Getting error while declaring a char variable in arduino-IDE

I am trying to program ESP8266-Wifi module through Arduino-IDE. I am having an error in the following code snippet, any help would be much appreciated.

// Import required libraries
#include <ESP8266WiFi.h>
// WiFi parameters
constchar* ssid = "your_wifi_name";
constchar* password = "your_wifi_password";

void setup(void)
{
 // Start Serial
 Serial.begin(115200);
 // Connect to WiFi
 WiFi.begin(ssid, password);

 while (WiFi.status() != WL_CONNECTED) {
 delay(500);
 Serial.print(".");
 }

 Serial.println("");
 Serial.println("WiFi connected");
 // Print the IP address
 Serial.println(WiFi.localIP());
}

void loop() {
}

below you'd find the error which is given by my arduino IDE version 1.8.18:
