Document Summary
Engr 101: introduction to computers and algorigthms: lecture 18 - string arrays and. So far we have considered problems where the data we are manipulating is primarily numbers. Often the data we want to work with is not a number, but text. Strings provide a way of manipulating text opbjects. To use strings you must include them by putting an include line at the top of your c++ program: #include Strings can be added together with + . Can send strings to files and standard output using << Strings can be compared with logicals, which evaluate in alphabetical order. Reads a whole line from an input stream, stores in a string. Principle of data abstraction: we can think about algorithms operating on data without consideration of encoding and operation implementation details. Compound data object: composed of more primitive data objects. Strings are compound data objects because they are composed of sequences of chars.
