cout<

[Kerita]

cout<<a<<endl，输出a的值后，不想换行，只想横向跳到下一制表位置，要怎么改，相当于输出后怎么实现“\t”的功能，如果不加endl的话，“姓名”又全都出现在窗口最底部，求大神指教，要怎么改。

struct member
{
int num;
char name[30];
int score;
struct member *next;
};

struct member mem[10];
struct member *head,*p;

mem[0].num=1;
mem[0].score=100;
strcpy(mem[0].name,"小明");
mem[1].num=2;
mem[1].score=150;
strcpy(mem[1].name,"张琳");
mem[2].num=3;
strcpy(mem[2].name,"李建");
mem[2].score=200;
mem[3].num=4;
strcpy(mem[3].name,"陈燕");
mem[3].score=340;

head=&mem[0];
mem[0].next=&mem[1];
mem[1].next=&mem[2];
mem[2].next=&mem[3];
mem[3].next=NULL;
p=head;

do
{
printf("\t%d\t",p->num);
cout<<p->name；
printf("\t");
printf("\t%d\n",p->score);
p=p->next;

}while(p!=NULL);
}

[漂流的代码]

cout<<'\t';

[derekrose]

cout << "...\t...";

不行？

[Kerita]

具体加在什么地方

[lm_whales]

制表位置，根据已经输出的字符个数计算，然后再按照每个制表符占有的字符个数 计算制表符输出后下一个数据的位置。 例如 puts("123\tabcdefg"); 每个制表符 8字符，该行已经输出“123” ，3个字符，那么输出制表符后，下一个位置在（3+8）/8 =8 的位置 再输出 abcdefg 即输出 123_____abcdefg 其中下划线代表输出\t产生的空白。 其他输出也是这么处理的。

需要严格控制的自己计算以下，不要依赖实现。
