## Description

To check that your program works as you expect, you use `cut_assert_XXX()` where you want to check expected value is got.

e.g.:

    1
    cut_assert_equal_int(3, 1 + 2);

## Details

### cut_assert ()

    void                cut_assert                          (cut_boolean expression,
                                                             ...);

Passes if `expression` is not 0 or `NULL`.

e.g.:

    1
    2
    3
    char *string;
    string = malloc(16);
    cut_assert(string);

    1
    2
    3
    MyObject *object;
    object = my_object_new();
    cut_assert(object, cut_message("my_object_new() should not be failed"));

`expression` : | the expression to be checked.
`...` : | optional message. See `cut_message()` for details.

### cut_assert_true ()
