Question

Answer 1

#include <iostream>
using namespace std;

int main()
{
int arr[] = {5, 2 , 1 , 7 , 9 , 3, 6};
int size = sizeof(arr)/sizeof(arr[0]);

for(int i = 0; i < size; i++)
{
for(int j = 0; j < size - 1; j++)
{
if(arr[j] > arr[j+1])
{
int temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}

for(int i = 0; i < size; i++)
cout << arr[i] << " ";
return 0;
}
