C語言：在字符串中刪除與某字符相同的字符

用字符指針作函數參數編程實現如下功能：在字符串中刪除與某字符相同的字符。 **輸入格式要求："%s" 輸入提示信息： "Input a string:" "Input a character:" **輸出格式要求："Results:%s\n" 程序運行示例1如下： Input a string:hello,world! Input a character:o Results:hell,wrld!

#include <stdio.h>
#include <string.h>
#define N 100
void  Squeeze(char *s, char c);
int main()
{
    char  str[20], ch;
    printf("Input a string:");
    gets(str);
    printf("Input a character:");
    ch = getchar();
    Squeeze(str,ch);
    printf("Results:%s\n", str);
    return 0;
}
void  Squeeze(char *s, char c)
{
    int i,j,len;
    len = strlen(s);
    for (i = len; i>=0; i--)
    {
        if (s[i] == c)
        {
            for (j = i; j < len; j++)
            {
                s[j] = s[j + 1];
            }
        }
    }
}

#include <stdio.h>
#include <string.h>
#define N 100
void  Squeeze(char *s, char c);
int main()
{                      
    char  str[20], ch;
    printf("Input a string:");
    gets(str);
    printf("Input a character:");
    ch = getchar();
    Squeeze(str, ch);
    printf("Results:%s\n", str);
    return 0;
}                      
void  Squeeze(char *s, char c)
{                      
    char str[N];
    char *t = str;
    strcpy(t, s);
    for (; *t != '\0'; t++)
    {                      
        if (*t != c)
        {                      
            *s = *t;
            s++;
        }
    }
    *s = '\0';  /* 在字符串t2的末尾添加字符串結束標志 */
}
