How to Store 2 analogRead values and read using EEPROM for Arduino unoUno?

Trying to write 2 values coming from analogread(A0)analogread(A0) and analogread(A1)analogread(A1) by EEPROM.writeEEPROM.write and retriveretrieve the values by EEPROM.readEEPROM.read. I tried the following sketch for each write and read. However, could not get the values. Any help please.

For writing to EEPROM:

#include <EEPROMex.h>
int addr = 0;
int array[] = {0, 0};
char a;
void setup() {
}
void loop() {
    array[0] = analogRead(0) / 4;
    array[1] = analogRead(1) / 4;
    EEPROM.write(addr, a);
    addr = addr + 1;

    if (addr == 512) {
        addr = 0;
    }

    delay(100);
}

For reading from EEPROM is:

#include <EEPROM.h>
int address = 0;
int value[2];
void setup() {
    Serial.begin(9600);

    while (!Serial) {
        ;
    }
}
void loop() {
    value = EEPROM.read(address);
    Serial.print(address);
    Serial.print("\t");
    Serial.print(value[0]);
    Serial.print("\t");
    Serial.print(value[1]);
    Serial.println();
    address = address + 1;

    if (address == 512) {
        address == 0;
    }

    delay(500);
}

Code snippets were labelled incorrectly (the 'read' snippet was actually the writing part)
