Convertendo um Vetor em Matriz

É muito comum, encontrarmos códigos onde se converte
uma matriz bidimensional em vetor unidimensional.
Más, neste código, faço o contrário, mostro como converter um
Vetor unidimensional em Matriz bidimensional.

Algumas imagens do programa em execução:

              

                              
Veja este excelente código abaixo:

#include <stdio.h>

#include <conio.h>

#define tam 100

void Moldura ( int a, int c, int b, int d, int e, int f ) {

     for ( a = e; a < c; a++ ) {

         for ( b = f; b < d; b++ ) {

              gotoxy ( b, a );

              textbackground ( WHITE );

              textcolor ( BLACK );

              printf ( " " );

         }

     }
