operator: C# Copy customer?.Order = GetCurrentOrder(); The right side of the = operator is evaluated only when the left side isn't null. If customer is null, the code doesn't call GetCurrentOrder. In addition to assignment, you can use null-conditional member access operators with co...
Overload the function call operator here is the c++ code example highlighter- C++ #include <iostream> using std::cout; using std::endl; struct Foo { public: int operator()(int a, int b) const{ return a + b; } }; void test() { Foo f1; int a = 1, b = 2; int c = f1(a...
size_t c = sizeof(7); size_t d = sizeof(3.234); size_t e = sizeof a; The result of the sizeof operator is of a type called size_t, which is defined in the header file <stddef.h>. size_t is an unsigned integer type, perhaps identical to unsigned int or unsigned long int...
