c - 文件读取错误值

Question

我不知道为什么会这样。我有一个结构可以完美地打印到一个文件中，但是当我尝试读出该文件时，我得到的东西甚至与实际存在的东西相去甚远。写/读部分:

int save_data(){
    char enter = 0;
    int response;
     while(true){
            printf("1. Add new player\n2. View player data\n3. Return to main");
            printf("\nSelection: ");
            scanf("%d", &response);
                if (response == 1){
                     FILE* PlayerFile = fopen("players.txt","w");
                     int i = 0;

                     for (i = 0; i < 1; i++){
                     struct player_info aPlayer = create_player();
                     fprintf(PlayerFile, "Name: %s\nLevel: %d\nStrength Mod: %d\nDexterity Mod: %d\nConstitution Mod: %d\nIntelligence Mod: %d\nWisdom Mod: %d\nCharisma Mod: %d\n", aPlayer.name, aPlayer.Level, aPlayer.Str, aPlayer.Dex, aPlayer.Con, aPlayer.Int, aPlayer.Wis, aPlayer.Cha);
                     }
                     fclose(PlayerFile);
                     return 0;
                     }

                else if (response == 2){
                    struct player_info aPlayer;{
                        char name[30];
                        int Level, Str, Dex, Con, Int, Wis, Cha;
                        };
                    FILE* PlayerFile = fopen("players.txt","r");
                    for (int i = 0; i < 1; i++){
                        struct player_info create_player;
                        fscanf(PlayerFile, "Name: %s\nLevel: %d\nStrength Mod: %d\nDexterity Mod: %d\nConstitution Mod: %d\nIntelligence Mod: %d\nWisdom Mod: %d\nCharisma Mod: %d\n", aPlayer.name, &aPlayer.Level, &aPlayer.Str, &aPlayer.Dex, &aPlayer.Con, &aPlayer.Int, &aPlayer.Wis, &aPlayer.Cha);
                        printf("\nName: %s\nLevel: %d\nStr mod: %d\nDex mod: %d\nCon mod: %d\nInt mod: %d\nWis mod: %d\nCha mod: %d\n\n", aPlayer.name, &aPlayer.Level, &aPlayer.Str, &aPlayer.Dex, &aPlayer.Con, &aPlayer.Int, &aPlayer.Wis, &aPlayer.Cha);
                    }

                    fclose(PlayerFile);
                }
                else if (response == 3){
                false;
                break;}
}
}

实际在文件中的输入:

Name: Hamfast Drummond
Level: 9
Strength Mod: 8
Dexterity Mod: 7
Constitution Mod: 6
Intelligence Mod: 5
Wisdom Mod: 4
Charisma Mod: 3

打印上面的结果:

Name: Hamfast
Level: 6422172
Str mod: 6422176
Dex mod: 6422180
Con mod: 6422184
Int mod: 6422188
Wis mod: 6422192
Cha mod: 6422196

现在，我意识到这一行在所有变量之前都缺少 &，但是当我添加它时，它打印到文件的内容是相同的错误数字，并且读出是正确的那种情况，但它没有将我输入的内容打印到文件中。

作为附带问题，如果允许二合一，我也希望它打印全名而不仅仅是第一个，但我不确定该怎么做。

Answer 1

printf需要带有 %d 格式说明符的值，而 scanf 需要引用

这个:

printf("\nName: %s\nLevel: %d\nStr mod: %d\nDex mod: %d\nCon mod: %d\nInt mod: %d\nWis mod: %d\nCha mod: %d\n\n", aPlayer.name, &aPlayer.Level, &aPlayer.Str, &aPlayer.Dex, &aPlayer.Con, &aPlayer.Int, &aPlayer.Wis, &aPlayer.Cha);

必须是

printf("\nName: %s\nLevel: %d\nStr mod: %d\nDex mod: %d\nCon mod: %d\nInt mod: %d\nWis mod: %d\nCha mod: %d\n\n", aPlayer.name, aPlayer.Level, aPlayer.Str, aPlayer.Dex, aPlayer.Con, aPlayer.Int, aPlayer.Wis, aPlayer.Cha);

换句话说，您(错误地)打印了这些变量的地址，而不是它们的值。
