I've tried to play with little details, and yet, doesn't seem to work properly. And I don't know why!

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

int main()
{
    char adminName[20];
    char userName[20];
    adminName[20]= "Admin";

    printf("Please, enter your name:");
    scanf("%s", userName);

    if(userName == adminName) {
        printf("Welcome, Admin! \n");
    }

    printf("Wrong log-in details, %s. \n", userName);
    return 0;
}

  • Change this `if(userName == adminName)` **->** `if(strcmp(userName,adminName)==0)`. – ameyCU Nov 11 '15 at 06:01
  • Because you are comparing strings. That's not how comparing strings works. That's not how any of it works! – NSNoob Nov 11 '15 at 06:03

In your question there are a lot of mistake. First of all 

adminName[20] ="admin";

will throw an warning, and your admin array is not made "admin", while the 20th element which doesn't even exists, as u have max of adminName[19].

You can't directly copy a string to another array, use this for string copy

strcpy();

And for comparison, use

strcmp();

And better learn string.h header files. Those two are present in string.h header file

Please try this, it works as you wanted, read notes in the code, it is normal to make a few mistakes while learning.

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

int main(  )
{
  char adminName[20];
  char userName[20];

  strcpy( adminName, "Admin" ); // use strcpy

  printf( "Please, enter your name:" );
  scanf( "%s", userName );

  if ( !strcmp( userName, adminName ) ) // use strcmp
  {
    printf( "Welcome, Admin! \n" );
  }
  else              // use else
    printf( "Wrong log-in details, %s. \n", userName );

  return 0;
}
