what should i do for undefined reference to `WinMain@16' collect2.exe: error: ld returned 1 exit status

Question

I am new to C language. I'm currently trying to create an algorithm to make a rank of scores, following a textbook. This is a code shown in the textbook.

struct data{
   int rank;
   int score;
};

void rank1 (struct data *x, int n)
{
    int i, j;
    
    for ( i = 0 ; i < n; i++ ) 
        x [i]. rank = 1;
    for (i=0;i<n;i++)
        for (j=0;j<n;j++)
    if(x [i].score < x [j].score)
    x [i].rank++;

}

Then I got an error saying below.

[Running] cd "c:\Users\soohk\OneDrive\desktop\programming\edition 1\" && gcc tempCodeRunnerFile.c -o tempCodeRunnerFile && "c:\Users\soohk\OneDrive\desktop\programming\edition 1\"tempCodeRunnerFile

collect2.exe: error: ld returned 1 exit status

What can I do for this situation?

You're missing the main function. The program can't run without it. — anastaciu, Jul 09 '20 at 20:19
@anastaciu Thank you for answering. How and where should I add these things? — ohisamadaigaku, Jul 10 '20 at 02:00
This is fairly basic C stuff. Your textbook should guide you. If you [edit] your question, please provide a [example]. — the busybee, Jul 10 '20 at 05:38
