Part 1 Firstrly result &= 0 is used for setting 0 to result variable using bitwise AND operation. Bitwise with 0 will ever return 0. You can write it simply this way: result = 0 The better (much optimal) way of doing this is: result ^= result. (Bitwise XOR) Part 2 This loop will iterate … Read more

[Solved] C++ : write a triangle class using point class [closed]

by

It won’t work because the triangle constructor will attempt to default construct its point members before assigning to them, but point doesn’t have a default constructor. This is because you provide only a point constructor that takes 2 arguments, so the defaulted default constructor is deleted. Instead, you should use a member initialization list to … Read more

[Solved] Java and C: different outputs of same code [closed]

by

Although that code would compile neither in C nor C++, your basic problem is here: System.out.println(h.m1() + “……” + h.m2() + “…….” + h.m3()); In C and C++ there are no constraints on how the compiler orders those calls. It could call m3 then m2 then m1, or m2 then m3 then m1, etc, etc… … Read more
