Array flip

Write a function that will flip the n*n array about its non major diagonal.
Example 3 5 7 makes the non major diagonal in the following manner.
1 2 3 --- 9 6 3
4 5 6 --- 8 5 2
7 8 9 --- 7 4 1

#define N 10
main()
{
int arr[N][N] = {0};
int i=0,j=0,k=1,temp=0;
printf("\n");
initializeArray(arr,N);
for(i = 0; i lessThan N ; i++)
{
for(j = 0 ; j lessThan N-i-1; j++)
{
temp = arr[i][j];
arr[i][j] = arr[N-1-j][N-1-i];
arr[N-1-j][N-1-i] = temp;
}
}
printf("\n");
printArray(arr,N);
}
