In c++ how do you rotate array to left and right.

the array is name object array.

for example

you have array look like

tom mary john sam

when i want to rotate it to right i input positive number if i input 2 the array becomes

john sam tom marry

when i want to rotate it to left i input negative number if i input -1 the array becomes

mary john same tom

like based on this program

#include

using namespace std;

void rotate(int a[], int n, int k)

{

int i, b[n];

for(i=0; i

{

b[(i+n+k)%n]=a[i];

}

for(i=0; i

{

cout<

}

}

int main()

{

int a[8]={0,1,2,3,4,5,6,7};

rotate(a, 8 ,-1);

return 0;

}
