unit testing - Converting datatypes for failing test function in Perl? -


minimum code

use strict; use warnings; use v5.16;    use test::more tests => 2;  is_deeply( [ [0, 0], [1, 0] ], [ [0, 0], [1, 0] ], 'intersects x-axis @ (0, 0) , (1, 0)' );     is_deeply( ( [0, 0], [1, 0] ),  ( [0, 0], [1, 0] ), 'intersects x-axis @ (0, 0) , (1, 0)' );

which returns

ok 1 - intersects x-axis @ (0, 0) , (1, 0) is_deeply() takes 2 or 3 args, gave 5. means passed array or hash instead  of reference @ test44.pl line 14 not ok 2 #   failed test @ test44.pl line 14. # looks failed 1 test of 2 run.

the first code succeeds [[-,-],[-,-]] entries second fails ([-,-],[-,-]) entries. function returns ([-,-], [-,-]) want test if on x-axis.

there many args test, reason why test fails. conversion may needed. however, data chunks big no duplication of data not idea because of speed.

how can proceed testing such data ([-,-],[-,-]) fit expected result efficiently?

use anonymous arrays, each 1 of them interpreted 1 argument:

is_deeply(           [ [0, 0], [1, 0] ],           [ [0, 0], [1, 0] ],           'intersects x-axis @ (0, 0) , (1, 0)' );

the parentheses in original code nothing, lists flattened, i.e. code equivalent to

is_deeply( [0, 0], [1, 0], [0, 0], [1, 0],            'intersects x-axis @ (0, 0) , (1, 0)' );

5 arguments is_deeply.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
