c - 字符串到整数数组

我已经进行了一段时间的研究，但是我不断收到{0,0,0,0,0}或{2751685、2751685等}或{57,58,59,60等）

  void getGuess(int guess[], int length) {
        char thisGuess[length];
        int i=0;
        printf("Enter your guess.\n");
        scanf("%s", &thisGuess);

        for(i=0; i<length; i++) {
            printf("the guess = %d\n",(int)thisGuess[i]) ;
            guess[i] = (int)(thisGuess)-48;

            printf("%d  ", guess[i]);
        }
  }

我想输入一个字符串12345并输入

 guess[0] = 1
 guess[1] = 2
 guess[2] = 3
 etc

关于我的代码的建议？

最佳答案

一个char数组的长度通常不等于它包含的C样式字符串的长度。

void getGuess(int guess[], int length) {
    char thisGuess[length];
    size_t i = 0;
    printf("Enter your guess.\n");
    scanf("%s", thisGuess); // a char *, rather than a char (*)[length] is expected
    size_t guessLength = strlen(thisGuess);
    for(i = 0; i < guessLength; i++) {
        printf("the guess = %d\n", thisGuess[i]);
        guess[i] = thisGuess - '0';
        printf("%d  ", guess[i]);
    }
}

或者，添加

if(!isdigit(thisGuess[i]))
    continue;
