edit: I discovered I had to use glPushMatrix() and glPopMatrix()

Good morning. I wrote the program below but I can't make it show the lines of x,y only translate the object. What could I have done wrong ?

Code :
 
  #include "GL/freeglut.h"
  #include "GL/gl.h"
 
  void draw(void) 
  { 
 
	glClear(GL_COLOR_BUFFER_BIT);
 
        // lines 
	glBegin(GL_LINES);
	glColor3f(1.0f, 1.0f, 1.0f);
	glVertex2f(-1.0f, 0.0f); 
	glVertex2f(1.0f, 0.0f); 
	glVertex2f(0.0f, 1.0f);
	glVertex2f(0.0f, -1.0f); 
	glEnd();
 
 
	glPushMatrix();
        glTranslatef(1.0f, -1.0f, 0.0f);
 
        // rectangle
        glBegin(GL_QUADS);
	glColor3f(1.0f, 1.0f, 1.0f);
	glVertex2f(-0.25f, 0.25f);
	glVertex2f(-0.75f, 0.25f);
	glVertex2f(-0.75f, 0.75f);
	glVertex2f(-0.25f, 0.75f);
	glEnd();
 
        glPopMatrix();
	glFlush();  
} 	   	  
 
  void init(void) 
  { 
	glClearColor(0.0f, 0.0f, 0.0f, 1.0f);  
  } 	   	  
 
  int main(int argc, char** argv) 
  { 
	 glutInit(&argc, argv);
	 glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
	 glutCreateWindow("Rectangle Translation");
	 glutDisplayFunc(draw);  
	 init();
	 glutMainLoop();
  }
