c - 宣布抛硬币游戏的获胜者

Question

所以，我在该程序的结束时遇到了问题。每掷正确一次，奖励10分，在100次抛掷结束后，计算每位玩家正确答案的百分比以及总分，最后宣布获胜者。我似乎有正确的百分比，但总分的输出是胡言乱语，我不知道如何让程序使用结果来宣布获胜者。帮忙？

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.

我强烈建议使用括号和缩进正确格式化嵌套 if 语句。

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

比

更难阅读

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
    }
}

是的，正如评论中提到的

if ( player=1) {

应该是

if (player == 1) {

还有

if (turn == 1)
    Play = 1, turn = 0;
else
    Play = 2, turn = 1;

应该是

if (turn == 1) {
    Play = 1;
    turn = 0;
} else {
    Play = 2;
    turn = 1;
}

并且您还使用了 right1、wrong1、right2 和 wrong2 而不初始化它们。

最后，在 printf() 中，如果您尝试打印百分号，%' 应该是 %%。
