[modifica] Istruzioni condizionali

Le istruzioni condizionali eseguono diverse parti di codice a seconda del valore dell'espressione data.

• if esegue parti di codice condizionalmente
• switch esegue parti di codice secondo il valore di un argomento intero

[modifica] Istruzioni di iterazione

Le istruzioni di iterazione eseguono una parte di codice più volte.

• for esegue cicli indicando inizializzazione, confronto, e incremento|
• range-for esegue cicli su un intervallo (dal C++11)
• while esegue il ciclo, controllando la condizione prima di ogni iterazione
• <div class="t-tr-text">do-while

  </div> esegue il ciclo, controllando la condizione dopo ogni iterazione

[modifica] Istruzioni di salto

Le istruzioni di salto spostano l'esecuzione del programma in una posizione diversa.

• continue salta la restante parte del corpo del ciclo
• break termina il ciclo
• goto continua l'esecuzione in un altra posizione
• return termina l'esecuzione della funzione

[modifica] Funzioni

Lo stesso codice può essere riutilizzato in diverse posizioni del programma.

• dichiarazione funzioni dichiarare le funzioni
• dichiarazione funzioni lambda dichiarare le funzioni lambda (dal C++11)
• funzioni template dichiarare funzioni template
• specificatore inline indica che il compilatore inserire il corpo di una funzione direttamente nel codice chiamante
• eccezioni specifiche dichiarare che una funzione genera solo specifiche eccezioni (deprecato)
• specificatore noexcept dichiara se una funzione genera o meno eccezioni (dal C++11)

[modifica] Eccezioni

Le eccezioni sono un modo più robusto per segnalare condizioni di errore rispetto ai codici ritornati dalle funzioni o alle variabili globali di errore.

• espressioni throw segnala gli errori e trasferisce il controllo ai gestori
• blocchi try-catch intercettare le eccezioni originate da specifici blocchi di codice
• specificatore noexcept e operatore noexcept definire e verificare se le espressioni generano eccezioni (dal C++11)

[modifica] Spazi dei nomi

Gli spazi dei nomi forniscono un modo per evitare conflitti sui nomi nei progetti di grandi dimensioni.

• dichiarazioni namespace dichiarare gli spazi dei nomi
• alias spazio dei nomi dichiarare nomi alternativi per spazi dei nomi esistenti

[modifica] Tipi

• tipi fondamentali definiscono il carattere di base, i tipi interi e a virgola mobile
• tipi puntatore definiscono i tipi in possesso di un indirizzo di memoria
• tipi composti definire tipi che contengono diversi membri di dati (essenzialmente la stessa classe)
• <div class="t-tr-text"> enumerazione tipi
