problem with c code

[john_locke]

hi i have an problem with my c code

#include<iostream>
using namespace std;
int main()
{
int k=35;
printf("%d %d %d %d ",k==35,k=50,k,k>40);
return 0;
}

why the output of these problem is

0 50 35 0

The order in which arguments of a function call are evaluated is undetermined (the comma as separator in a function call is not the same as the comma as sequencing operator), so in your case the evaluation order might be backwards (which would be consistent with the output, but don't rely on it).
PS. Your code is C++, not C.

[mf]

C standard doesn't specify order in which function's arguments are evaluated, so it can depend on your compiler, compile flags, phase of moon, etc...
More on order of evaluation in C here

In your case, it seems that the compiler evaluated arguments from right to left.

#include<iostream>
using namespace std;

This can't be C. It's C++.
