Finding the size of an Icon string
Finding the size of an Icon string |
|
The unary ``*'' operator, applied to a string, returns
the number of characters in the string. For example, the expression
* "foo"
yields the integer 3, the number of characters in the string "foo".
Here's another example. This program prints the length of every line of its input:
procedure main()
while line := read ( ) do
write ( * line );
end
