task sum4(int a, int b, int c, int d) { int ab = co_await sum(a, b); int cd = co_await sum(c, d); int result = co_await sum(ab, cd); co_return result; } Okay, time for the big boss. The major mind struggle together. And as we all know, if we want to add a, b, c, d together, we need to add ab together, add cd together and add their sums together. 67 void __sum_resume(void* ptr); struct __sum_frame { __sum_frame(int task sum4(int a, int b, int c, int d) { int ab = co_await sum(a, b); int cd = co_await sum(c, d); int result = co_await sum(ab, cd); co_return result; } Customization point - How a compiler may work
