C program is running but the output is not as expected?

So I'm trying to code a Rock, Paper and Scissor game (my homework) the problem is that it runs but the output is not what I'm expecting Here is the code:

    #include <stdio.h>
    #include <stdlib.h>

    int main (){
    int score1=0, score2=0;
    char p1, p2;
    printf ("ROCK, PAPER, SCISSOR GAME\n[R] ROCK, [P] PAPER, [S] SCISSOR\n");
    while (1){
    printf ("\nPlayer 1: ");
    p1=getch(); printf ("*");
    printf ("\nPlayer 2: ");
    p2=getch(); printf ("*");
        if ((p1=='R')||(p1=='r')&&(p2=='S')||(p2=='s'))
        if ((p1=='P')||(p1=='p')&&(p2=='R')||(p2=='r'))
        if ((p1=='S')||(p1=='s')&&(p2=='P')||(p2=='p'))
        score1++;
        printf ("\nWinner: Player 1\nPlayer 1: %d point%s\tPlayer 2: %d point%s\n", score1, (score1!=1) ? "s" : "", score2, (score2!=1) ? "s" : "");
        if ((p1=='S')||(p1=='s')&&(p2=='R')||(p2=='r'))
        if ((p1=='R')||(p1=='r')&&(p2=='P')||(p2=='p'))
        if ((p1=='P')||(p1=='p')&&(p2=='S')||(p2=='s'))
        score2=++;
        printf ("\nWinner: Player 2\nPlayer 1: %d point%s\tPlayer 2: %d point%s\n", score1, (score1!=1) ? "s" : "", score2, (score2!=1) ? "s" : "");
        if ((p1=='S')||(p1=='s')&&(p2=='S')||(p2=='s'))
        if ((p1=='R')||(p1=='r')&&(p2=='R')||(p2=='r'))
        if ((p1=='P')||(p1=='p')&&(p2=='R')||(p2=='r'))
        printf ("\nWinner: Tie\nPlayer 1: %d point%s\tPlayer 2: %d point%s\n", score1, (score1!=1) ? "s" : "", score2, (score2!=1) ? "s" : "");
        if ((score1==5)||(score2==5))
        break;
    }
    return 0;
    }

This program should run or loop and breaks if one of them got the score 5. Please correct this for me in C language and explain just a little so that i'll understand what the heck is happening. BTW, im using CodeBlocks.
