C语言：在字符串中删除与某字符相同的字符

⽤字符指针作函数参数编程实现如下功能：在字符串中删除与某字符相同的字符。**输⼊格式要求：\"%s\" 输⼊提⽰信息：\"Input a string:\" \"Input a character:\"

**输出格式要求：\"Results:%s\\n\"程序运⾏⽰例1如下：Input a string:hello,world!Input a character:oResults:hell,wrld!

1 #include 2 #include 3 #define N 100

4 void Squeeze(char *s, char c); 5 int main() 6 {

7 char str[20], ch;

8 printf(\"Input a string:\"); 9 gets(str);

10 printf(\"Input a character:\");11 ch = getchar();12 Squeeze(str,ch);

13 printf(\"Results:%s\\n\", str);14 return 0;15 }

16 void Squeeze(char *s, char c)17 {

18 int i,j,len;

19 len = strlen(s);

20 for (i = len; i>=0; i--)21 {

22 if (s[i] == c)23 {

24 for (j = i; j < len; j++)25 {

26 s[j] = s[j + 1];27 }28 }29 }30 }

做法⼀

1 #include 2 #include 3 #define N 100

4 void Squeeze(char *s, char c); 5 int main()

6 { 7 char str[20], ch;

8 printf(\"Input a string:\"); 9 gets(str);

10 printf(\"Input a character:\");11 ch = getchar();12 Squeeze(str, ch);

13 printf(\"Results:%s\\n\", str);14 return 0;

15 }

16 void Squeeze(char *s, char c)17 { 18 char str[N];19 char *t = str;20 strcpy(t, s);

21 for (; *t != '\\0'; t++)22 { 23 if (*t != c)

24 { 25 *s = *t;26 s++;27 }28 }

29 *s = '\\0'; /* 在字符串t2的末尾添加字符串结束标志 */30 }
