expected identifier before '1' attempting to initialize and use an array

[tmkane]

New to arduino tables and arrays. attempting to use the weekday number (0,1,2,3,4,5,6) to derive the day name (e.g., use the 0 to get the name "Sunday"). Compile result is this error message: "expected identifier before '1' "

The code:
</>
int goLed = 7;
int nogoLed = 8;
char dayname[10] = ['1' , '1' , '1' , '1' , '1' ,
'1' , '1', '1' , '1' , '1'];
int search_Argument = -1;
void setup() {
Serial.begin(9600);
pinMode(goLed, OUTPUT);
pinMode(nogoLed, OUTPUT);
digitalWrite(goLed, HIGH);
digitalWrite(nogoLed, HIGH);

dayname[10] = "111111111";
}
void loop() {
search_Argument++;
if (search_Argument > 6) {
digitalWrite(nogoLed, HIGH);
} else {
if (search_Argument == 0) { char dayname[10] = 'Sunday ';}
if (search_Argument == 1) { dayname[10] = 'Monday ';}
if (search_Argument == 2) { dayname[10] = 'Tuesday ';}
if (search_Argument == 3) { dayname[10] = 'Wednesday';}
if (search_Argument == 4) { dayname[10] = 'Thursday ';}
if (search_Argument == 5) { dayname[10] = 'Friday ';}
if (search_Argument == 6) { dayname[10] = 'Saturday ';}
}
digitalWrite(goLed, HIGH);
Serial.println(dayname);
}

char dayname[10] = ['1' , '1' , '1' , '1' , '1' ,
                    '1' , '1', '1' , '1' , '1'];

The list of values goes in { }, not [ ]

  dayname[10] = "111111111";

This line of code attempts to set element 10 of the dayname array to a string. Eelemt 10 does not exist, nor can you set a single char element to a string

      char dayname[10] = 'Sunday   ';

This is an an attempt to set element 10 to a multi character char but a char can only have one character so 2 errors

This may give you some inspiration

int goLed = 7;
int nogoLed = 8;
char * dayNames[] = {"Sunday", "Monday", "Tuesday"};  //add as many more as you need


void setup()
{
  Serial.begin(115200);
  for (int dayNum = 0; dayNum < 3; dayNum++)
  {
    Serial.println(dayNames[dayNum]);
    if (strcmp(dayNames[dayNum], "Monday") == 0)
    {
      Serial.println("It's Tuesday today");
    }
  }
}

void loop()
{
}

An extended version

int goLed = 7;
int nogoLed = 8;
char * dayNames[] = {"Sunday", "Monday", "Tuesday"};  //add as many more as you need
const byte NUMBER_OF_DAYS = sizeof(dayNames) / sizeof(dayNames[0]);

void setup()
{
  Serial.begin(115200);
  show();
  show();
}

void loop()
{
}

void show()
{
  for (int dayNum = 0; dayNum < NUMBER_OF_DAYS; dayNum++)
  {
    Serial.print(dayNum);
    Serial.print(" ");
    Serial.println(dayNames[dayNum]);
    if (strcmp(dayNames[dayNum], "Monday") == 0)
    {
      Serial.println("Tuesday has been renamed to Bobday");
      dayNames[dayNum] = "Bobday";
    }
  }
  Serial.println();
}

It can always be useful to share the solution so other people that encounter the same problem can learn from it.

I can see that you made an attempt to use code tags but it did not work out. One way to do it

Type
** **[code]** **

Paste your code after that
Type
** **[/code]** **
after the pasted code

Alternative if you're a mouse junk

Click the </> icon in the left top ( not: type </> ); it will put the above code tags in the post for you and next you can paste your code in between the tags.
