Declaring a winner in a coin toss game - c

Question

So, I'm running into an issue with the end of this program. It is supposed to award ten points for each correctly guessed coin flip, and at the end of the 100 tosses, a percentage of correct answers for each player as well as a total score, and finally it is to declare a winner. I seem to have the percentage correct, but the output for total score is jibberish, and I don't know how to get the program to use the results to declare a winner. Help?
#include "stdafx.h"
#include<stdio.h>
#include<time.h>
#include<stdlib.h>
int flip();
int main(void)
{
int player, side, toss, turn = 1, heads = 0, tails = 0;
int Play, wrong1, right1, wrong2, right2, r = (rand() % 2);
puts("Oh boy. My favorite game. Flip the coin. How super exciting. I apparently am little more than a childs plaything... \nEven though I am a program and thus do not have thumbs, hands, feet, skin or even a body, I will (reluctanly) play your silly little game, and 'flip a coin' 100 times.\nI hope you know, there are a lot better things I could be doing right now...\nReal quick, here's a list of things I could be doing right now.\n--Advance scientific research on globular clusters in the Milky Way Galaxy\n---Find the cure for cancer\n----Calculate the rate of deforestation in the Amazon\n-----Create the next generation of low emmission motor vehicles to lower the amount of CO2 in the atmosphere.\nBut, no.

Answer 1

I strongly suggest properly formatting nested if statements with brackets and indentation.
if ( player=1)
if (turn == 1) // start of 2 player gaming
printf("\nPlayer 1, flip the coin. Player 2, take a guess.\n");// player 1 flip
else
printf("\nPlayer 2, it's your turn to flip the coin, Player 1 guess heads or tails.\n"); // player 2 flip
is much more difficult to read than
if ( player=1) {
if (turn == 1) { // start of 2 player gaming
printf("\nPlayer 1, flip the coin. Player 2, take a guess.\n");// player 1 flip
} else {
printf("\nPlayer 2, it's your turn to flip the coin, Player 1 guess heads or tails.\n"); // player 2 flip
}
}
And yes, as mentioned in the comments
if ( player=1) {
should be
if (player == 1) {
And
if (turn == 1)
Play = 1, turn = 0;
else
Play = 2, turn = 1;
should be
if (turn == 1) {
Play = 1;
turn = 0;
} else {
Play = 2;
turn = 1;
}
And you are also using right1, wrong1, right2, and wrong2 without initializing them.
And finally, in printf(), %' should be %% if you are trying to print a percent sign.
