Question

make the data array a global array (declare the array outside of main) and use an unsigned int for the size because you will have a larger maximum value that you can use:

const unsigned int N = 100;

int array[N];

int main() {...

In addition, this means that you do not need to have a function for sorting using bubble sort. You copy that code into main and sort the array.

Also, keep in mind that every computer has a maximum integer. This value is found by including the <climits> header and is called INT_MAX. You can output this value so that you are aware of the largest value.

Finally, using the random number generator requires the including of time.h, srand(), and rand().

Explanation / Answer

#include <iostream>

#include <stdlib.h>

#include <limits.h>

#include <time.h>

using namespace std;

const unsigned int N = 100;

int array[N];

int main() {

int i, j;

for(i=0;i<N;i++)

array[i] = rand()%INT_MAX + 1;

cout<<"initial array generated by random numbers"<<endl;

for(i=0;i<N;i++)

cout<<array[i]<<" ";

cout<<endl;

for (i = 0; i < N-1; i++)

{

for (j = 0; j < N-i-1; j++)

{

if (array[j] > array[j+1])

{

int temp = array[j];

array[j] = array[j+1];

array[j+1] = temp;

}

}

}

cout<<"sorted array is"<<endl;

for(i=0;i<N;i++)

cout<<array[i]<<" ";

cout<<endl;

cout<<"INT_MAX ="<<INT_MAX<<endl;

// your code goes here

return 0;

}
