Hola colegas, requiero de un parde manitos, la una es para saber como
ejecuto
desde Turbo c++ para windows un ejecutable como proceso hijo, por ejemplo
ejecutar un programa como winword.exe y cuado se cierre winword.exe se
ejecute el resto de lineas de c++, y la otra es para saber el comando con
el
que copia un archivo.

Gracias por su ayuda.

Hola Garzon

Para copiar un archivo usa la función
CopyFile de SDK
tambien puedes hacerte una lees el archivo y lo guardas

algo parecido a las siguientes funciones

una cosa importante las siguientes funciones son solo a titulo de ejemplo,
que solo funcionan con formato texto (*.txt) y no con archivos binarios.

un saludo
