Question

Can you help me with a problem on populating an array of 5 circles with random numbers.
The random number would be the radius of the circles.
Here is my code:

#include <iostream>
#include <time.h>
using namespace std;

int main()
{
    // Array 2, below section is to populate the array with random radius
    float CircleArrayTwo [5]; // store the numbers
    const int NUM = 5; // Display 5 random numbers

    srand(time(NULL)); // seed the generator

    for(int i = 0; i < NUM; ++i)
    {
        CircleArrayTwo[i] = rand()%10;
    }

    cout << "Below is the radius each of the five circles in the second array. " <<   endl;
    cout << CircleArrayTwo << endl;

    system("PAUSE");
    return 0;
}

Currently is output the following:

Below is the radius each of the five circles in the second array.
002CF878

Where am I going wrong?

Any help is much appreciated

Answer 1

You are printing the address of the first element of the array.
You could loop over the array and print each element:

for(int i = 0; i < NUM; ++i)
{
    std::cout << CircleArrayTwo[i] << ", ";
}
std::cout << "\n";

Or, if you have C++11 support,

for (auto& x : CircleArrayTwo) {
   std::cout << x << ", ";
}    
std::cout << "\n";
