C++ help

How can I remove duplicate numbers for the output?

output should be: 1,2,3,5,6,7,8

#include

using namespace std;

void mergeArrays(int arr1[], int arr2[], int n1, int n2)

{

int i = 0, j = 0;

// Traverse both array

while (i

{

if (arr1[i] < arr2[j])

cout << arr1[i++];

else

cout<< arr2[j++];

}

while (i < n1)

cout<

while (j < n2)

cout<

}

// Driver code

int main()

{

int arr1[] = {1, 3, 5, 7};

int n1 = sizeof(arr1) / sizeof(arr1[0]);

int arr2[] = {2, 3, 5, 6, 8};

int n2 = sizeof(arr2) / sizeof(arr2[0]);

cout<< "Sorted array: ";

mergeArrays(arr1, arr2, n1, n2);

return 0;

}
