这是我为一堂课制作的程序。它应该从文件中读取一个字母，然后在游戏中用户尝试猜测该字母。对于每一次错误的尝试，程序都会告诉您实际的字母是在您猜测的字母之前还是之后。
出于某种原因，当我运行它时，循环跳过了 getLetter 函数中的第一次尝试，并且不允许您输入字母。为什么是这样？
#include <stdio.h>
#include <ctype.h>
#define MaxGuesses 5
void instructions();
int playGuess (char solution);
char getLetter ();
int compareLetters (char guess, char solution);
int main()
{
int numGames;
int i;
char solution;
char guess;
int result;
FILE *inFile;
inFile=fopen("inputLet.txt","r");
instructions();
scanf("%d", &numGames);
for(i=1; i<=numGames; i++)
{
printf ("\nThis is game %d\n", i);
fscanf(inFile, " %c", &solution);
result = playGuess(solution);
if (result == 1)
printf("You've WON!\n");
else
printf("You've LOST :(\n");
}
//close file
fclose(inFile);
return 0;
}
void instructions ()
{
printf ("This game consists of guessing letters.\nThe user will have up to 5 chances of guessing correctly,\nupon every failed attempt,\na hint will be provided regarding alphabetical position.\n\nEnter the number of games you wish to play (max 4): ");
}
char getLetter()
{
char userGuess;
printf("\nPlease enter your guess: ");
scanf("%c", &userGuess);
userGuess = tolower(userGuess);
return userGuess;
}
int compareLetters(char guess, char solution)
{
if (guess == solution)
return 1;
else if (guess < solution)
{
printf("\nThe letter that you are trying to guess comes before %c", guess);
return 0;
}
else if (guess > solution)
{
printf("\nThe letter that you are trying to guess comes after %c", guess);
return 0;
}
}
int playGuess (char solution)
{
int numGuesses = 0;
int winOrLose = 0;
char guess;
while(numGuesses < MaxGuesses && winOrLose == 0)
{
guess = getLetter();
winOrLose = compareLetters(guess, solution);
numGuesses++;
}
return winOrLose;
}
