Note

You can also use the + operator to add strings or to add strings and numbers together. It enables you to quickly concatenate strings as well as add numerical data to output strings. Table 1.1 shows that when you add a numerical value and a string value, the numerical value is converted to a string and then the two strings are concatenated.
