error loading an array of strings

Question

I'm trying to have a user enter a series of strings. This is my code.

this is my error message - cannot convert 'String' to 'char*' in assignment

char* titles[] = {"entry one", "entry two", "entry three", "entry four", "entry five"};


void setup() {
 Serial.begin(9600);
 Serial.println("Storing numbers in an array");
}

void loop()

{

for (int x =0; x < 5; x++)
{
  if (Serial.available() > 0)

  {
   Serial.println("Enter a word... ");
   titles[x] = Serial.readString();

    Serial.println(" ");
    Serial.println(chartitles[x]);

   }
  } 
 }

Answer 1

So, you are confusing the object String of Arduino with a string of C (char array), to solve your problem, I've changed your code in two parts:

String titles[] = {"entry one", "entry two", "entry three", "entry four", "entry five"};

void setup(){
  Serial.begin(9600);
  Serial.println("Storing numbers in an array");
}

void loop(){
  for (int x = 0; x < 5; x++){
    if (Serial.available() > 0){
      Serial.println("Enter a word... ");
      titles[x] = Serial.readString();
      Serial.println(" ");
      Serial.println(titles[x]);
    }
  }
}

So, in order to use Seria.readString(), you have to use String objects to receive the data from Serial port:

String titles[]

Instead of:

char* titles[]

The second change is related to Serial.println(chartitles[x]), I didn't understand what you mean with this code, so I changed in order to print the String that was read.
