I’m doing the cs50 scrabble problems from probl set 2 and my ‘point’ function doesn’t add point correctly. the function keep ignoring all the ‘if’ and ‘else if’ statement even when there are char that corrospond with that ‘if’ statement.

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

int score1 = 0;
int score2 = 0;
int point(string ply, int score);
void compare(int pl1, int pl2);

int main(void)
{
    string ply1 = get_string("Player 1: ");
    string ply2 = get_string("Player 2: ");

    point(ply1, score1);
    point(ply2, score2);

    point(ply1, score1);
    printf("%cn", ply1[0]);
}



//calculate point
int point(string ply, int score)
{
    for(int i = 0; i < strlen(ply); i++)
    {
        if(ply[i] == ('a'|'e'|'i'|'l'|'n'|'o'|'r'|'s'|'t'|'u'))
        {
            score += 1;
            printf("yesn");
        }
        else if(ply[i] == ('d'|'g'))
        {
            score += 2;
        }
        else if(ply[i] == ('b'|'c'|'m'|'p'))
        {
            score += 3;
        }
        else if(ply[i] == ('f'|'h'|'v'|'w'|'y'))
        {
            score += 4;
        }
        else if(ply[i] == 'k')
        {
            score +=5;
        }
        else if(ply[i] == ('j'|'x'))
        {
            score += 8;
        }
        else
        (
            score += 10
        );
    }
    return score;
}

//compare score
void compare(int pl1, int pl2)
{
    if(pl1 < pl2)
    {
        printf("Player 2 won!n");
    }
    else if(pl1 > pl2)
    {
        printf("player 1 won!n");
    }
    else
    {
        printf("tien");
    }
}

i run this in the cs50 debugger and when it came to the if function, it doesn’t add anything to the score but instead just skip over.
