程序：让字符从两边显示出来

#include<stdio.h>

#include<string.h>

int main()

{

  char arr1[] = "welcome to bit!!!!";

  char arr2[] = "##################";

  int left = 0;

  int right = strlen(arr1) - 1;
  while (left<=right)

  {

  arr2[left] = arr1[left];

  arr2[right] = arr1[right];

  left++;

  right--;

  printf("结果是%s\n", arr2);

  }

  return 0;

}

输出结果为：
