如何删除数组中特定位置的字符?

So, I am trying to add and remove characters from an array. I have an add_to_array function which works fine. It prints out exactly what it should. However, I can't seem to remove a character from the end of my array. My code at the attempt was:

因此，我尝试添加和删除数组中的字符。我有一个add_to_array函数，它运行良好。它打印出了它应该做什么。然而，我似乎无法从数组的末尾移除一个字符。我尝试的代码是:

void delete_array(char *q, char f)
{
  char *blah = q;
  while(*blah != '\0')
  {
    blah--;
  }
  *blah = f;
  blah--;
  *blah = '\0';
 }

My code for my add_to_array was exactly the same except it was blah++ and I thought removing a character would just be the opposite. It compiles but it prints "segmentation fault (core dumped)" as an output. Where am I going wrong? Thank you for any suggestions/help.

我的add_to_array的代码完全相同，只不过它是什么都没有，我认为删除一个字符正好相反。它编译，但它打印“分割错误(核心转储)”作为输出。我哪里出错了?谢谢你的建议/帮助。

like this:

是这样的:

#include <stdio.h>

void delete_array(char *str, char ch){
//To remove the specified character from a string
    char *to, *from;

    for(to = from = str; *from != '\0'; ++from){
        if(*from != ch)
            *to++ = *from;
    }
    *to = '\0';
}
int main(void){
    char str[] = "application";

    delete_array(str, 'p');
    printf("%s\n", str);//alication
    return 0;
}

In the case of deletion of the character of the particular position you need to include the position in the parameter.

在删除特定位置的字符时，您需要在参数中包含位置。

#include <stdio.h>

void delete_array(char *str, size_t pos){
//Delete the character of the position pos.
    char *p;

    for(p = str + pos; *p = p[1] ; ++p)
        ;
}
int main(void){
    char str[] = "application";

    delete_array(str, 3);
    printf("%s\n", str);//appication
    return 0;
}

The below code shows you how you can remove a character in a string.

下面的代码向您展示了如何删除字符串中的字符。

void delete_array(char *q, char f)
{
  char *blah = q;
  char *temp;
  while(*blah != '\0')
  {
    if(*blah == f){
        while(*blah != '\0'){             
            temp = blah;            
            temp++;            
            *blah = *temp;            
            blah++;        
        }
        break;
    }    
    blah++;
  }
}
