[section Lazy Statements]
|
|
|
|
Lazy statements? Sure. There are lazy versions of the C++ statements we all know
|
|
and love. For example:
|
|
|
|
if_(arg1 > 5)
|
|
[
|
|
std::cout << arg1
|
|
]
|
|
|
|
Say, for example, we wish to print all the elements that are greater than 5
|
|
(separated by a comma) in a vector. Here's how we write it:
|
|
|
|
std::for_each(v.begin(), v.end(),
|
|
if_(arg1 > 5)
|
|
[
|
|
std::cout << arg1 << ", "
|
|
]
|
|
);
|
|
|
|
(See [@../../example/if.cpp if.cpp])
