Question

任何人都可以帮我处理我的代码

int main(void){

    int ctr,wordLength;

    char theWord[99];

    ctr = 0;

    printf("Enter a Word: ");
    scanf("%s", & );
    printf("Enter the letter you want to find: ");
    scanf("%s", & );

    while(ctr < wordLength | theWord[ctr]=='a'){

ctr++;
    }

//output
}

期待输出

输入Word：hello

输入您要查找的字母：z

在单词中找不到字母z。

更正后的代码

int main (void)
{
    int ctr = 0;
    int wordLength;
    char theWord[99], ch;

    printf("Enter a Word: ");
    scanf("%s", theWord);

    printf("Enter the letter you want to find: ");
    scanf("%c", &ch);

    while (theWord [ctr] != '\0')
    {
        if (theWord [ctr] == ch)
        {
            print("Character found at position %1", ctr);
            break;
        }
        ctr++;
    }
    if (theWord [ctr] == '\0')
    {
        printf ("Character not found");
    }
}

你也可以这样做，

#include <stdio.h>
int main(void)
{
   int ctr;
   char theWord[99], ch;
   ctr = 0;
   printf("Enter a Word: ");
   scanf("%s", theWord);
   printf("Enter the letter you want to find: ");
   scanf(" %c", &ch );

  for(int i = 0; theWord[i]; i++)
  {
     if(theWord[i] == ch)
        ctr++;
  }
  if(ctr != 0)
     printf("word is found\n");
  else
     printf("word is not found\n");
}

是的，我们也可以使用while循环来实现它，

int i = 0;
while(theWord[i] != '\0' )
{
   if(theWord[i] == ch)
     ctr++;
     i++;
}
if(ctr != 0)
   printf("word is found\n");
else
   printf("word is not found\n");

我修改了你的代码，它与GCC成功合作

#include<stdio.h>
#include <string.h>

int main(void){

    int ctr = 0,c = 0, wordLength;

    char ch, theWord[99];

    printf("Enter a Word: ");
    scanf("%s", theWord);
    printf("Enter the letter you want to find: ");
    scanf("%c", & ch);

    wordLength = strlen(theWord);

    while(theWord[ctr] != '\0')
    {
        if (theWord[ctr] == ch)
        {
            printf("the letter %c is found in the word\n", ch);
            c++;
        }
        ctr++;
    }
        if (c == 0 )
        {
         printf("the letter %c is NOT found in the word\n", ch);
        }
}

char搜索字符串
