pourquoi le code fonctione dans code block et non pas sur visuel c++

salut.
j'ai un problème avec IDE visuel studio c++ express tel que:
j’écris un code dans IDE codeblocks et le code fonctionne très bien;
mais lorsque j'ouvre un nouveau projet dans visuel c++ et je copie le code dans un nouveau fichier;le compilateur affiche beaucoup erreurs;

========== Génération*: 0 a réussi, 1 a échoué, 0 mis à jour, 0 a été ignoré ==========
et je ne connue pas où est le problème exactement;
est ce qu'il y a un bibliothèque faux il installer dans visuel c++?
ou il y a un certain compilateur faux il installer sur visuel c++?

et merci.
