    Μαθησιακά αποτελέσματα

    Μετά την επιτυχή ολοκλήρωση του μαθήματος, οι φοιτητές θα είναι ικανοί να:
    • να εφαρμόζουν τις βασικές αρχές ανάπτυξης λογισμικού σε μια διαδικαστική γλώσσα προγραμματισμού,
    • να συγγράφουν κώδικα σύμφωνα με το συντακτικό της γλώσσας C, κλασσικού αντιπρόσωπου της διαδικαστικής σχολής προγραμματισμού,
    • να κατανοούν την έννοια του τύπου δεδομένων και των συναφών λειτουργιών (operations), και να συνθέτουν πολύπλοκους νέους τύπους βασιζόμενοι σε πρωταρχικούς, στοχεύοντας στην ορθή αναπαράσταση των δεδομένων του προς επίλυση προβλήματος,
    • να αξιοποιούν σε προγράμματα την έννοια της συνάρτησης, του τύπου της, των παραμέτρων και της εμβέλειας των μεταβλητών και της κλήσης, και να μπορούν να ορίζουν ορθά νέες συναρτήσεις σε μια γλώσσα προγραμματισμού,
    • να σχεδιάζουν και να αναπτύσσουν μικρού μεγέθους προγράμματα, αξιολογώντας και επιλέγοντας κατάλληλες προγραμματιστικές δομές (εντολές ελέγχου ροής, εντολές επανάληψης) και τους αντίστοιχους βασικούς/σύνθετους τύπους δεδομένων,
    • να συνθέτουν λύσεις σε περισσότερο πολύπλοκα προβλήματα, χρησιμοποιώντας τις έννοιες της αφαίρεσης (abstraction) και αποδόμησης (decomposition) βασισμένη σε διαδικασίες.
