Arrays Array is a data structure that can hold multiple values . These values are accessed by index numbers . " Array is like a variable that can hold multiple values ",  actually array is much more complicated than this but this is a good way of thinking. 1. Making a variable array:                To make a variable array, add   []  after the variable and then close the values in a set of  {}  and inside  {}   separate each value by  ,  . Now  car  is now an array that can hold multiple values ie multiple cars. #include < iostream > using namespace std ; int main () {     string car[] = { " Corvette " , " Ferrari " , " Honda " };         return 0 ; } 2. Output:                Now if you output  car  variable, it will show its memory address where all the values are stored. #include ...
