How does gtest compare the values in two arrays?

I have read this official document, learn how to do Binary Comparison and String Comparison.

The ASSERT_EQ and ASSERT_STREQ could not work in the array comparison case.

For example

li@li:~/poc$ g++ -I${GTEST_DIR}/include insertion_sort.cpp insertion_sort_unittest.cpp /home/li/libgtest.a -lpthread -o inser_unit
li@li:~/poc$ ./inser_unit 
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from InsertionSortTest
[ RUN      ] InsertionSortTest.Two
insertion_sort_unittest.cpp:18: Failure
Value of: two_sorted
  Actual: { 2, 5 }
Expected: two
Which is: { 2, 5 }
[  FAILED  ] InsertionSortTest.Two (1 ms)
[----------] 1 test from InsertionSortTest (1 ms total)

[----------] Global test environment tear-down
[==========] 1 test from 1 test case ran. (1 ms total)
[  PASSED  ] 0 tests.
[  FAILED  ] 1 test, listed below:
[  FAILED  ] InsertionSortTest.Two

            virtual void SetUp() {}

    };

    TEST(InsertionSortTest, Two){
        int two[] = {5, 2};
        int two_sorted[] = {2, 5};
        insertionSort(two, 2);
        EXPECT_EQ(two, two_sorted);
