error code "linker command failed" on custom function

Question

My code will compile, but I'm getting "linker code failed" on my custom function. So I'm not implementing this custom function as I intend to. I still have to deal with case sensitivity and non letters, but I'd like to work out what I did wrong first.

#include <ctype.h>
#include <cs50.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>


// points assigned to each letter of the alphabet
int POINTS[]= {1,3,3,2,1,4,2,4,1,8,5,1,3,1,1,3,10,1,1,1,1,4,4,8,4,10};

int compute_score();

int main(void)
{
    //get input from both players
    string word1 = get_string("player 1: ");
    string word2= get_string("player 2: ");

    //score both words
    int score1 = compute_score(word1);
    int score2 = compute_score(word2);

    //print the winner
    if ( score1 >  score2)
    {
        printf("player 1 wins!!!");
    }
    else if ( score2 >  score1)
    {
        printf("player 2 wins!!!");
    }
    else if (score1 == score2)
    {
        printf("TIE!");
    
int compute_score();
    for (score1=0; score1< strlen(word1); score1++)
    {
        
       score1+= * (POINTS);
    }
    return score1;
    
    for (score2=0; score2 <strlen(word2); score2++)
    {
        score2+= *(POINTS);
    }
    return score2;
}
}     

Answer 1

You have declared your function incorrectly. It should not be within your main function. So, it should look like this:

int main(void)
{
    // code you want in the main function
}

int compute_score()
{
    // code you want in your compute_score function
}

You don't need the ; after the method declaration except for in the prototype declaration at the beginning. The actual function should look similar to the main function.

Hope that helps. If it does, feel free to click the check mark next to my answer. If not, let me know and I can try to help further.
