C Strings and Pointers - City University of New York

as important to know how to work with another type of string, the C string. The C string has its detractors, some of whom have well-founded criticism of it. But much of the negative image of the maligned C string comes from its abuse by lazy programmers and hackers . Because C strings are found in so much legacy code, you cannot call yourself a ...

C++ Strings

Obtaining a C-style char * from a string Remember, a C++ string is not the same thing as a C-style string (which is merely a char * pointer to a sequence of characters terminated by a null character '\0'). Although old-style C char * strings and C++ strings can co-exist in a program, almost all

•When possible, declare C++ strings for better usability (you will get plenty of C strings in CS 107!) •Any string literal such as "hi there" is a C string. •C strings don't have member functions, and you must manipulate them through regular functions. You also must manage the memory properly -- this is SUPER IMPORTANT and involves making ...

Functions - ROBOTC

• They save time and space by allowing common behaviors to be written as functions, and then run together as a single statement (rather than re-typing all the individual commands). • Separating behaviors into different functions allows your code to follow your planning more easily (one function per behavior or even sub-behavior).
