c++ - Very first build error after installing Visual Studio 2013. fatal error LNK1561: entry point must be defined -


i guess simple actually, since i'm newbie in c++ i'm unable understand did wrong. of answers (like answers this question) suggest this:

project name -> properties -> expand linker tab -> system -> subsystem:

and change subsystem different types. tried it, gave me error:

fatal error lnk1120: 1 unresolved externals

so assume wrong way. when created project chose visual c++ -> general -> empty project.

my main method int main(); , return 0;. did before in eclipse , fine.

please, should configure launch project successfully? thanks.

this how looks:

#include <iostream>  using namespace std;  class source{     int main(){          cout << "out" << endl;          return 0;     } };

i think may change to:

#include <iostream> using namespace std;  //class source{     int main()     {         cout << "out" << endl;         return 0;     } //};

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
