Basic idea on printf function

This program is depentd  on printf function. in  most of c programs we use Printf function  .  Now I want to give you a basic idea on printf function. 

#include <stdio.h>

      puts("Enter your last name > ");
      gets(lastName);
     
      char userName[12];
      puts("Choose your user name > ");
      gets(userName);
     
      int password[10];
      puts("Creat a password > ");
      gets(password);
