what is undefined reference to `WinMain@16

Question

I started recently with programming and this is what I wrote:

#include <stdio.h>
int main() {
    int a,b,c;

    a=2;
    b=7;
    c=a+b;

    printf ("c vale %d\n;c");

    return 0;
}

Something simple I thought but then this error tends to appear:

C:/MinGW/i686-pc-mingw32/lib/libmingw32.a(lib32_libmingw32_a-crt0_c.o):crt0_c.c:(.text+0x3c): undefined reference to `WinMain@16'

can anyone explain me step by step what should I fix?

This happens when you attempt to compile the program as a windowed app instead of a console app. — Cory Nelson, Nov 14 '15 at 23:22
How are you compiling? Please post the full command line (it seems you are using MinGW, probably incorrectly). — Daniel Rose, Nov 14 '15 at 23:23
See if [this question](http://stackoverflow.com/questions/5259714/undefined-reference-to-winmain16?rq=1) helps you. Note that you gave `printf` one too few arguments, which the compiler is capable of warning about. — chris, Nov 14 '15 at 23:23
`main` and `WinMain` is basically the same in both C and C++. — Adam D. Ruppe, Nov 14 '15 at 23:24
Please do at least a basic search for the error message before posting a new question. This has clearly been asked (and answered) here before. — Ken White, Nov 14 '15 at 23:33
"can anyone explain me step by step what should I fix?" Yes. Next question? — user4581301, Nov 14 '15 at 23:50
@user3386109 pssh, typos. should be `printf("c value %d\n", c);` (clearly) — Insane, Nov 14 '15 at 23:51

Compile as console and change this line

   printf ("c vale %d\n;c");

to

    printf ("c vale %d\n", c);  // vale or value ???

_Compile as console_ isn't that informative. If one has to ask this kind of question, one isn't likely to know how to change that information. – Tas Nov 14 '15 at 23:54

I agree with Tas. Although *"compile as console"* is correct, it's not helpful unless you explain *how* to compile as console. – user3386109 Nov 14 '15 at 23:58
