Programa y aceleracion

Hola buenas, tengo un problema estoy ocupando un programa llamado LCC-win32, pero he tenido muchos problemas para compilar y crear nuevos proyectos, algun programa mas facil de utilizar, ademas necesito en el programa insertar un cronometro y un aformula que calcule la aceleracion de un objeto que pasa por dos sensores, tengo la velocidad inicial, la ditancia, esto lo pienso hacer con un while, dejo pregrama,,...gracias ;-)
