Thread: building a password

Hi.

Could someone please explain to me why this is wrong and how to fix it. thank you.

Code:

int main()
{
   char password [20];
   int x=0;
   printf("please enter a password with one number and one uppercase letter: ");
   scanf("%c", &password);
    scanf("%d", &x);
    if (x<0)
    {
        printf("please enter at least one number \n");




    }
    if (isupper != (password))
    {
        printf("please enter at least one upper case");
    }


}

If i understand correctly. You can probably read the value entered by the user into string. Then you can start processing from the beginning of the string. You also need to tell the user correct format of password.
