对字符串s进行操作：每两个字母之间加一个*，其余字符保持不变。最后整体输出添加*后的字符串。
【样例输入】I had 123_book.
【样例输出】I h*a*d 123_b*o*o*k.
【样例说明】用char数组保存字符串，建议数组长度不小于200.

#include <stdio.h>
int main()
{
char s[1000];
scanf("%[^\n]", s);
char s1[1000];
s1[0] = s[0];
int i, j = 1;
for (i = 1; s[i]; i++)
{
if ((('a' <= s[i] && s[i] <= 'z') || ('A' <= s[i] && s[i] <= 'Z')) && (('a' <= s[i - 1] && s[i - 1] <= 'z') || ('A' <= s[i - 1] && s[i - 1] <= 'Z')))
s1[j++] = '*';
s1[j++] = s[i];
}
s1[j] = '\0';
printf("%s", s1);
return 0;
}
