I have a program that has function power to compute x^n by the formulas:

x^0 = 1
x^n = x * x^n-1 if n > 0

i have already written most of the codes.Needs to be improvise.Help needed!
Thanks

int main()
{
int x, n, i, power1;
power1 = 1;

i = 1;

cout << "Enter base as an integer: ";
cin >> x;

cout << "Enter exponent as an integer: ";
cin >> n;

while ( i <= n )
{
power1 *= x;
++i;
}

cout << power1 << endl;

return 0;
