary in gdb as below:

Reading symbols from helloWorld...
(No debugging symbols found in helloWorld)
(gdb) disassemble main
Dump of assembler code for function main:
   0x0000000000001149 <+0>:     endbr64 
   0x000000000000114d <+4>:     push   %rbp
   0x000000000000114e <+5>:     mov    %rsp,%rbp
   0x0000000000001151 <+8>:     lea    0xeac(%rip),%rax     
   0x0000000000001158 <+15>:    mov    %rax,%rdi
   0x000000000000115b <+18>:    call   0x1050 <puts@plt>
   0x0000000000001160 <+23>:    mov    $0x0,%eax
   0x0000000000001165 <+28>:    pop    %rbp
   0x0000000000001166 <+29>:    ret    
End of assembler dump.

(gdb) p (char*)0xeac
$1 = 0xeac <error: Cannot access memory at address 0xeac>

Now I want to know the address of the "Hello World" string which is passed inside puts function call, I want to display the address in gdb by gdb command. How do I do that?

Solution

step (s) into the print yield this output:

__GI__IO_puts (str=0x555555556004 "Hello World") at ioputs.c:35

Another option is to look search for string in text segment of the process. You do that first by looking at process mappings then use find for the string.

(gdb) info proc mappings
process 212970
