After printing a random two dimensional array , I need to find the first min and first max in the first row?

For example, we have a random 5 x 5 array
1 5 9 4 2
6 4 3 7 9
9 4 6 2 5
2 7 8 5 9
4 1 9 7 7

In the above array we need to look at the first row and find min and max , And then change their columns. So the min and max in the first row are 1 and 9 and the answer should be
9 5 1 4 2
3 4 6 7 9
6 4 9 2 5
8 7 2 5 9
9 1 4 7 7
The columns swapped are highlighted . I have tried to solve this problem withe the following code .

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

int main()
{
int array[5] = {0,0,0,0,0};
int max = array[0];
int min = array[0];
int indexOfMax = 0;
int indexOfMin = 0;
int n, m;
cout << "n = "; cin >> n;
cout << "m = "; cin >> m;

int **array = new int *[n]; // for the output of a random array
for(int i = 0; i < n; i++)
   array[i] = new int [m];

srand((unsigned int)time(NULL));   

for(int i = 0; i < n; i++){    // loop for the array
   for(int j = 0; j < m; j++){
       array[i][j] = rand() % 20;
       cout << array[i][j] << " ";
        if(array[i] > max)   // finding the max in first row
        {
           max = array[i];
           indexOfMax = i;
        }
        if(array[i] < min)  // finding the min in the first row
        {
        min = indexOfMin;
        indexOfMin = i;
        }
        cout << indexOfMin << " " << indexOfMax << endl; 
        }
    }
    cout << '\n';
}
return 0;
}

So, primarily I get this main.cpp:16:11: error: conflicting declaration ‘int** array’. And then i would like to know how to swap the columns of min and max ?
