我得到的错误是游戏数量没有正确显示。例如,我选择玩2场比赛。然后,我试图正确猜出第一个数字。显示了解决方案,然后跳转到下一个游戏。但是,第二场比赛显示为第三场比赛而不是第二场比赛。我又试了一次。这次,我猜错了 1 次,猜对了 1 次。第二次猜测后,游戏显示了解决方案,然后尽管我选择玩 2 场比赛并且只进行了 1 场比赛,但比赛停止了。LetterList 文件中字母的顺序是d乙Gw问吨r是你X所以第一场比赛以“d”开始,然后是“B”,然后等等......该错误显示为好像程序本身摆脱了偶数。我不知道它出了什么问题。

printf("\tYou only need to keep guessing for the next letter\n");
printf("------------------------------------------------------------------------------");
printf("\n");

char GetTheGuess()

scanf(" %c", &myGuess);

return myGuess;

void LetterGuessRules()
{
printf("\n*** Instruction: ");
printf("\nYou will have 5 attempts to guess the right answer");
printf("\nIf you guess it right, the game will end with your victory.");
printf("\nOtherwise, you will have to guess again.");
printf("\nPlease have fun!");

最佳答案

问题是你增加了i两次。首先在for循环,并再次在这里:

    //Number of match
printf("\t\tGame %d\n", i += 1);

这可能是因为你得到了 Game 0没有它。简单的解决方法是从 1 而不是 0 开始循环。

i意味着比“循环迭代器”更多的东西我称之为更具描述性的东西 gameNum .

/* from 1 to numGames */
int gameNum;
for( gameNum = 1; gameNum <= numGames; gameNum++ ) {
...
}

请注意,我检查了 gameNum <= numGames而不是 gameNum < numGames因为我们现在从 1 开始。

另外你需要检查文件是否打开,否则如果 letterList.txt 不存在它会崩溃。

#include <errno.h>   /* for errno */
#include <string.h> /* for strerror() */
#include <stdlib.h> /* for exit() */

inPtr = fopen("letterList.txt", "r");
if( inPtr == NULL ) {
fprintf(stderr, "Could not open letterList.txt: %s\n", strerror(errno));
exit(1);
}

最后,我建议不要使用 #define _CRT_SECURE_NO_WARNINGS在学习 C 的同时。那些安全警告很重要。
