将整数转为字符串

#include <iostream.h>
#include <string.h>

void fun(char *str, int n)
{
   int i = 0;
  while (1)
 {
    str[8-i] = n%10 + '0';
     n /= 10;
     i++;
     if (n <= 0) break;
 }
    str[i]='\0';

}

void main()
{
   int n = 123456789;
   char *p = new char[10];
   fun(p, n);
   cout<<p;
}
