Why the output is 7.8 though "a" and "b" is integer ... I think a=5 b=7 and the function return m =7

Question

#include <iostream>
using namespace std;

int max(int a,int b)
{ int m;
if (a<b)
m= b;
else
m= a;
return m;
}
int main() {
double x=5.6 ,y=7.8;
cout<<max(x,y);

return 0;
}

Answer 1

The output is 7 with no doubt, since you cast it to int implicitly.

Answer 2

I've gotten these results and I think it's up to compiler on how to deal with implicit type casting.

MS Visual C++ ==> 7
C4Droid. ====> 7.8
SoloLearn compiler ==> 7.8
online codeChef =====> 7.8
online webCompile ===> conversation from double to int warning
online ideOne =======> 7.8

The only exception here is MS VC++ that shows what we are expected. C4droid and others use gcc, g++, and clang
