Thread: [Linker error] undefined reference to `WinMain@16'

I tried writing following code but it says ''
[Linker error] undefined reference to `WinMain@16'

What should I do??

Code:

#include<iostream>
#include<fstream>
using namespace std;

int main()
{
    
int count;
char word[30];
char story[20]; 
}
void countword();


    
    ifstream fin;
    fin.open("STORY.TXT");
    char word[30];
    int count=0;
    while(!fin.eof())
    {
        fin>>word;
        if(strcmpi(word,"the")==0)
            count++;
    }
    cout<<"Number of the word in file are "<<count;
    fin.close();
    system("pause");

}
