S C++ does have string type S #include S string hello = “hello”; Strings S Some useful string functions: S char chArray[] = hello.data( ); //get string’s character array S hello.length(); //get length S char oneChar = hello[1]; //can index strings S string wstr = “world”; hello.append(wstr, 0, wstr.length()); //append wstr onto hello to get “helloworld” S wstr.copy(chArray, wstr.length(), 0); //copy wstr string into char array 40
S char string2[20]; S cin >> string2; Character <strong>Arrays</strong> S cin reads in a string (until whitespace) <strong>and</strong> appends null character to end S Make sure input from user
