glVertexPointer(3,GL_FLOAT,24,00000000)
I know the last arguement points to the first coordinate of the 1st vertex
But how will i be able to obtain that coordinate?
Thank you and please respond.

Sounds like you want to know the vertex after transformation. You can read the theory here
http://www.opengl.org/wiki/Vertex_Transformation
and the function you can use us gluProject.

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
