Question

So far i got this. But i am getting this error :
“Undefined references to `WinMain@16′ ”
Please help.

int sumEvensRecursively(int no1, int no2)
{
no1=5;
no2=20;
if (no1 % 2 == 1)
{
return sumEvensRecursively(no1+ 1, no2);
}

return no1+ sumEvensRecursively(no1+ 2, no2);

}

Answer 1

There are several issues wrong:

• the function is recursive on all control paths, you need a stop condition.

• it appears you pass no1 and no2 as parameters, yet you assign them values on the next lines. What’s the point?

• the error you’re getting is because you’re probably compiling on windows, where the main() is declared something like int _tmain(int argc, _TCHAR* argv[]) and not int main(int argc, char* args[]).

tl;dr-
Conclusion:

Change the main method in your program to int wmain or int _tmain to solve the compiler error.

Change the algorithm to get it to actually work.
