#include <stdio.h>
void main ()
{
int stu[20] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16, 17, 18, 19};
int cout = 0;
int cout1 = 3;
int *p = &stu[2];
int pu;
while ( cout <= 20 )
{
if ( cout1 == 3 )
{
cout1 = 0;
pu = p-stu;
printf (" %d ", stu[pu]);
stu[pu] = -1;
}
p = &stu[( ( ( p - stu ) + 1 ) % 20 )];
if (*p != -1)
{
cout = 0;
cout1++;
}
else cout++;
}
}
帮我结合源文件把printf (" %d ", stu[pu]);写成C++语句，在线等。
能编译成功答案一样就行了。
to:kl_heker 不行啊，答案都不一样的
#include <iostream> //修改头文件
using namespace std;
void main ()
{
int stu[20] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16, 17, 18, 19};
int cout0 = 0;
int cout1 = 3;
int *p = &stu[2];
int pu;
while ( cout0 <= 20 )
{
if ( cout1 == 3 )
{
cout1 = 0;
pu = p-stu;
cout<<' '<<stu[pu]<<' '; //修改输出
stu[pu] = -1;
}
p = &stu[( ( ( p - stu ) + 1 ) % 20 )];
if (*p != -1)
{
cout0 = 0;
cout1++;
}
else cout0++;
}
}
cout改成cout0，cout在C++中是用于输出的，跟变量以示区别
using namespace std;
void main ()
{
int stu[20] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16, 17, 18, 19};
int cout0 = 0;
int cout1 = 3;
int *p = &stu[2];
int pu;
while ( cout0 <= 20 )
{
if ( cout1 == 3 )
{
cout1 = 0;
pu = p-stu;
cout<<' '<<stu[pu]<<' '; //修改输出
stu[pu] = -1;
}
p = &stu[( ( ( p - stu ) + 1 ) % 20 )];
if (*p != -1)
{
cout0 = 0;
cout1++;
}
else cout0++;
}
}

#include <iostream>
然后吧stdio去了
替换printf (" %d ", stu[pu]); 为
cout<<stu[pu];
就行了

如果你是vs200X的编译器的话,
#include <iostream>
using namespace std;
#include <iostream>
using namespace std;

在C++中cout是iosream标准库里的既有对象,你定义了一个cout的变量在C里没问题,在C++里就是灾难,把变量名改成cnt或其它不冲突的名字,再试试
