Title: unresolved externals visual studio 2013
Post by: jameswynands on October 01, 2017, 01:12:12 PM

I am writing a simple program for my class. It is supposed to show a snowman. I am getting the error "unresolved externals"" and when i try to run it, it says " The system cannot find the file specified".

#include <stdio.h> /* printf, scanf definitions*/
#include "stdafx.h"
#include <Windows.h>
#include "function.h"
/* Draws a hat*/
void
draw_hat(void)
{
   printf(" ___\n");
   printf("|  |\n ");
   printf("____\n");
}
/* Draws a circle*/
void
draw_circle1(void)
{
   printf("    * \n");
   printf("*       *\n");
   printf("  *   *\n");
}
void
draw_circle2(void)
{
   printf("     *      \n");
   printf("*         *\n");
   printf(" *       *\n");
   printf("     *    \n");
}
void
draw_circle3(void)
{
   printf("       *    \n");
   printf("*            *\n");
   printf("  *         *\n");
   printf("     *  *     /n");
   return(0);
}

You are trying to return 0 in draw_circle3 which has no return type. So that module won't compile.

There is also no main routine, so it cannot be linked into a console application. I assume you made function.h.
