Hola a todos estoy trabajando en un tp bajo linux y son mis primeros pasos bajo
este sistema, el problema me surge al ejecutar un programa que me dice que
provoca una violación de memoria, utilice el valgrind para ver si podía
entender que es lo que sucedió pero no consigo entender la salida del programa,
parte de cual copio a continuación:
Salida de valgrind --tool=memcheck tp1
