在函数内部定义一个for循环输出行不行？

#include <iostream>
using namespace std;

/**
The caller is responsile for freeing the memory.
*/
int* f(int n)
{
int* a = new int[n];
for(int i=0; i<n; ++i)
a[i] = n;

return a;
}

int main()
{
int n=6;
int* b = f(n);

for(int i=0; i<n; ++i)
cout<<b[i]<<" ";
cout<<endl;

delete [] b;

return 0;
}

楼上正解,用C++中特有的容易犯错了指针就可以解决此问题.
