如何在C中删除字符串数组中的空白元素？

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

void removeWhitespace(char** arr, int size) {
    char** result = (char**)malloc(size * sizeof(char*));
    int count = 0;

    for (int i = 0; i < size; i++) {
        char* str = arr[i];
        int len = strlen(str);
        char* newStr = (char*)malloc((len + 1) * sizeof(char));
        int newIndex = 0;

        for (int j = 0; j < len; j++) {
            if (str[j] != ' ') {
                newStr[newIndex++] = str[j];
            }
        }

        newStr[newIndex] = '\0';

        if (newIndex > 0) {
            result[count++] = newStr;
        } else {
            free(newStr);
        }
    }

    result[count] = NULL;

    // 打印删除空白元素后的结果
    for (int i = 0; i < count; i++) {
        printf("%s\n", result[i]);
    }

    // 释放内存
    for (int i = 0; i < count; i++) {
        free(result[i]);
    }
    free(result);
}

int main() {
    char* arr[] = {"Hello", " ", "World", "", " ", "Cloud", " ", "Computing"};
    int size = sizeof(arr) / sizeof(arr[0]);

    removeWhitespace(arr, size);

    return 0;
}

Hello
World
Cloud
