最后一个了hxd康康怎么做

?啥玩意,题干呢

供参考：

#include<stdio.h>
int main()
{
    char s[] = "Beijing ligong daxue";//char *s = "Beijing ligong daxue";
    int i, j;
    for (i = j = 0; s[i] != '\0'; i++)
        if (s[i] != ' ')
            s[j++] = s[i];
        else
            s[j] = s[i];
    s[j] = '\0';
    printf("%s", s);
    return 0;
}
