Most efficient way to find the greatest of three ints

Question

Below is my pseudo code.

function highest(i, j, k)
{
  if(i > j && i > k)
  {
    return i;
  }
  else         


        

Answer 1

The easiest way to find a maximum or minimum of 2 or more numbers in c++ is:-

int a = 3, b = 4, c = 5;
int maximum = max({a, b, c});

int a = 3, b = 4, c = 5;
int minimum = min({a, b, c});

You can give as many variables as you want.

Interestingly enough it is also incredibly efficient, at least as efficient as Ignacio Vazquez-Abrams'solution (https://godbolt.org/z/j1KM97):

        mov     eax, dword ptr [rsp + 8]
        mov     ecx, dword ptr [rsp + 4]
        cmp     eax, ecx
        cmovl   eax, ecx
        mov     ecx, dword ptr [rsp]
        cmp     eax, ecx
        cmovl   eax, ecx

Similar with GCC, while MSVC makes a mess with a loop.
