编程学习网为您整理以下代码实例,主要实现:C++函数返回指针,希望可以帮到各位朋友。

#include <iostream>
#include <ctime>

using namespace std;

// function to generate and retrun random numbers.
int * getRandom( ) {
   static int  r[10];

   // set the seed
   srand( (unsigned)time( NulL ) );

   for (int i = 0; i < 10; ++i) {
      r[i] = rand();
      cout << r[i] << endl;
   }

   return r;
}

// main function to call above @R_419_5552@d function.
int main () {
   // a pointer to an int.
   int *p;

   p = getRandom();
   for ( int i = 0; i < 10; i++ ) {
      cout << "*(p + " << i << ") : ";
      cout << *(p + i) << endl;
   }

   return 0;
}
