I've been working on a project with my arduino that display a knock knock joke on an LCD but I ran in to a problem while coding.
This is what I have so far
#include<LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
int buttonPin = 13;
int menu = 0;
int joke(int line1, int line2){
lcd.setCursor(0, 0);
lcd.print(line1);
lcd.setCursor(0, 1);
lcd.print(line2);
lcd.setCursor(0, 0);
}
void setup(){
pinMode(buttonPin, INPUT);
lcd.begin(16,2);
}
void loop() {
lcd.setCursor(15, 0);
lcd.print(menu);
int buttonValue = digitalRead(buttonPin);
if(buttonValue = HIGH){
menu = menu + 1;
}
if(menu == 0){
joke("Knock!", "Knock!");
}
But when I run it I get the errors
LCD_HelloWorld.ino: In function ‘void loop()’:
LCD_HelloWorld.ino:28:28: error: invalid conversion from ‘const char*’ to 'int’ [-fpermissive]
LCD_HelloWorld.ino:7:5: error: initializing argument 1 of ‘int joke(int, int)’ [-fpermissive]
LCD_HelloWorld.ino:28:28: error: invalid conversion from ‘const char*’ to ‘int’ [-fpermissive]
LCD_HelloWorld.ino:7:5: error: initializing argument 2 of ‘int joke(int, int)’ [-fpermissive]
After scouring the internet I've found nothing, so does any body have a solution? BTW: I'm new to arduino and C/C++

change
int joke(int line1, int line2)
to
int joke(const char * line1, const char * line2)
