硬币投掷游戏程序求助：分数输出异常与胜负判定实现问题

Hey there! Let's work through your coin toss game issues—sounds like you're almost done, just a couple of kinks to iron out.

Fixing the Garbled Total Score Output #

The most common reasons for garbled score output are uninitialized variables or mismatched format specifiers in your printf calls. Here's what to check:

• Initialize your score variables: If you declared player1_score and player2_score but didn't set them to 0 at the start, they'll hold random garbage values from memory, which look like "garbage" when printed. Always start scores at 0!

  int player1_score = 0;
  int player2_score = 0;
  

• Use the right format specifier: When printing integers like scores, use %d in printf. If you accidentally used %s (for strings) or another specifier, that'll cause weird output. For example:

  // Correct way to print score
  printf("Total Score: %d\n", player1_score);
  

• Double-check the scoring logic: Make sure you're actually adding 10 points every time a guess is correct. A typo like player1_score =+ 10 (instead of +=) would break this—easy mistake to make!

Adding Win/Loss Determination #

To decide the winner, you can compare total scores first (since each correct guess gives equal points), and fall back to accuracy if scores are tied. Here's a straightforward way to implement this:

// After calculating scores and accuracy
if (player1_score > player2_score) {
    printf("Player 1 takes the win!\n");
} else if (player2_score > player1_score) {
    printf("Player 2 is the champion!\n");
} else {
    // Scores are tied—check accuracy
    if (player1_accuracy > player2_accuracy) {
        printf("Player 1 wins by higher accuracy!\n");
    } else if (player2_accuracy > player1_accuracy) {
        printf("Player 2 wins by higher accuracy!\n");
    } else {
        printf("It's a perfect tie—great game!\n");
    }
}

Full Corrected Code Snippet #

Here's a polished version of your code with these fixes included (I filled in some missing parts like random toss generation and player guess logic):

#include "stdafx.h"
#include<stdio.h>
#include<stdlib.h>
#include<time.h>

int main() {
    const int TOTAL_TOSSES = 100;
    int player1_correct = 0, player2_correct = 0;
    int player1_score = 0, player2_score = 0; // Initialized scores
    float player1_accuracy, player2_accuracy;

    // Seed random number generator for realistic tosses
    srand(time(0));

    for (int i = 0; i < TOTAL_TOSSES; i++) {
        // Simulate coin toss (0 = tails, 1 = heads)
        int toss_result = rand() % 2;

        // Replace this with actual user input if needed
        int player1_guess = rand() % 2;
        int player2_guess = rand() % 2;

        // Update correct counts and scores
        if (player1_guess == toss_result) {
            player1_correct++;
            player1_score += 10;
        }
        if (player2_guess == toss_result) {
            player2_correct++;
            player2_score += 10;
        }
    }

    // Calculate accuracy (cast to float to avoid integer division)
    player1_accuracy = ((float)player1_correct / TOTAL_TOSSES) * 100;
    player2_accuracy = ((float)player2_correct / TOTAL_TOSSES) * 100;

    // Print results
    printf("=== Player 1 Results ===\n");
    printf("Correct Guesses: %d\n", player1_correct);
    printf("Accuracy: %.2f%%\n", player1_accuracy);
    printf("Total Score: %d\n\n", player1_score);

    printf("=== Player 2 Results ===\n");
    printf("Correct Guesses: %d\n", player2_correct);
    printf("Accuracy: %.2f%%\n", player2_accuracy);
    printf("Total Score: %d\n\n", player2_score);

    // Determine winner
    if (player1_score > player2_score) {
        printf("Player 1 wins!\n");
    } else if (player2_score > player1_score) {
        printf("Player 2 wins!\n");
    } else {
        if (player1_accuracy > player2_accuracy) {
            printf("Player 1 wins by higher accuracy!\n");
        } else if (player2_accuracy > player1_accuracy) {
            printf("Player 2 wins by higher accuracy!\n");
        } else {
            printf("It's a tie!\n");
        }
    }

    return 0;
}

Just swap out the random guesses with actual user input using scanf if that's part of your program, and this should work smoothly.
