problem debugging this error error: incompatible types in assignment of 'uint8_t

hi can you please help me with this i try many things can any one please tell what do

#include <EEPROM.h>
#include <Keypad.h>
char targetamount[4]={0,0,0,0};
char customKey=0;
const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
//define the cymbols on the buttons of the keypads
char hexaKeys[ROWS][COLS] = {
  {'1','2','3','A'},
  {'4','5','6','B'},
  {'7','8','9','C'},
  {'*','0','#','D'}
};
byte rowPins[ROWS] = {3,4,5,6}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {7,8,9,10}; //connect to the column pinouts of the keypad

//initialize an instance of class NewKeypad
Keypad customKeypad = Keypad( makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS); 

void setup()
{
  Serial.begin(9600);void loop()
{
  
  
      targetamount=EEPROM.read(int(targetamount));
//    targetamount[c]=EEPROM.read(c);
        Serial.println(targetamount);char customKey = customKeypad.getKey();

  if ( customKey == '*')
  {
    target();
  }
//  delay(1);
}

void target()
{
  int r = 0;
  int c = 4;
  Serial.println("Enter the amount you want to saved");
  while (r<4)
  {
   char key=char(customKeypad.getKey());
    if (key)
    {
     targetamount[r] = key;
     Serial.print(key);
     EEPROM.write(c,key);
     r++;
     c++;
    } 
  }
  
  Serial.print("taget amount saved");
  customKey = 0;
}
void setup()
{
  Serial.begin(9600);void loop()
{

Look at that carefully. If you can't see a problem with it, have a look at the Blink example and see how its setup and loop functions are defined.

i try this code but it still have that error

#include <EEPROM.h>
#include <Keypad.h>
char targetamount[4]={0,0,0,0};
char customKey=0;


const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
//define the cymbols on the buttons of the keypads
char hexaKeys[ROWS][COLS] = {
  {'1','2','3','A'},
  {'4','5','6','B'},
  {'7','8','9','C'},
  {'*','0','#','D'}
};
byte rowPins[ROWS] = {3,4,5,6}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {7,8,9,10}; //connect to the column pinouts of the keypad

//initialize an instance of class NewKeypad
Keypad customKeypad = Keypad( makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS); 

void setup()
{
  Serial.begin(9600);
}
void loop()
{
  
  
//     targetamount=EEPROM.read(int(targetamount));
    targetamount=EEPROM.read(targetamount);
        Serial.println(targetamount);
 char customKey = customKeypad.getKey();

  if ( customKey == '*')
  {
    target();
  }

}

void target()
{
  int r = 0;
  int c = 4;
  Serial.println("Enter the amount you want to saved");
  while (r<4)
  {
   char key=char(customKeypad.getKey());
    if (key)
    {
     targetamount[r] = key;
     Serial.print(key);
     EEPROM.write(c,key);
     r++;
     c++;
    } 
  }
  
  Serial.print("taget amount saved");
  customKey = 0;
}

please help with this

Which line does it say the error is on?

You are not passing the correct parameters to the EEPROM read and write. Read takes an address as its argument.

    for(int i = 0; i < 4; i++)
    {
      targetamount[i] = EEPROM.read(i);
    }

Write take an address and the value to write.

  while (r<4)
  {
   char key=char(customKeypad.getKey());
    if (key)
    {
     targetamount[r] = key;
     Serial.print(key);
     EEPROM.write(r,targetamount[r]);
     r++;
     c++;
    }
  }

it works thanks a lot for all your help i really appreciate it god bless you this is now my code
