C++ запрещает преобразование строковой константы в char [закрыто] ⇐ C++

Я настроил vscode для проекта igraphics в соответствии с инструкциями https://drive.google.com/file/d/1YLd8IN ... sp=sharing в этом PDF-файле. Но мой код не работает. Показаны эти ошибки:
1 и 2
какое может быть решение?
Вот код

Код: Выделить всё

# include "iGraphics.h"

int x = 300, y = 300, r = 20;
/*
function iDraw() is called again and again by the system.

*/

void iDraw() {
//place your drawing codes here
iClear();
iSetColor(20, 200, 200);
iFilledCircle(x, y, r);
//iFilledRectangle(10, 30, 20, 20);
iSetColor(20, 200, 0);
iText(40, 40, "Hi, I am iGraphics");
}

/*

void iMouseMove(int mx, int my) {

//place your codes here
}

/*

x += 10;
y += 10;

if (button == GLUT_RIGHT_BUTTON && state == GLUT_DOWN) {

x -= 10;
y -= 10;

}

//place your codes for other keys here
}

int main() {
//place your own initialization codes here.
iInitialize(400, 400, "demo");
return 0;
}

Я настраиваю рабочее пространство перед изучением языка. Подобных вопросов много, но я не понимаю ответов, так как не знаю языка.
